简要总结
Current clinical cameras do not allow clinicians to see the cells of the retina. This study will evaluate a new electronic camera's ability to observe the human retina in finer detail.
详细描述
This research study will (1) test the ability of a new electronic camera developed in Dr. Miller's laboratory to observe retina in human subjects, and (2) use the camera for observing disease in the eye. This new camera integrates cutting-edge technologies in adaptive optics (AO) and optical coherence tomography (OCT) that enable the camera to capture sharp images. The objective of our study is to find out (1) whether the AO-OCT camera will allow researchers to observe the retina with finer resolution than current clinical cameras, and (2) whether this finer detail is useful for observing the progression of disease in the eye. To address the second objective, the study will subjects with various disease severity of drusen associated geographic atrophy.

研究组 & 干预措施
Retinal Disease
Subjects with either retinal toxicity or inherited retinal degeneration will undergo multimodal clinical imaging and Adaptive Optics Optical Coherence Tomography (AO-OCT) imaging at each study visit to document regions of disease and healthy retina over time.
干预措施: Adaptive Optics - Optical Coherence Tomography (AO-OCT) retinal imaging
结局指标
主要结局
Quality of photoreceptor and retinal pigment epithelium (RPE) cell layers
时间窗: 2 years
Images of the photoreceptor and RPE cell layers taken with clinical instruments and the AO-OCT will be compared.
Cone Photoreceptor Dysfunction
时间窗: 2 years
Images will be used to determine changes in cone photoreceptor dysfunction and death
RPE cell morphology changes
时间窗: 2 years
Images will be used to determine the changes in RPE cell morphology in regions of healthy and diseased retina (in subjects with retinal disease).
