Summary
Trabeculectomy effectively preserved vision in advanced glaucoma patients, with significant intraocular pressure reduction. While cataracts impacted visual acuity long-term, no unexplained vision loss occurred.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
- Surgical Outcomes
Background:
- Advanced glaucoma presents significant challenges to vision preservation.
- Trabeculectomy is a common surgical intervention for advanced glaucoma.
- Evaluating long-term visual prognosis and postoperative course is crucial.
Purpose of the Study:
- To assess the visual prognosis and postoperative outcomes in patients with advanced glaucoma following trabeculectomy.
- To compare pre- and postoperative intraocular pressure (IOP), visual acuity (VA), and mean deviation (MD) of visual field tests.
Main Methods:
- Retrospective review of 30 patients with advanced visual field defects undergoing 34 trabeculectomies.
- Defined severe visual field defects using threshold automated perimetry.
- Monitored IOP, VA, and MD, recording complications and long-term outcomes.
Main Results:
- Mean IOP significantly decreased from 28.4 mmHg preoperatively to 14.8 mmHg postoperatively (P=0.001).
- No significant changes were observed in visual acuity (VA) or mean deviation (MD) postoperatively.
- Complications included transient hypotony (5 eyes), late bleb failure (5 eyes), and visually significant cataracts (10 eyes).
Conclusions:
- Trabeculectomy is effective in preserving vision in advanced glaucoma patients.
- Intraocular pressure is largely controllable after surgery.
- Cataract development is a primary factor affecting long-term visual acuity post-trabeculectomy.

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.
