Anterior Segment Anatomic Parameters for Risk Profiling of Primary Angle-closure Glaucoma

China168 participantsStarted 2022-11-22

Plain-language summary

The goal of this observational study is to examine the anterior segment anatomical parameters associated with the scleral spur and cornea for risk profiling of primary angle-closure glaucoma (PACG). The main question it aims to answer is: • Are there new anatomical parameters of the anterior segment of the eye that can be used early for risk profiling for PACG? Researchers will compare PACG and narrow angle groups to see if there are some anatomical parameters that can distinguish the two.

Inclusion criteria

✓. Primary angle-closure glaucoma （PACG) was defined as an occlusion angle with peripheral anterior synechiae and intraocular pressure (IOP) \> 21 mmHg or associated with glaucomatous optic neuropathy. The following conditions were identified as possible glaucomatous optic neuropathies, including a vertical cup-to-disc ratio ≥ 0.6, vertical cup-to-disc ratio asymmetry ≥ 0.2, optic disc haemorrhage, and visible retinal nerve fibre layer defect.
