Study Summary
The basic objective of this project is to test a modification of existing technology for monitoring the responses of the pupil to light as a method for detecting regional losses of function of the retina. The "instrument" consists of a commercially available set of goggles that monitor the eye positions and pupils using infrared light and small cameras. The signals from the monitoring cameras are collected in a computer that records how their pupils have responded to each lighting condition. Because diabetics develop damage initially to certain parts of the retina before they have more serious damage, the ultimate goal of this research is to develop a simple, noninvasive, rapid method for widespread screening of diabetics in order to identify those who may require medical attention and/or therapy for diabetic retinopathy.
Primary Outcome
We will analyze the following three components of the pupillary response: latency, constriction velocity and amplitude. The measurements will be taken after initiation of the light stimulus. These functions will be determined for each eye of each subject using both the central and annular stimuli. Each set of experimental conditions will yield a unique relative luminance ratio that can be used to compare the relative functional integrity of the peripheral retina with respect to the central macu
Interventions
- DEVICE Pupillometry testing.
