Question: What are some risk factors for closed-angle glaucoma?

Answer: Closed-angle glaucoma occurs when the iris bows forward (typically from pupillary block and a pressure increase behind the iris). Risk factors include:

• Older age
• Family history of acute glaucoma
• Small eyes with crowded anterior segment (including far-sightedness)
• Use of medications that dilate the pupil
• A prior attack of angle-closure in the fellow eye
