Anticoagulation-related intracranial extrace and anticoagulant pharmacotherapy on outcomes rebral hemorrhage hiv infection time period cheap atacand 16 mg otc. Identify shift in the regular areas of the brain buildings including in the cephalad or caudal directions; hiv infection rate unprotected generic 4 mg atacand amex. Scan may be carried out axial/sequentially antiviral que son order atacand australia, but may be carried out helically in greater finish scanners (see under for dialogue of execs and cons of axial vs. This may be completed by both tilting the affected person’s chin toward the chest (“tucked” position) or tilting the gantry. A delay of four minutes between contrast injection and the start of scanning is typical. The choice as to whether to use axial or helical must be influenced by the particular affected person indication, scanner capabilities, and picture high quality requirements. Users of this doc 1 should consider the data in the following desk and seek the advice of with each the producer and a medical physicist to assist in figuring out which mode to use. Patient lying in supine position, arms resting alongside the body, secure head properly in the head holder, help decrease legs. In order to optimize picture high quality versus radiation dose, scans are provided inside a maximum scan field of 300 mm with respect to the iso-center. Therefore, affected person positioning has to be carried out accurately to guarantee a centered location of the skull. Use the lateral laser beam to be sure that the affected person is positioned in the center. In order to optimize picture high quality versus radiation dose, scans are provided inside a maximum scan field of 300 mm with respect to the isocenter. Awakening with or experiencing the abrupt onset of focal neurologic defcits is the hallmark of the diagnosis of ischemic stroke. The most common presenting symptoms of ischemic stroke are speech disturbance and weakness on one-half of the body. The most common conditions that can mimic a stroke are seizure, conversion disorder, migraine headache, and hypoglycemia. Taking a affected person historical past and performing diag nostic research will normally exclude stroke mimics. Neuroimaging is required to differentiate ischemic stroke from intracerebral hemor rhage, in addition to to diagnose entities aside from stroke. The alternative of neuroimaging is determined by availability of the method, the affected person’s eligibility for thrombolysis, and presence of contraindications. Subarachnoid hemorrhage presents mostly with sudden onset of a extreme headache, and noncontrast head computed tomog raphy is the imaging test of alternative. Cerebrospinal fuid inspection for bilirubin is really helpful if subarachnoid hemorrhage is sus pected in a affected person with a traditional computed tomography outcome. Public schooling about common presenting stroke symptoms might improve affected person information and scientific outcomes. Rapid, accurate tors embody hypertension, atrial fbrilla evant fnancial affliations. For the private, noncom-528Downloaded from the American Family Physician web site at Patients and family members must be educated about stroke symptoms and the need for urgent evaluation. A = constant, good-high quality affected person-oriented proof; B = inconsistent or limited-high quality affected person-oriented proof; C = consensus, illness-oriented proof, traditional apply, expert opinion, or case series. Most Common Symptoms and Signs of Posterior Circulation Stroke Symptom or signal Prevalence (%)8 Posterior circulation strokes may be difficult Symptoms to diagnose. One potential area of confusion is when Dizziness 47 sufferers current with dizziness, which is a typical Unilateral limb weakness 41 concern normally but an uncommon presentation for Dysarthria 31 stroke. In a inhabitants-primarily based study of adults older than Headache 28 44 years presenting to the emergency division or Nausea or vomiting 27 immediately admitted to the hospital with a principal con Signs cern of dizziness, solely 0. Dysarthria 28 However, in sufferers presenting with acute vestibular Nystagmus 24 17 syndrome defned by one hour or extra of acute, per Information from reference 8. The test additionally may be carried out by turning the affected person’s head again to center from 10 to 20 degrees off-center. Nystagmus is enhanced when the eye strikes toward the side of the fast beat and decreases or disappears when the eye strikes toward the side of sluggish beat. With central lesions, the fast beat of nystagmus might change directions toward the direction the eyes are transferring, hence the time period “direction-altering nystagmus. Stroke Mimics and Distinguishing Features Condition Distinguishing options Seizure History of lack of consciousness, seizure exercise, postictal state, or historical past of epilepsy normally present26-31 Somatoform or conversion Fluctuations in scientific image, nonanatomic symptoms or signs or historical past of mental illness9,29 disorder Among the commonest stroke mimics in sufferers treated with thrombolysis Reported prevalence of 0. Guidelines for the early management of sufferers with weighted pictures, have higher decision than noncon acute ischemic stroke: a guideline for healthcare professionals from the American Heart Association/American Stroke Association. Acute intracranial vas infarction (arrow) in the best-center cerebral artery dis cular imaging is really helpful if intravascular remedy tribution not evident on the computed tomography.

Systematic evaluate of mass media interventions designed to improve ischemic stroke mimics among 411 code strokes on the University of public recognition of stroke symptoms, emergency response and early California, San Diego, Stroke Center. Early evaluation and treatment of stroke reduces motor and cognitive deficits and lowers mortality. Types of Stroke and Risk Factors There are two forms of stroke, each of which lead to a discount in oxygen reaching the brain. Major causes embody arterial thrombus, venous emboli that migrate, atrial fibrillation, arteritis, patent foramen ovale, left ventricular dysfunction, and refractory septic shock. Intracerebral hemorrhages are sometimes caused by a rupture of the vessels as a result of long-time period atherosclerotic injury and arterial hypertension. Time of onset is outlined because the time the affected person was final identified to be neurologically regular. Physical Exam (Anderson, 2016) In addition to a radical neurological assessment and use of stroke assessment instruments, essential components of the bodily examination embody. Diagnostic Studies (Anderson, 2016) Immediate diagnosis and treatment are required to forestall brain tissue hypoxia and demise (Davis & Lockhart, 2016). Oxygen saturation (O2 sat) Rule out acute ischemic stroke related to hypoxemia. Blood alcohol & Include liver panel for sufferers with suspicion of alcohol toxicology intoxication. Lumbar puncture Used to rule out suspected subarachnoid hemorrhage when brain imaging is adverse. For sufferers that have been treated with alteplase, delay aspirin until 24 hours following remedy. Endovascular thrombectomy: mechanical removing of the thrombus to reestablish blood move. Superficial temporal artery to center cerebral artery bypass graft: the graft bypasses the cerebral vessel that has the thrombus or unruptured aneurysm (may treat ischemic stroke). Nursing Interventions for the Stroke Patient (Davis & Lockhart, 2016; Powers, et Al. Minimize pores and skin friction and pressure; provide help surfaces; keep away from excessive moisture; and maintain diet and hydration to forestall pores and skin breakdown.

Your child will hear and really feel a rhythmic knocking sound antiviral medication for genital warts generic atacand 16mg fast delivery, like a drumbeat antiviral used for shingles discount atacand 4 mg with amex, when the machine is scanning hiv symptoms five months after infection order line atacand. You might not have the ability to hiv infection rates uk generic 16 mg atacand with amex stay in the identical room with your child throughout this test; however, you and the employees can always hear and see your child. Before and after the scan, a particular drugs is given to shield the thyroid gland from the radioactive substance within the tracer. For occasion, there are particular dietary directions to comply with, and there may be additional directions if your child wants sedation. A small spherical probe (transducer) is then placed on the jelly and moved round to get a transparent picture of the tissue or organ. The tests additionally present if the degrees of sodium, potassium, and lots of other elements within the blood are normal. One reason is to see how remedy is affecting the bone marrow, where blood cells are made. Other reasons are to see if your child wants a transfusion or is at increased risk for infection. A differential rely (or “diff”) refers to the distribution of the assorted types of white cells within the blood. The quantities of creatinine within the blood and within the urine are used collectively to measure kidney perform. After the tracer is given, comply with-up tests are accomplished to decide how quickly the tracer passes through the kidneys and is faraway from the body. Certain genes may be partly responsible for how medicines are processed by the body. By performing these blood tests, we hope to learn how to higher use these medicines in kids with cancer. In some childhood cancers, blood and/or body fuids may be tested for specifc tumor markers to assist decide if cancer is current and monitor response to remedy. A small quantity of urine is collected in a cup and sent to the laboratory to be tested. Your child might put on headphones and/or go right into a soundproof booth for this testing. Small electrodes might be taped to your child’s head, and their brainwave responses to various sounds might be recorded. This probe sends sound waves to the guts, and the returning sound waves create a picture of the guts. Small stickers, known as leads, are placed on the chest and typically on the legs and arms. When the rhythm must be measured over a number of hours or a day, the test tools known as a Holter monitor. The test measures how a lot air the lungs can hold and the way nicely your child can push air out of the lungs. Your child might be requested to blow right into a plastic mouthpiece related to a machine. The machine measures the quantity of air breathed in and the drive of the air breathed in and out. Your child will in all probability be requested to repeat the test a few times to get an accurate studying. For extra details about tests and procedures at your hospital, check with the “Information from My Hospital” section of this handbook, or ask your health care team. The tremendous progress that has taken place in creating profitable therapies for children with cancer has been made attainable through clinical trials. For every new clinical trial, a group of doctors, nurses, and other consultants plan how the remedy might be given. New clinical trials are planned based mostly on the outcomes of previous trials, taking the best recognized remedy and asking what might make it higher. The information gained from clinical trials has improved remedy for children with cancer by growing survival charges and reducing unwanted effects and long-term effects of remedy. Each part of a clinical trial builds on the previous phases, with the general goal of creating higher therapies. The doses are increased in teams of patients until unwanted unwanted effects are observed. Facts About Clinical Trials the fndings from clinical trials add to information and progress within the remedy of cancer. Since childhood cancer is rare, by attempting completely different therapies and looking out on the results we are able to fnd out which therapies are the best rather more quickly. If you resolve not to enroll in a clinical trial, your child will receive what is named the present standard remedy. Randomization Your child may be in a clinical trial that compares two or extra remedy plans. The other plan or plans have slight changes or additions which will improve survival charges, control disease longer, cause fewer or less critical unwanted effects, and/or decrease days spent within the hospital. To be taught if one remedy is better, every child is assigned randomly to one of many remedy plans by a computer. Randomization is a process like fipping a coin that assures every child has a fair and equal likelihood of being assigned to any of the remedy plans. In most clinical trials, we do not know which remedy plan is better until the entire kids on the trial have accomplished remedy and have been adopted for a number of years. However, if one of many remedy plans is found to be higher or safer than the others while the trial is in progress, enrollment on the trial is suspended and all kids currently within the trial are given the remedy with the best results, if attainable. You might be requested to sign a type that describes the clinical trial together with the remedy plan. This type lists the risks and benefts of the remedy plan and provides you with a list of the unwanted effects of the medicines and any additional remedy. If your child is sufficiently old to understand, they are going to be requested if they give their permission to take part within the clinical trial. When a minor child (normally a baby youthful than 18 years previous) gives permission, the child is giving assent. If your child is legally thought of an grownup, they will need to give consent and sign the form themselves. Every day within the hospital or at every clinic visit, your health care team will talk with you about the plan of care. This is your likelihood to ask questions and resolve whether or not you agree with the plan. If you resolve to have your child take part in a clinical trial and later change your mind, you might remove your child from the clinical trial at any time. Your health care team will proceed to provide the best care attainable in your child. Treatment Plan A member of your health care team will evaluate the remedy plan within the clinical trial in your child. A schedule for every remedy, test, and process is listed on a remedy supply map (typically known as a highway map), which is an summary of your child’s plan of care. You can take a look at the remedy supply map to see when the subsequent remedy is scheduled. You and/or a member of your health care team might create a calendar that contains the information out of your child’s remedy supply map. For extra info, please see ‘Effects of Cancer Treatment on the Bone Marrow,’ starting on web page 60. Bring your Hope and Help Journal or a pen and paper to your assembly to take notes. Each kind of childhood cancer may be treated in a different way, relying on what researchers have found to be the simplest remedy for the actual kind of cancer. Your child might receive one or a combination of the following therapies at completely different time points in their remedy. Several types of chemotherapy medicines may be used because they every cease cell progress or destroy cells differently. Often the unwanted effects get higher or go away as soon as the chemotherapy remedy is over. Chemotherapy may be given by: · Mouth · Into a vein · Into the muscle · Into the spinal fuid Your child’s chemotherapy may be given by one or more of these methods.

The early oedema spontaneous extravasation of blood into the mind is normally secondary to plasma proteins current in the Iparenchyma. Hypertension continues to be basal ganglia, thalamus, brainstem (predominantly the the primary trigger, being responsible for roughly fifty five% pons), and cerebellum.

Weeks to months Friable brown clot Organisation of the haematoma with phagocytosis of blood and necrotic tissue by macrophages. Cocaine and amphetamines are sympath omimetic brokers recognized to have effects on pulse and blood pressure. Size and placement of the haemor rhage, together with age and presence of hyper tension, characterize the primary prognostic indica tors.

Intraventricular extension of supratentorial intracerebral hemorrhage: the modified Graeb scale improves outcome prediction in Lund Stroke Register. The hazard price is the hazard over an outlined time interval, and could be derived as a function of survival. In epidemiology, the time period is usually used to describe death in a population and presented as a price (deaths per individual-years at risk). Retrospective examine: A examine the place the event or publicity has occurred prior to the examine begin. However, several types of intracranial hemorrhage could be current concurrently as illustrated in Figure 1. A current Italian population-primarily based examine showed a decline in incidence in all age groups between 1994-1998 and 2011-201240. Age-standardized incidence of hemorrhagic stroke per one hundred 000 individual-years for 2010, from Krishnamurthi et al. Stroke incidence in Sweden 1998 to 2014, age-standarlized to the Swedish population in 2015. The non-terminal arterioles (30-one hundred μm in diameter) have 2-three smooth muscle cell layers, whereas larger cerebral arteries (>one hundred μm in diameter) have between 4-20 layers54. Other types of pathology in small cerebral vessels which have been attributed to hypertension includes: lipohyalinosis 17 (characterized by damaging lesions in forty-300 μm vessels) together with the acute type fibrinoid necrosis; and hyaline arteriolosclerosis (hyaline wall thickening and lack of smooth muscle cells in forty-one hundred fifty μm vessels) which in flip would possibly have an effect on autoregulation and expose distal vessels to tare 57, fifty eight. Fisher introduced a mannequin for hematoma growth which means that the clot puts pressure on vessel in its periphery which causes further vessel ruptures and more bleeding59. This might be defined by a considerably abrupt increased pulse pressure and thereby increased vessel stress, in the relatively small arterioles branching directly from the proximal parts of the larger main cerebral arteries in comparison with arterioles originating from branches that are more distal56. Tissue factor launched from the damaged endothelium and phospholipid complexes, uncovered by activated thrombocytes, set off a series of enzymatic conversion that ends with the activation of thrombin that converts fibrinogen into fibrin forming a clot64. Hart hypothesized that the anticoagulative results of warfarin would possibly exacerbate hemorrhages that may otherwise have been sub-clinical68. Diabetes Mellitus Patients with diabetes mellitus have an increased risk for cerebral small vessel disease75, presumably because of hyaline arteriolosclerosis or impaired vascular reactivity which is associated with diabetes57. A lowered platelet count and decreased production of professional-coagulative components produced in the liver amongst sufferers with excessive alcohol consumption would possibly contribute to the increased risk83. Ethnic origin defined 42% of the variance in incidence in one massive meta analysis37. Differences in environmental and way of life risk-factor distribution70, 71 is a probable trigger for geographical variations as immigrant populations have been proven to differ from their area of origin37. Larger clots volumes enhance intracranial pressure because of the limited intracranial quantity and may thereby trigger each distant mechanical injury. It is therefore nonetheless debated if perihematomal hypoperfusion inflicts ischemia in the clot perifery94, ninety five. Subacute Phase (4 h to 7 days) Several different biochemical components are launched from the clot into the encircling tissue. One of those is thrombin, which impacts endothelial cells and enhance blood mind barrier disruption95. Thrombin also asserts a toxic impact in neurons and astrocytes, and triggers microglia activation94, ninety five. The breakdown of erythrocytes triggers a release of ferrous iron (from hemoglobin) and different breakdown merchandise, which induces further mind injury94, ninety five. The hematoma triggers an inflammatory response, first with activation of microglia (within the first hours) which in flip triggers a cascade of reactions ending in neural and glial apoptosis, and breakdown of connective tissues94, ninety five. Secondly, an influx of neutrophils trigger formation of vasogenic edema (by disruption of the blood mind barrier), releases reactive oxygen species and proinflammatory proteases, and facilitates monocyte entry over the blood-mind barier95. Chronic Phase (days-months) Microglia and macrophages gradually phagocyte the components of the blood clot and thereby cut back the hemorrhage until only a fluid stuffed cyst or collapsed mind defect stays. An enhance in hematoma quantity leads to more tissue injury and will increase the risk for neurological deterioration and hematoma enlargement is one of the most necessary predictors for poor practical outcome and quick-time period case fatality102. Much effort has gone into attempting to set up what components drive enlargement and how it may be prevented. Hemostatic Therapies to Reduce Hematoma Expansion Hemostatic therapy has been the second primary technique for stopping hematoma enlargement and could be divided in therapies specializing in enhancement of hemostasis or reversion of anticoagulation/antithrombotic therapies. Other Complications the neural injury caused by stroke normally can have a broad range of penalties together with. These lesions predict a three-fold risk enhance for stroke, and a two-fold risk enhance for dementia and death, respectively138. Additionally, lesions in the left and right basal ganglia are rated from zero to three (no lesion to confluent lesions)146. In another meta-evaluation primarily based on 9 population-primarily based studies, the 1-yr case fatality was almost similar (54%)149. The quick-time period (21/30-day) case fatality is lower in excessive-earnings countries (25%-35%) in comparison with low-earnings countries (30% 48%)34, and the lowest rates are found in Japan (thirteen. The 30-day and 1-yr case fatality has remained stable37 but in a examine from the Netherlands a decline was reported amongst youthful sufferers (<75 years) whereas the case fatality remained unchanged amongst older sufferers (≥75)38. These three-month case fatality rates 28 are much like the 20%-36% 28/30-day case fatality rates that have been reported in Swedish cohorts from 1993 to 200022, 26, forty five. Nonetheless, trends in this type of register knowledge should be interpreted with nice warning as the accuracy of diagnoses would possibly vary163. In another abstract, the proportions of sufferers living independently ranged from 12% (Estonia) to 39% (Italy) but observe-up instances and outcomes assessments differed considerably between the 6 included studies37.

Case Report: A 20-yr-previous lady, with recurrent oral aphthosis, offered with acutely proper blurred vision and was recognized with an optic neuritis. One yr later she complained of lack of power in the left limbs and had a light left hemiparesis. Optic neuritis as presenting manifestation of Behçet’s Portugal Disease with multisystem involvement. International Journal of Clinical Neuro 2Rheumatology Department, Centro Hospitalar de São João, Porto, Portugal sciences and Mental Health 2016; three(Suppl. This is an open access article distributed underneath the Creative Commons Attribution License, which allows unrestricted use, distribution, and reproduction in any medium, supplied the original work is properly cited. Neu recurrent oral aphthosis (>three episodes/month) and purpura rological involvement, which may affect up to forty nine% of pa after “flu-like” syndrome at age 7, offered with acutely tients, is a crucial reason for lengthy-time period morbidity and proper blurred vision and impaired color vision. The visu takes primarily considered one of two varieties: parenchymal (most often al disturbance developed over a period of hours and was meningoencephalitis) and non-parenchymal (most often associated with pain with eye movements; visual acuity vascular thrombosis inside large veins). The remainder of the neurologic and systemic es, the neurological presentation can precede systemic examination was normal. A pathergy check was So, optic neuritis is an exceedingly uncommon presentation of performed and was optimistic. Discussion We present a case the place the clinical and laboratory fea tures have been very typical of inflammatory harm to the op tic nerve. A very good response to sys ical response was noted inside 72 h, but restoration was temic corticosteroids was noted, similarly to our patient. Be follow-up, visual acuity was 10/10 in both eyes, with full yond cerebral venous thrombosis and meningocephalitis, visual fields and normal ophthalmoscopic appearances. In the acute One yr later, the patient was admitted with dizzi section, most sufferers have single lesions; nonetheless, in the ness and imbalance; neurological examination revealed a persistent section, extra diffuse involvement may be seen, with delicate left hemiparesis. Thus, in an atypical clinical context, the differ (some with decreased measurement) and two new frontal white ential analysis with multiple sclerosis may be extremely matter lesions, subcortical at proper and sub-insular at left. Colonoscopy the same time or later is determined by the severity of disease confirmed a change in the vascular pattern in the rectum with and the response to steroids. In this case, and given the erythema and friability; histology was suggestive of ulcer good preliminary response to a cycle of corticosteroids, it was ative colitis. The patient began mesalazine and required 2 determined to delay the onset of immunosuppressive thera cycles of prednisolone (zero. On the suspicion of drug toxicity, azathioprine and the case that responds poorly to steroids, or if relapse is mesalazine have been stopped. Due to the ble many months after the visual disturbance, when different severity of the disease, the ineffectiveness of azathioprine systemic features appeared. Some sufferers can take a number of years International Journal of Clinical Neurosciences and Mental Health 2016; three(Suppl. Exciting developments have Lancet Neurol2014; thirteen: eighty three–99 occurred over the previous decade in understanding of optic neuritis pathophysiology, and these developments have been Queen Square Multiple translated into therapy trials. Atypical types of optic neuritis can happen, either in Department of Brain Repair association with different inflammatory issues or in isolation. Differential analysis consists of varied optic nerve and and Rehabilitation(A T Toosy), retinal issues. Optical and Department of coherence tomography can show retinal axonal loss, which correlates with measures of persistent visual dysfunction. It occurs all through the world and has a lot of cases and occurs during the disease in about 70%, Correspondence to: causes. This variability is Severity varies widely and tends to attain its nadir inside in all probability due to the broader differential analysis and the 2 weeks. Dyschromatopsia occurs early and has a variable background inhabitants risk of those circumstances. In this Review we offer an acute section, and purple–green extra frequent at replace of those developments. Other studies principally show both purple–green with purple–green than with blue–yellow defects, but in and blue–yellow colour defects with neither sort sufferers with visual fields dominated by perifoveal dominating. Panel 1:Terminology for optic neuritis Optic neuritis lesions posterior to the orbit are much less more likely to trigger pain. Research studies generally use totally different classification the Pulfrich effect (panel three). Central defects have been extra frequent than An different technique classifies optic neuritis by trigger. A relative afferent pupillary defect is isolated optic neuritis, persistent relapsing inflammatory optic usually seen, although involvement of the other optic neuropathy, solitary isolated optic neuritis). Diffuse optic disc swelling is present demyelinating optic neuritis has been also been used as a in a third of cases but the optic disc is normal in two pathology-based definition, although this time period can be not best 22 thirds (retrobulbar optic neuritis). Six sufferers (2%) had a visual acuity of 20/40 two of 4 locations: juxtacortical, periventricular, or worse and only three (1%) had a visual acuity of 20/200 or worse in both eyes. These sufferers are recognized Patient historical past and neuro-ophthalmic examination can retrospectively, after prolonged follow-up, with solitary be used to search for different causes of acute monocular optic neuritis or recurrent optic neuritis. The successive triplet, the contrast decreases in logarithmic steps symptom of phosphenes must be clinically distinguished by zero·15 log units. The patient is asked to learn alongside and from a scintillating scotomas, that are usually associated down the chart until the detection limit is reached, scored with visual aura of migraine. High scores indicate higher blind area surrounded by a margin of sparkling lights that contrast sensitivity, measured at the peak of the contrast can change form or move over a time period, sometimes sensitivity function (about one to two cycles per degree). The patient is small increases in physique temperature, sometimes attributed to asked to distinguish totally different colored numbers, but this train, sizzling baths or showers, or sizzling weather circumstances. The patient has to acknowledge luminant stimuli briefly 20/20 or 6/6 vision is normal; 20/200 or its equivalent 6/60 offered in several locations. Goldmann perimetry is dynamic and depends resolution at four m and offers a linearly steady variable on the patient detecting a luminant stimulus transferring in amenable to parametric statistics. The check is done by a skilled transformed to Snellen equivalent scores, and vice versa. Its advantages over Humphrey contrast acuity charts at detection of visual dysfunction in perimetry are that patient compliance may be assessed and optic neuritis. Final diagnoses for the recurrent retrospective case analysis reported findings from group have been vasculitis or connective tissue disease in 74 sufferers with recurrent or bilateral optic neuritis. Visual evoked potentials Appearance Normal or swollen optic disc Severe optic disc swelling, macular star (neuroretinitis), can be used to diagnose optic nerve involvement but do optic disc haemorrhages, anterior—posterior phase not robustly distinguish between totally different acute optic inflammation, marked retinal exudates neuropathies, although a delayed but nicely preserved P100 Other Uhthoff’s phenomenon, Family historical past, neoplastic historical past fifty four–fifty six Pulfrich effect, earlier self waveform is characteristic of demyelination. Visual limiting neurological episodes evoked potentials with pattern electroretinograms can distinguish between optic nerve and macular pathology. Table 2: Features of typical and atypical optic neuritis Optical coherence tomography is used to exclude macular pathology in acceptable cases.
