Glaucoma represents a group of eye disorders that may cause damage to the optic nerve due to high intraocular pressure. 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.

The exact cause of narrow-angle glaucoma is unknown. However, factors that play a role in causing the disease include:
- Narrowing of the drainage angle in the eye—Aging and being farsighted are two causes of this narrowing.
- Being born with narrow angles—more common in people who are Asian
- Injury to the eye
Sometimes certain medications can cause sudden angle-closure glaucoma. These include:
- Botulism injections around the eye
- Sulfa-based drugs
- Phenothiazines and monoamine oxidase inhibitors
- Medications to treat Parkinson's disease
