What this trial studies

This observational study focuses on evaluating the operational feasibility and measurement properties of efficacy endpoints for patients suffering from various retinal degenerations, including Retinitis Pigmentosa and Stargardt Disease. Conducted at the Vision Research and Assessment Institute, the study involves a prospective cohort of up to 40 patients for each condition, who will undergo a series of vision tests over a year. The aim is to understand how well patients utilize their vision in daily activities and to assess the impact of disease progression on their visual capabilities.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with specific retinal degenerations and who have a certain level of visual acuity.

Not a fit: Patients with cognitive impairments or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved methods for assessing vision in patients with retinal degeneration, enhancing their quality of life.

How similar studies have performed: Other studies have shown promise in assessing visual function in similar patient populations, indicating that this approach has potential for success.
