NCT ID: NCT05251792 Recruiting - Glaucoma Clinical Trials

Macular Pigment Optical Density in Primary Angle-closure Disease

Start date: November 11, 2021
Phase:
Study type: Observational

Glaucoma is the leading cause of irreversible blindness in the world, and primary angle-closure glaucoma (PACG) is the most important type of glaucoma in Asia. Primary angle closure disease (PACD) is a group of diseases related to PACG, and the pathogenesis is still unclear. Macular pigment has the functions of filtering short-wavelength waves and anti-oxidation, which are related to visual function. Previous studies have found that the macular pigment density (MPOD) is significantly reduced in primary open-angle glaucoma. This project uses the single-wavelength reflection method to measure MPOD, observes the characteristics of PACD and the normal control group's changes in retinal MPOD, and explains the relationship between PACD's MPOD changes and angle-closure glaucoma optic nerve damage
