Background: Optic disc edema is swelling of intraocular portion of the optic nerve. Disc edema is an ophthalmoscopic finding defined by unilateral or bilateral swelling of the optic disc. Unilateral disc edema can be inflammatory, ischemic, compressive or infiltrative. It may also be an eye opener for detection of certain systemic diseases. Aim and Objectives: To know the clinical profile of Unilateral Disc Edema. Material and Methodology: This was an observational prospective study conducted in the department of ophthalmology, Dr. Patnam Mahender Reddy Institute of Medical Sciences, Chevella, Hyderabad, for the period of one year. We have included 60 Patients presenting with unilateral disc edema and males and females between the age of 20 -65 years. Results: 60 patients, among them 34(56.7%) of the patients were female and 26(43.3%) of the patients were male, half of the patients were belonged to the age group of 30 – 40 years and mean age of all the patients was 38.56 with standard deviation of 6.42. The commonest cause for unilateral disc edema is non arteritic AION and the next common cause is optic neuritis. it was observed that NAION affects age group between 40 -50 years of age and that of optic neuritis affecting between 20 -30 years of age group. Most common presenting complaint was Diminution of Vision (DOV) in 47 % cases followed by headache in 50 % cases. Conclusion: patients with unilateral disc edema, NAION and optic Neuritis should be considered as first among various diagnosis and these diagnosis are common in age group of 40-50 years of age. Differentiating NAION and optic neuritis is very essential because for each of the diagnosis treatment condition is different.
