Dark Adaptometry Protocols for the Diagnosys Espion3

Brief description of study

Adult patients who have already undergone dilation during their routine clinical appointments at the NYU Langone Faculty Group practice will be asked to volunteer to participate in the study. Patients will only be approached by study personnel if they have already been dilated by their retina specialist.The purpose of this study is to determine the parameters which best reproduce standard dark-adaptation curves on the Espion3 instrument. Each exam produces an adaptation curve – which means the device will provide flashes of bright light to total darkness over a period of time. The study will be measuring and examining the quality and quantity features of these adaptation curves. This device has not been approved by the US Food and Drug Administration. For this reason, it is considered an investigational device.
