Clonazepam associated retinopathy.

摘要

PURPOSE: To report a case of retinopathy associated with the longterm intake of the antiepileptic drug clonazepam. METHODS: Case report. RESULTS: A 36-year-old woman, with a history of long-term use of the antiepileptic drug clonazepam developed subtle visual disturbances. Funduscopy revealed areas of mild depigmentation of the retinal pigment epithelium throughout the posterior pole bilaterally corresponding to transmission hyperfluorescence on fluorescein angiography. There was no history of any inherited retinal degenerative disease and no other known agent responsible for retinal toxicity had been used. CONCLUSIONS: The longstanding intake of the antiepileptic drug clonazepam may be associated with the development of toxic retinopathy.
