- Narrowing of the drainage angle in the eye—Aging and being farsighted are two causes of this narrowing.
- Being born with narrow angles
- Injury to the eye
- Family history of narrow angle glaucoma
- Glaucoma in one eye—This increases the risk of developing glaucoma in the other eye.
- Ethnic background—Asians are at greater risk of angle-closure glaucoma.
- Injury to the eye
- Eye drops used to dilate the eyes
- Certain systemic medications
- Severe pain in the eye
- Facial pain
- Pupil not reacting to light
- Blurred or cloudy vision
- Redness and swelling of the eye
- Eye exam
- Tonometry —to determine intraocular pressure
- Slit lamp examination—the use of a low-power microscope combined with a high-intensity light source, allows a narrow beam that can be focused to examine the front of the eye
- Gonioscopy—the use of a special mirror to view the drainage angle of the eye
- Medications—Eye drops, pills, and sometimes even intravenous drugs are often administered to reduce intraocular pressure.
- Surgery—Surgery (usually done by laser) may be used to stop or prevent an attack of angle-closure glaucoma.
