Glaucoma represents a group of eye disorders that cause damage to the optic nerve. Glaucoma is a degenerative eye disease and one of the leading causes of blindness in the United States.
Angle-closure glaucoma is a condition in which the iris in the eye shifts and blocks the exit passageway of the fluid in the front compartment of the eye. This fluid blockage causes a rapid build-up of pressure in the eye.
Angle-closure glaucoma is an emergency condition that requires immediate medical treatment to preserve vision.
