Abstract

Background and Aim: Optic disc swelling is due to arrest or obstruction of axoplasmic flow at the lamina cribrosa.
It may be due to various pathological conditions like ischemia, infiltration, inflammation, compression, metabolic and
toxic damage. In this study, the clinical profile of each case of unilateral disc edema was analysed in relation to age of
presentation, gender, systemic association, risk factor and prognosis.
Material and Methods: The present study was done in the department of ophthalmology, medical college and hospital.
The patients with the unilateral disc edema were included in the study. Visual acuity was measured using Snellen’s acuity
chart and converted to logmar for the purpose of statistical analysis. Intraocular pressure was recorded. Colour vision
was recorded using ishihara chart. Routine blood investigations were done. Radiological imaging was done.
Results: Females are affected more commonly compared to males in the study group. The commonest cause for unilateral
disc edema is nonarteritic AION and the next common cause is optic neuritis. Compressive disc edema, inflammatory disc
edema and neuroretinitis are the other conditions causing unilateral disc edema. In this study 60 % of the persons showed
disc pallor on follow up and 40 % of person showed normal fundus. 66.67 % of patients of NAION had disc pallor on
follow up. MRI BRAIN in NAION showed small vessel ischemic changes in 6.67% of persons which indicates the ischemic
change were also noted in brain.
Conclusion: If a patient with unilateral disc swelling presents to neuroophthalmology clinic, NA-AION and ON should
be considered first in the differential diagnosis. Other causes of disc edema should not be missed.
