Summary
Non-penetrating deep sclerectomy effectively lowers intraocular pressure in open-angle glaucoma patients. While the technique has a learning curve, it offers a safe and efficient surgical option with few complications.
Area of Science:
- Ophthalmology
- Surgical Procedures
- Glaucoma Treatment
Background:
- Open-angle glaucoma requires effective intraocular pressure (IOP) management.
- Medically uncontrolled glaucoma necessitates surgical intervention.
Purpose of the Study:
- To evaluate the short-term efficacy and safety of non-penetrating deep sclerectomy.
- To assess IOP reduction and complication rates following this novel filtering procedure.
Main Methods:
- Retrospective analysis of 29 patients (34 eyes) with medically uncontrolled open-angle glaucoma.
- Surgical technique involved fornix-based conjunctival flap and deep sclerectomy, preserving the trabeculo-descemetic membrane.
- Preoperative and postoperative IOP, visual acuity, and slit-lamp examinations were recorded.
Main Results:
- The non-perforated deep sclerectomy group (25 eyes) showed a mean IOP decrease from 5.64-7.28 mmHg to 15.31-4.28 mmHg.
- Only 2 eyes (IOP > 20 mmHg) experienced treatment failure in the non-perforated group.
- Anterior chamber perforation occurred in 9 eyes during the initial learning period, with rare and transient postoperative complications.
Conclusions:
- Non-penetrating deep sclerectomy is an efficient surgical option for open-angle glaucoma.
- The procedure leads to progressive IOP reduction and a low rate of associated complications.
- Mastering the technique is crucial, as anterior chamber perforation is the primary complication during the learning phase.
