Acute angle-closure glaucoma is caused by a rapid or sudden increase in intraocular pressure (IOP), the pressure inside the eye.
If the angle closes suddenly, symptoms are severe and dramatic. Immediate treatment is essential to prevent optic nerve damage and vision loss. If the angle closes intermittently or gradually, angle-closure glaucoma may be confused with chronic open-angle glaucoma, another type of glaucoma.
