What is angle-closure glaucoma?
Angle-closure glaucoma occurs when the iris and cornea are too close and block the flow of fluid into the anterior chamber angle of the eye, often leading to increased pressure inside the eye. It can develop slowly over time, but symptoms often occur suddenly in what is sometimes called an 'acute attack'. Symptoms can include a red, painful eye, blurred vision and glare sensitivity. Without treatment, an acute attack of angle-closure glaucoma can lead to severe, irreversible vision loss within days.
