- Phenothiazines and monoamine oxidase inhibitors
- Medications to treat Parkinson's disease
- Family history of narrow angle glaucoma
- Injury to the eye
- Eye drops used to dilate the eyes
- Certain systemic medications
- Developing cataracts
- Severe pain in the eye
- Pupil not reacting to light
- Blurred or cloudy vision
- Sudden vision loss
- Redness and swelling of the eye
- Eye exam
- Tonometry —a test 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—to examine the outflow channels of the angle
- Medications—Eye drops, pills, and sometimes even intravenous drugs are often administered to reduce intraocular pressure.
- Surgery—Surgery may be used to stop or prevent an attack of angle-closure glaucoma. This is usually done by laser.
