Aadithya K. R. | Dr. Rehna Rasheed
Abstract: Background: Optic neuritis is a common clinical manifestation of central nervous system inflammation. Depending on the etiology, visual prognosis and the risk for recurrent injury may vary. Rapid and accurate diagnosis of optic neuritis may be critical for limiting vision loss, future neurologic disability, and organ damage. Methods: 45 patients were taken for the study. Patients with optic neuritis who consulted in Ophthalmology Department were obtained from electronic medical records. Data taken including age, sex, visual acuity and cause were assessed. Results: In our study of 45 patients, 33 (72.3%) were female and 12 (2.7%) were male. The mean age of those with optic neuritis was 36.91 ? 17.201. The mean BCVA of the affected eye was 0.30 ? 0.6, and the mean BCVA of the other eye was 0.0861 ? 0.41286. 20 (30%) patients were affected binocularly .43 were idiopathic, 8 were diagnosed with MOG, 4 patients were MS, 2 were Neuromyelitis Optica(NMO) and 1 patient were diagnosed with chronic relapsing inflammatory optic neuropathy(CRION) and infective. Most of the persons, 17 (26 %) were in the age group 31-40 years.17 patients had done the test in which most of the persons,4(23.52%) had central scotoma. Retrobulbar (60% eyes) was more common than Papillitis (40 % of eyes).26 of the 65 eyes (40 %) recovered visual acuity 20/20 or better. Conclusion: Most common cause of optic neuritis in our study was idiopathic. Optic neuritis was found to mainly affect in 31 ? 40 age group, females were more affected.. Central scotoma was the most common visual defect in optic neuritis. Diabetes mellitus was the associated co morbidity in optic neuritis. Visual prognosis of optic neuritis at 1 month is good in optic neuritis. There was significant improvement in visual acuity at 1 month. In our study Retrobulbar neuritis was more than Papillitis.
