An observational study in Primary Angle Closure Glaucoma, sponsored by Guangfu Dang. Completed at 1 site in China. Open to participants aged 47 Years to 91 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-12-28.
Sponsored by Guangfu Dang · Observational
The goal of this observational study is to discuss the correlation between primary angle-closure glaucoma and the state of the suspended ligament of the lens and the pathogenesis of PACG by measuring the biological data of primary angle-closure glaucoma and observing its anatomical changes.
Patients clinically diagnosed with Primary angle-closure glaucoma (PACG) and normal control patients from December 2020 to January 2022 were enrolled in this study.
From December 2020 to January 2022, patients with primary angle-closure glaucoma and normal control patients were diagnosed for the first time and intended to undergo cataract surgery in the ophthalmology department of the First Affiliated Hospital of Shandong First Medical University (Shandong Qiandfo Hospital).
Exclusion Criteria:
All patients in the experimental group met the diagnostic criteria of primary angle-closure glaucoma in the Chinese Glaucoma Guidelines(2020).
The depth of the anterior chamber is normal, and the whole corner of the chamber is open; The cup-to-plate ratio is less than 0.5; No family history of glaucoma
