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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
