High-resolution retinal imaging for patients with inherited retinal degenerations

Official title: High Resolution Retinal Imaging in Patients With Inherited Retinal Degenerations

Run by University of California, San Francisco · NCT00254605 · Data updated 2026-11-12

This study is testing advanced imaging techniques to see how inherited retinal diseases affect vision and to better understand the changes happening in the retina for people with conditions like retinitis pigmentosa and cone-rod dystrophy.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are individuals diagnosed with inherited retinal degenerations, such as retinitis pigmentosa, who can travel to the study location.

Probably not a fit

Patients with cataracts or irregular corneal astigmatism, as well as those who have undergone prior refractive surgery, may not benefit from this study.

What this trial studies

This observational study aims to investigate the structure and function of the retina in patients with inherited retinal degenerations using advanced imaging techniques such as the Adaptive Optics Scanning Laser Ophthalmoscope (AOSLO) and Optical Coherence Tomography (OCT). By correlating high-resolution images with standard vision measures, the study seeks to enhance understanding of vision loss mechanisms in conditions like retinitis pigmentosa and cone-rod dystrophy. The research will also explore the functionality of individual photoreceptors through a novel technique called microperimetry. Ultimately, the findings could provide valuable insights into the progression of retinal diseases and potential future therapeutic approaches.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding of retinal degenerations, potentially guiding future treatments and interventions.

How similar studies have gone: Other studies utilizing advanced imaging techniques in retinal research have shown promise, suggesting that this approach may yield valuable insights.
