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.
Claims19
A method for diagnosing ocular surface disease in a patient's eyes using an electronic display device executing a software app, the method comprising the steps of:
- a. displaying a first screen to the patient, the first screen comprising an alignment indicator, wherein the alignment indicator comprises a first indicia when the display device is properly aligned with the patient's eyes, and comprises a second indicia when the display device is not properly aligned with the patient's eyes;
- b. displaying a second screen to the patient, the second screen comprising a test material for viewing by the patient;
- c. recording a video of the patient's eyes while the patient is viewing the test material of the second display screen;
- d. using the software app, measuring the quality and quantity of blinks by the patient's eyes while the patient is viewing the test material of the second display screen;
- e. displaying a third display screen to a diagnosing physician, wherein the third display comprises the video of the patient's eyes while viewing the test material of the second display screen.
A method for diagnosing ocular surface disease in a patient, the method comprising the steps of:
- on an electronic device comprising a display screen and a camera, displaying an alignment indicator to the patient;
- using the camera, capturing a video stream of a set of eyes of the patient;
- on the electronic device, displaying the video stream so that the video stream is viewable by the patient;
- using the alignment indicator on the electronic device, providing an alignment signal to the patient indicative of whether the pair of eyes of the patient are aligned with the electronic device;
- after the patient has aligned the electronic device using on the alignment signal, displaying on the display screen a reading passage of text to the patient;
- and
- using the video stream of the set of eyes of the patient, measuring at the electronic device a blink quantity and a blink quality while the patient is reading the reading passage of text.
