Neuro-Ophthalmologic Features of Spinocerebellar Ataxia Type 7

Abstract

Based on this study, patients with SCA7 often have visual symptoms that may precede, accompany, or follow the onset of ataxic symptoms. The severity of vision loss and ataxia may be discordant. Ophthalmoscopic evidence of macular abnormalities may be scant, but results of ERG will always be abnormal. This information may assist in earlier and more cost-effective diagnosis and permit more effective patient counseling.
