Narrow anterior chamber angles often result from the natural position of the iris and lens. Age-related lens thickening can push the iris forward, decreasing space in the angle. Some people are born with smaller eyes that naturally have narrower angles. These structural features increase the risk of angle-closure glaucoma.

Inflammation, swelling, or certain medicines can temporarily change angle width. An eye exam with gonioscopy accurately assesses the angle. Monitoring helps prevent pressure spikes and complications.
Yes, lens thickening with age often reduces angle width.
Some people naturally have narrow angles based on eye structure.
Iris or lens swelling can temporarily narrow the angle.
Many people have no symptoms until pressure rises.
Genetic anatomy, age-related lens thickening and hyperopia can cause shallow anterior chambers and narrow angles. Certain ethnic groups (e.g., Asian populations) are at higher risk.
When the angle between the cornea and iris is narrow, the drainage of aqueous humor through the trabecular meshwork can be blocked, leading to sudden increases in eye pressure known as angle-closure glaucoma.
Treatment may include laser peripheral iridotomy to create an alternate pathway for fluid or lens extraction. Regular eye exams can detect narrow angles early.
