Patients with angle closure glaucoma may first notice intermittent headaches, eye pain, and halos around lights. Alternatively, they may have an acute angle closure attack, which is accompanied by severe eye pain, headache, blurry vision, and sometimes even nausea and vomiting. An angle closure attack is a medical emergency and a patient should report to an emergency room or their glaucoma specialist immediately for appropriate treatment.
What is angle closure glaucoma?
Glaucoma comprises a group of diseases that cause damage to the optic nerve within the eye. While eyes with open angle glaucoma have a drainage angle that appears anatomically normal, eyes with angle-closure glaucoma have a drainage angle that is blocked. This leads to elevated eye pressure, which causes damage to the optic nerve.
The following are signs of intermittent angle closure. If you or a loved one experiences one or more of the following symptoms, please see a glaucoma specialist as soon as possible.
- Blurry or unfocused field of vision
- Difficulty adjusting to dark rooms
- Recurring mild pain around or in eyes
