Summary
Delayed suprachoroidal hemorrhage is rare after pediatric glaucoma surgery. Ahmed valve implantation, especially in aphakic eyes, presents the highest risk for this complication.
Area of Science:
- Ophthalmology
- Pediatric Surgery
Background:
- Delayed suprachoroidal hemorrhage is a rare but serious complication following glaucoma surgery.
- Identifying risk factors is crucial for preventing this adverse event in pediatric patients.
Purpose of the Study:
- To identify surgical risk factors associated with delayed suprachoroidal hemorrhage after glaucoma surgery in children.
Main Methods:
- A retrospective literature review was conducted from 1966 to 2008.
- Pediatric glaucoma surgery outcomes were analyzed, focusing on cases of delayed suprachoroidal hemorrhage.
Main Results:
- Nine cases of delayed suprachoroidal hemorrhage were identified from 2,491 surgeries (0.36%).
- The complication occurred in 1.5% of Ahmed valve implantations (6/389), particularly in aphakic eyes.
- Three cases (0.4%) occurred after trabeculectomy with antimetabolites in aphakic eyes.
Conclusions:
- Delayed suprachoroidal hemorrhage is infrequent in pediatric glaucoma surgery.
- Ahmed valve implantation in aphakic eyes appears to carry the highest risk.
- Intraoperative mitomycin-C use may increase risk after Ahmed valve implantation and should be used cautiously.

01:28Angle Closure Glaucoma: Treatment
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...
01:25Glaucoma: Overview
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...
01:27Open Angle Glaucoma: Treatment
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.
