SUAREZ-BARAZA, J.  and  SUAREZ-PARRA, S.. Vigabatrin toxic retinopathy. Arch Soc Esp Oftalmol [online]. 2007, vol.82, n.11, pp.711-714. ISSN 0365-6691.

Case report: We report a case of a 63-year-old patient with epilepsy treated with vigabatrin, who was seen because of diminished visual acuity. Examination showed a toxic retinopathy with optic nerve pallor and severely constricted visual fields. One year after cessation of the vigabatrin, no change in the perimetric constriction had occurred. Discussion: Ophthalmologists and neurologists need to be aware of the possibility of retinal toxicity due to the use of vigabatrin. It is still unclear as to which ophthalmogic assessment is of the most diagnostic value; however visual field examination covering the peripheral 60º and optical coherence tomography could be most useful for the screening of patients using this agent.
