  • Patent number: 11633101
    Abstract: An apparatus for diagnosis of ocular surface disease includes an electronic tablet with an electronic display and a forward-facing camera. The camera may be placed above the screen when the device is held in landscape mode. A software app executing on the electronic tablet displays a test screen to a patient, the test screen comprising a test image and an alignment indicator. Once alignment is achieved, the patient may read the test image for a period of time, during which blink quality and quantity are tabulated. A video recorded during the test may be reviewed by a physician to confirm or modify blink quality and quantity counts during the test to diagnose ocular surface disease.

  • Publication number: 20230043924
    Abstract: The invention is directed to an eye cover for maintaining eye closure during sleep or for daytime wear for certain eye conditions. The eye cover is sized and shaped so as to fit within the orbit of the patient's eye rather than around the orbit. By fitting closely within the orbit of the eye, the eye cover is much less likely to be disturbed or dislodged during movement over the course of a night's sleep. The eye cover further is porous and includes fenestrations to provide for the passage of air to the eye.
