Abstract

The invention relates to the technical field of medical treatment detection and provides a dry eye detection and handheld imaging device and a dry eye detection device and detection method thereof. The dry eye detection and handheld imaging device comprises an eye positioner, a light source, a lens, a camera and a single chip microcomputer. The eye positioner is used for determining the eye position of a person to be examined. When the eye is located at the position of the eye positioner, the light source emits set-shaped light to the eye. The lens and the camera are both fixedly installed with respect to the eye positioner so that the camera can obtain a clear eye image projected by the light source, and the eye image is sent to a PC provided with a dry eye detection unit through the single chip microcomputer. The dry eye detection and handheld imaging device achieves focusing of the camera in advance by arranging the eye positioner, ensures that the lens is located at a fixed position without focusing adjustment, accordingly the size of the device is decreased, and the device can be designed to be the handheld portable device.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a dry eye detection handheld imaging device, dry eye detection equipment and a detection method thereof. Background technique [0002] Dry eye medicine is called corneal xerosis, which is an inflammatory reaction in which the conjunctiva and cornea cannot be moistened. This disease may be an ocular surface disease caused by the lack of water or mucus components in tears or the disorder of the ocular surface protection mechanism. It is one of the ocular surface diseases with the highest incidence in ophthalmology. Surveys in the United States show that 14.6% of the population aged 65 to 84, that is, 4.3 million people, suffer from dry eye, and there is one dry eye patient in five people. It is 17.0% in Japan and 10.3% in Australia. Although there is no clear epidemiological survey result of dry eye in China so far. However, based on China's health conditions and enviro...
