Abstract
A detection device for detecting ocular disease and abnormalities in human yes. The ocular disease and abnormality detection device includes a photo-imaging device having a lens aligned on a selected optical axis. A flash unit generates a flash beam of light generally along the optical axis to produce retinal reflections from a patient's eyes. The retinal reflections from the patient's eyes are recorded by the photo-imaging device and displayed on a video display screen. A beamsplitter is positioned on the optical axis to pass the flash beam of light from the flash device to the patient's eyes, and to pass the retinal reflection from the patient's eyes to the photo-imaging device. A visual image is projected on a surface of the beamsplitter which appears to the patient's eyes as being positioned on the optical axis and generally superimposed on the lens of the photo-imaging device. The patient's eyes generally focus on the lens of the photo-imaging device as the patient views the projected image. A separate camera and video display is provided to monitor the patient's face. Patient information is preferably recorded with the retinal reflections from the patient's eyes. Methods of detecting ocular disease and abnormalities are also disclosed.
