What condition is often associated with primary angle closure glaucoma?

Primary angle closure glaucoma is primarily associated with goniodysgenesis, a condition characterized by an abnormal development of the eye's drainage angle. This anatomical defect results in a narrowed or closed angle between the iris and cornea, which impedes the outflow of aqueous humor, leading to increased intraocular pressure. In primary angle closure glaucomas, the angle can suddenly close, resulting in acute symptoms like severe eye pain, headache, nausea, and blurred vision.

Recognizing this association with goniodysgenesis is crucial for understanding the underpinnings of angle closure glaucoma. It highlights the importance of thorough ocular examinations in at-risk populations, typically individuals with anatomical variants predisposed to angle closure. Understanding this relationship assists in selecting the appropriate treatment and management strategies for these patients.

While conditions like retinal detachment, anterior uveitis, or cataracts may co-occur with various forms of glaucoma, they are not direct contributors to the primary angle closure mechanism itself.
