What this Trial Is About

Researchers are studying adaptive optics, a new imaging technology, to improve the diagnosis, treatment, and management of eye diseases affecting the retina. The study involves both people over age 12 with various eye diseases and healthy volunteers over age 12 to compare retinal images between diseased and normal eyes. The goal is to find better ways to detect retinal problems earlier than current methods allow. Participants will undergo eye exams including pupil dilation and adaptive optics imaging, where they look into a special instrument that captures high-resolution images of the retina. Some may also have additional tests like perimetry, color vision tests, and electroretinograms using numbing eye drops and special contact lenses. This observational study plans to enroll a total of 600 participants over five years, with 350 having eye diseases and 250 healthy volunteers. During the study visits, participants will provide medical and eye history and information about their medications. Researchers will assess the adaptive optics images qualitatively and quantitatively to compare normal and diseased retinal states. The study includes regular eye exams and imaging assessments, with the primary outcome focused on evaluating these adaptive optics images. Participation involves one or more visits, with detailed eye examinations and imaging procedures to monitor retinal health.
