Summary
Combined gonioplasty and trabeculoplasty effectively treated chronic angle-closure glaucoma, maintaining lower intraocular pressure and reducing medication needs in most patients for over a year.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Surgical Interventions
Background:
- Chronic angle-closure glaucoma poses a significant risk to vision.
- Effective management strategies are crucial for preserving visual function.
- Distinguishing between appositional and synechial angle closure is key for treatment selection.
Purpose of the Study:
- To evaluate the efficacy and safety of combined gonioplasty and trabeculoplasty for chronic angle-closure glaucoma.
- To assess the long-term outcomes of this combined surgical approach.
- To determine gonioplasty's utility in differentiating angle closure mechanisms.
Main Methods:
- A cohort of 31 eyes from 25 patients with chronic angle-closure glaucoma underwent combined gonioplasty and trabeculoplasty.
- Patient demographics and follow-up duration (3-36 months) were recorded.
- Intraocular pressure (IOP) reduction, medication requirements, and complications were monitored.
Main Results:
- 60-80% of eyes maintained an IOP < 21 mm Hg and/or reduced medication needs.
- Average IOP reduction was 7.9 mm Hg.
- Complications included peripheral anterior synechiae (61%) and permanently increased IOP (6%).
Conclusions:
- Combined gonioplasty and trabeculoplasty is a useful treatment for chronic angle-closure glaucoma.
- The procedure effectively lowers IOP and reduces medication dependence in a majority of patients.
- Gonioplasty aids in differentiating angle closure types, guiding treatment decisions.

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.

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...
