Matching Glaucoma With Impaired Cognition

Overview

Glaucoma is the leading cause of irreversible blindness in the world. The current study is designed to find the underlying relationship between impairment of topological perception and incidence of glaucoma.

Glaucoma is currently the leading cause of irreversible blindness in the world. It has been a difficult task for ophthalmologists and researchers to diagnose glaucoma, especially in early stage. At present, glaucoma diagnosis mainly relies on OCT and visual field test, which have relatively low sensitivity and specificity at the early stage of glaucoma. Previous studies mainly focused on ocular manifestation of glaucoma. However, there was evidence that abnormalities of visual pathway also existed in patients with glaucoma, indicating cerebral cognitive defects may also be involved in glaucoma development. Thus, the current study was designed, in which subjects at high-risk of developing glaucoma are separated into two group based on test results of topological perception. After five years' follow-up, morbidity of primary open-angle glaucoma would be compared between groups to see if there was any relationship between impaired cognitive function and incidence of glaucoma.
