Summary
Persistent fixed dilated pupils after anterior uveitis, especially with human leukocyte antigen B27 (HLA-B27) association, is rare. This case highlights the Urrets-Zavalia-like syndrome, potentially linked to anterior segment ischemia.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
Background:
- Persistent fixed dilated pupils are an uncommon complication following anterior uveitis.
- This is particularly unusual in patients with human leukocyte antigen B27 (HLA-B27)-associated uveitis.
- The Urrets-Zavalia-like syndrome, involving anterior segment ischemia, is the proposed mechanism.

Glaucoma: Overview
1.3K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment
1.2K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Open Angle Glaucoma: Treatment
963
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
