Fast Resolution of Bilateral Optic Neuritis Secondary to Multiple Sclerosis after Treatment with Glatiramer Acetate

Purpose: To report a patient with bilateral retro-bulbar optic neuritis (ON) secondary to multiple sclerosis (MS) who responded speedily to glatiramer acetate (GA) subcutaneous injections. Methods: Case report of a 34-year-old patient with multiple sclerosis that presented with bilateral optic neuritis, confirmed clinically and with visual fields. Concomitantly she had active neurological systemic symptoms that prompted the start of GA subcutaneously. Results: Clinical examination with pupillary reflexes, Ishihara test and visual fields pre and post injections revealed a quick recovery of the optic nerve function. Her neurological systemic symptoms improved significantly as well. Conclusion: ON secondary to MS is a frequent diagnosis in neuro-ophthalmology and it can be invalidating and distressing in an already disabled patient. GA is an immuno-modulator currently approved for use in patients with MS. We present a case of bilateral retro-bulbar ON that responded to the use of GA.
