Closed–angle glaucoma occurs much more quickly. Its rapid onset often causes symptoms such as pain, blurred vision, halos around lights, headache, nausea, and a red eye. The drainage system closes off, thus producing a rapid increase in eye pressure. Closed–angle glaucoma is an emergency eye condition that must be treated quickly or permanent vision loss can result within hours.
Those particularly at risk for closed-angle glaucoma are…
- Far-sighted (hyperopic) patients
- Patients with developing cataracts
