ABSTRACT:
A stereo HMD with an in-dwelling video camera at a patient site, and a stereo camera at a doctor's site are provided for performing examinations of a patient's eyes over a video link. The patient wears the stereo HMD with cameras. Over the video link, images of the patient's eyes are sent to the doctor. The doctor is positioned in front of a stereo camera and an image of the doctor is sent back to the patient for display on the HMD. The doctor can view the external eye structures and can direct the patient to look in various directions. The doctor may move an object in the direction desired. The doctor views the response on a monitor. The doctor may control light to each eye of the patient by covering the appropriate lens of the stereo camera. By alternately covering left and right cameras, the "swinging flashlight" test can be done. Slit light sources built into the HMD are provided to illuminate the front portions of the eyeball, i.e., the anterior chamber, for examination.
