Disc Edema

Introduction: Optic disc edema can be a manifestation of various neurological disorders. Identification of those causes is possible in most cases using tests like visual acuity, color vision, visual field and suitable radiological imaging. Study in Nepalese population with regard to optic disc edema is scarce. Hence this study aims to act as a guideline for evaluation of such cases and help in further studies in this regard. Methods: A descriptive, cross-sectional study was conducted in all cases of optic disc edema presenting to neuro-ophthalmology clinic of B.P. Koirala Lions Centre for Ophthalmic Studies from January 2011 to June 2012. A detailed history was obtained and proper ocular and nervous examination was done by ophthalmologist and neuro-physician. Assessment of visual acuity, color vision, contrast sensitivity and visual field along with radiological tests were done in all possible cases. Results: Out of all the cases evaluated, 38 cases where causes of optic disc edema could be established were included in the study. The commonly affected age group was 31 to 40 years (26.3%) and most of them were males. The commonest cause observed was optic neuritis (36.8%). Others were papilledema, idiopathic intracranial hypertension, toxic optic neuropathy, non-arteritic anterior ischemic optic neuropathy (NA-AION), compressive and traumatic optic neuropathy. Conclusion: Optic neuritis and papilledema should be considered as common differential diagnosis in patients with optic disc edema. NA-AION is a relatively uncommon disease among Nepalese population.

Unique Case

Purpose : We present a unique case of atypical anterior optic neuritis resemble anterior ischemic optic neuropathy Methods : This was a single case study, with a patient was followed up for 2 months. Visual acuity, visual field, color vision, intraocular pressure, and ocular anatomy, were examined. Results : A female patient 54 y/o with chief complain sudden blurred vision on both eyes after woke up in the morning without redness and tearing 4 days before day of visit. History of systemic and ocular diseases were denied. Visual acuity was 0.5/60 (superior) right eye and 1/60 (superior) left eye, couldn’t be corrected. Relative afferent pupillary defect was observed in right eye. Biomicroscopic examination of anterior segment and intraocular pressures were normal. Funduscopy revealed ill defined margin at optic nerve head for both eyes suggested papilledema. At the present we couldn’t examined color vision. Visual field examination showed inferior altitudinal defect (more severe in right eye). Consultation to internal medicine and laboratory examination such as: complete blood count, lipid profile, blood glucose, and electrocardiogram were done to confirm our diagnosis. Clinically, the diagnosis of the disease more likely to be the anterior optic neuritis. Follow-up after 2 months has normal visual acuity, visual field, and color perception after steroid treatment. Conclusion : Anterior optic neuritis might have a very similar clinical presentation of anterior ischemic optic neuropathy upon early manifestation.

Purpose: To evaluate the etiology and clinical presentation of cases with optic disc edema presenting to a tertiary eye center of Nepal. Background: The etiology of optic disc edema ranges from relatively benign to potentially sight and life threatening conditions. Till date very few studies have been done on disc edema in Nepal. Method: The authors conducted a prospective, descriptive study at B.P. Koirala Lions Center for Ophthalmic Studies (BPKLCOS), Nepal. All cases with disc edema presenting to the out patient department (OPD) from January 1, 2014 to June 30, 2015 were included in the study. Results: Total 112 patients were included in the study, out of which diagnosis could be established in 99. The mean age of the patients was 32.54 ± 13.97 years with the majority being female. The most common cause of disc edema was idiopathic intracranial hypertension (IIH) (37.5%,). Majority of the patients complained of isolated diminution of vision (38.4%). Among the eyes affected, 78.3% had best corrected visual acuity (BCVA) 6/6-6/18, 36.6% had color vision defect and 31.4% had reduced contrast sensitivity. The most common visual field defect was isolated enlarged blind spot (39.7 %). Conclusion: IIH followed by optic neuritis (ON) are the most common causes of disc edema. Conditions with disc edema mainly affect the age group 21-40 years with females affected 2.5 times more than males. Visual acuity, color vision and contrast sensitivity are deranged in majority of cases of ON and normal in majority of cases of IIH.

To report a patient with nonarteritic anterior ischemic optic neuropathy (NA-AION) occurring soon after the COVID-19 vaccination. A 55-year-old woman presented with a 4-day history of inferior visual field disturbance in the right eye 7 days after receiving the first dose of Pfizer-BioNTech COVID-19 vaccine. Examination revealed a best-corrected visual acuity of 20/20 in both eyes. A relative afferent pupillary defect was observed in the right eye. Fundoscopy revealed diffuse optic disc swelling in the right eye, which was prominent above the optic disc. Goldmann visual field testing identified an inferior altitudinal visual field defect with I/2 isopter in the right eye. Although typical complete inferior visual field defect was not detected, a diagnosis of NA-AION was made. The patient was followed without any treatment. During the 2-month follow-up period, the optic disc swelling was gradually improved, and visual acuity was maintained 20/20; however, the optic disc looked diffusely pale in the right eye. Although it is uncertain whether the development of NA-AION after COVID-19 vaccination was consequential or coincidental, we speculate that the close temporal relationship with COVID-19 vaccination suggests the possibility of vasculopathy on the microvascular network of optic nerve head as background of inflammatory or immune-mediated element to the timing of the onset of NA-AION. The aim of this case report is to present this biological plausibility and to elucidate potential ophthalmological complications.

A 69-years-old male patient was treated with amiodarone 200mg/day over the passed two months for atrial fibrillation. He presented a sudden, painless and unilateral visual loss. Ophthalmologic evaluation revealed a bilateral optic disc edema. Neurological examination was otherwise unremarkable. After properly excluding increased intracranial pressure and giant cell arteritis, the main differential diagnosis was between nonarteritic anterior ischemic optic neuropathy and optic neuropathy secondary to amiodarone. The latter diagnosis was favored due to a presence of bilateral and simultaneous optic disc edema, gradual improvement of symptoms after discontinuation of the drug, and, mostly, by persistence of optic disc edema beyond 6 weeks. Of note, an acute presentation of this disorder is common. Amiodarone optic neuropathy is a rare but potentially serious cause of optic nerve dysfunction, and its discontinuation is usually warrant.

Purpose: To report on posterior ischemic optic neuropathies, a vascular disorder that happens in the posterior part of the optic nerve and therefore, usually does not present with optic disc edema. Case Report: This is a case report on a posterior ischemic optic neuropathy with an uncharacteristic presentation. It highlights the importance of understanding the different pathophysiology of PION vs anterior ischemic optic neuropathies in order to help differentiate the two clinically and includes a literature review of posterior ischemic optic neuropathy.

In this article, the results of a study are presented on the influence of the therapeutic retroscleral filling by dispersed “Alloplant” biomaterial upon blood supply and visual functions of the eye. 47 patients (69 eyes) suffering from anterior ischemic optic neuropathy sequelae were examined. Obtained results allowed to study the degree of relationship between the following indices: resistance index of ocular vessels, visual acuity and electrophysiological data, visual field limits. The majority of cases with significant visual fields widening (79 %) correlated with post-operative decrease of resistance index in posterior short ciliary arteries (medial and lateral branches). The results of performed investigation allow to assume that the dispersed “Alloplant” biomaterial use in the treatment of patients with anterior ischemic optic neuropathy sequelae could promote the optic nerve blood supply improvement with further amelioration of visual function indices.
