primary closed-angle glaucoma

Sunday 20 April 2008

Primary closed-angle glaucoma is caused by sudden blockage of the flow across the pupil. Pressure will rapidly build up in the eye causing pain and redness. Vision becomes blurred and halos are seen around bright objects.

Accompanying symptoms include headache and vomiting. Diagnosis is made from obvious physical findings: pupils dilated, cornea swollen, reduced vision, redness, pain.

Treatment is no longer focused on trabecular or uveoscleral passageways. The formation of fluid can be temporarily treated with carbonic anhydrase inhibitors which act on the ciliary process. But the patient will need surgery or laser treatment.
