Anti-Tubercular Therapy Induced Optic Neuritis: A Case Report

Optic neuritis is a rare but serious complication of anti-tubercular therapy (ATT), particularly associated with ethambutol. This case report describes a 32-year-old female who developed bilateral optic neuritis two months after initiating ATT for pulmonary tuberculosis. The patient presented with sudden onset of blurred vision in both eyes. Prompt recognition of the condition, immediate discontinuation of ethambutol, and appropriate management led to significant visual recovery. This case highlights the importance of regular ophthalmological monitoring in patients undergoing ATT and the need for immediate intervention upon suspicion of optic neuritis.
