Chronic Closed-angle Glaucoma
Chronic closed-angle glaucoma occurs when the eye’s drainage angle narrows gradually and slowly restricts the ability of the eye to drain fluid. The progression of this is often the same as for open-angle glaucoma.
Acute Closed-angle Glaucoma
Acute closed-angle glaucoma occurs when the iris is not as wide and open as it should be, resulting in a sudden rise in intraocular pressure. Symptoms include severe headaches, nausea, vomiting, and blurred vision. These symptoms are intense and noticeable, and you must get medical attention immediately.
