New study sheds light on vision loss in rare genetic brain disorders

This study looks at how spinocerebellar ataxia (SCA) affects the eyes and vision. Researchers will examine 60 adults with SCA types 1, 2, 3, or 27B, including those with early symptoms and those who are not yet symptomatic. The goal is to measure vision changes and eye damage using tests like eye exams and scans, helping to better understand these rare neurological diseases.
