Visual field status in the management of chronic angle-closure glaucoma

Area of Science:

• Ophthalmology
• Glaucoma Research
• Surgical Interventions

Background:

• Chronic angle-closure glaucoma is a significant cause of vision loss.
• Understanding the efficacy of different surgical interventions based on disease severity is crucial.

Purpose of the Study:

• To evaluate the success rates of peripheral iridectomy and trabeculectomy in chronic angle-closure glaucoma.
• To determine if visual field status influences surgical outcomes.

Main Methods:

• Retrospective analysis of 40 patients with chronic angle-closure glaucoma.
• Categorization of eyes based on presence or absence of visual field loss.
• Comparison of surgical success rates between peripheral iridectomy and trabeculectomy.

Main Results:

• Peripheral iridectomy was highly successful in eyes without visual field loss.
• Trabeculectomy achieved a 93% success rate in eyes with visual field loss, significantly outperforming iridectomy (64%).

Conclusions:

• Surgical management for chronic angle-closure glaucoma should consider the patient's visual field status.
• Trabeculectomy is a more effective treatment for eyes with established visual field loss.
