Iris biomechanics and sex differences in primary angle-closure glaucoma

Official title: The role of iris biomechanics and sex differences in primary angle-closure glaucoma

Funded at University of South Florida · NIH-11394784 · Data updated 2026-11-12

This project looks at how the eye’s iris biomechanics and sex differences may contribute to angle-closure glaucoma and how this could affect risk and progression.

Who could benefit from this research

Could help

Ideal participants are adults at risk for or with a history of primary angle-closure glaucoma, and healthy controls for comparison.

Less likely to help

People without access to eye care or those outside the study’s eligibility may not benefit.

What this research studies

The study focuses on how the stiffness and behavior of the iris during light-triggered pupil responses may relate to angle-closure glaucoma, which can threaten vision. Researchers will study iris biomechanics in people with PACG and compare them to those without the condition to understand potential mechanisms. The findings could help identify new risk factors beyond anatomy and inform future strategies to prevent vision loss from PACG.

Why it matters

Potential benefit: A better understanding of iris biomechanics could lead to earlier risk detection and new approaches to prevent vision loss in PACG.

How similar studies have gone: Prior work suggests iris stiffness differs in PACG patients, supporting the potential for meaningful insights from this approach.
