Abstract

The objective of the study is to collect adaptive optics (AO) retinal images from human subjects with outer retinal diseases (diseases of the outer retina including photoreceptor, retinal pigment epithelium (RPE), basement membrane or choroidal pathologies) to develop new diagnostic methods, biomarkers, and clinical endpoints. Study Population: Up to fifty (50) healthy volunteers without eye disease (Cohort 1) and up to fifty (50) affected participants with any type of outer retinal disease (Cohort 2) will be enrolled. Design: This is a longitudinal study protocol where participants will be imaged with an investigational multimodal AO (mAO) retinal imaging system that includes optical coherence tomography (OCT) and scanning laser ophthalmoscopy (SLO) channels over three years. High resolution OCT and SLO videos will be collected while the instrument automatically detects and corrects for image distortion caused by ocular aberrations. In general, videos of different retinal cellular structures will be acquired from several retinal locations using various imaging modes. Outcome Measures: The primary outcomes for this protocol are development of new diagnostic methods and disease biomarkers, investigation of cellular morphological and functional changes due to various outer retinal diseases, and development of new AO clinical endpoints for novel therapies.
