Idiopathy open-angle glaucoma grating-induced eye motion fremitus intermittent display checking apparatus

Abstract

The detection apparatus includes host computer, short afterglow display, printer and eye motion measuring and sampling device. The computer is provided with one functional module to generate intermittent displaying raster stimulating pattern, one eye motion measuring and signal acquiring module, one data processing and outputting functional module and one IDG-OKN eye motion data library. The intermittent displaying raster is used to stimulate the eye under measurement and the induced nystagmus reaction is used in judging whether the testee is suffering from eye diseases. The present invention can detect pathological changes of optic nerve macro cell caused by primary open-angle glaucoma.

Description

technical field [0001] The invention relates to a glaucoma detection device, more specifically, a device for detecting optic nerve damage in primary open-angle glaucoma. Background technique [0002] Glaucoma is a general term for a group of common clinical optic nerve damage eye diseases. According to clinical statistics, it has become the second leading cause of blindness after cataract. Therefore, the diagnosis and condition monitoring of glaucoma are very important. In particular, Primary Open-Angle Glaucoma (POAG) is the most common type of glaucoma, but its onset is slow and difficult to diagnose in the early stage, often leading to blindness in patients. [0003] However, the main instruments currently clinically used for glaucoma detection are tonometers and perimetry, and they all have defects. [0004] 1. Tonometer [0005] The basic principle of the tonometer to measure the pressure inside the eyeball (ocular pressure) is that the pressure generated by the tonom...

[0015] However, the currently used perimetry also has the following disadvantages: 1) Perimeter detection relies on the subject’s statement, and the reliability of the test results is closely related to the subject’s cooperation and familiarity with the test; 2 ) The design of the currently used perimetry does not take into account the characteristics of glaucoma damage to the optic nerve, so studies have shown that in glaucoma, as many as 50% of the optic nerve has been necrotic before the typical visual field defect occurs, and the loss of this part of the optic nerve It cannot be reflected by the detection of the perimetry
