ABSTRACT
Ethambutol (EMB) is one of the first-line drugs in the treatment of tuberculosis. Ethambutol-induced optic neuropathy (EON) is a very well known side effect which is either dose or duration related. The ocular manifestations of EON include painless loss of central vision and cecocentral scotomas in the visual field. We report a rare case of EMB-induced optic neuritis in a 19 year old female, who was on ATT for spinal tuberculosis for 3 months. Patient presented with painless diminution of vision in both eyes for 15 days which was not improving on refraction. Patient was diagnosed as a case of EON on series of ophthalmic examination and ethambutol was stopped immediately. Patient was given some neurotrophic drugs for 1 month. After 1 month, patient had BCVA of 6/9 in both eyes. Fundus and visual fields were also within normal limits except mild temporal disc pallor.
