Observational Study of BEST1 Vitelliform Macular Dystrophy

This study is looking at Best Vitelliform Macular Dystrophy (VMD), an eye condition that can cause vision loss. It's caused by changes in the BEST1 gene. This is an observational study, meaning researchers will watch how the condition progresses naturally over time in people with BEST1 VMD. They want to understand the disease better and find good ways to measure its changes. This information will help develop new treatments in the future. To join, you need to have a diagnosis of BEST1-associated VMD confirmed by a study doctor and be able to attend four follow-up visits over three years. The study aims to enroll 52 participants.

Study design
This is an observational study, meaning no new treatments are being tested. It aims to enroll 52 participants to understand the natural progression of BEST1 VMD.
What's involved
You would need to commit to 4 follow-up study visits over a period of up to 3 years. These visits will include eye exams like Medmont Dark Adapted Chromatic (DAC) Automated Perimeter, Full-field electroretinogram (ERG), and Electroocoulogram (EOG).
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for up to 3 years, with primary measurements taken at these time points.
