[Trabeculectomy and nonpenetrating surgery in glaucoma]

Area of Science:

• Ophthalmology
• Glaucoma Surgery
• Surgical Techniques

Background:

• Primary open-angle glaucoma (POAG) often requires surgical intervention when medical and laser therapies fail to control intra-ocular pressure (IOP).
• Classical trabeculectomy is a standard surgical procedure for glaucoma, but it carries risks of complications.
• Alternative minimally invasive techniques are being explored to improve safety and efficacy.

Purpose of the Study:

• To compare the efficacy of classical trabeculectomy versus punch and nonpenetrating deep-sclerectomy (NPDS) in managing uncontrolled POAG.
• To evaluate the intra-ocular pressure (IOP) lowering effects and complication rates of these surgical methods.

Main Methods:

• A comparative study involving patients with primary open-angle glaucoma and uncontrolled IOP despite medical/laser treatment.
• Surgical groups included classical trabeculectomy and nonpenetrating deep-sclerectomy (with punch).

Main Results:

• Both classical trabeculectomy and nonpenetrating surgery demonstrated comparable reductions in intra-ocular pressure.
• Nonpenetrating surgery showed a trend towards reduced complications compared to classical trabeculectomy.

Conclusions:

• Nonpenetrating deep-sclerectomy is a promising alternative to classical trabeculectomy for POAG management.
• This technique may offer similar IOP control with an improved safety profile.
