Summary
Goniotrepanation as a second surgery can improve intraocular pressure control, though results may be less effective than primary operations. Creating a large intrascleral space is key for successful filtration and long-term pressure regulation.
Area of Science:
- Ophthalmology
- Surgical Procedures
Context:
- Goniotrepanation is a surgical procedure for glaucoma management.
- This study investigates goniotrepanation as a secondary intervention following a failed fistulizing operation.
Purpose:
- To evaluate the efficacy of goniotrepanation as a second surgical procedure for glaucoma.
- To assess the long-term pressure regulation and bleb formation after goniotrepanation.
Summary:
- Goniotrepanation was performed in 70 eyes as a repeat surgery. Tenon removal was done concurrently in cases of bleb scarring. Long-term pressure regulation was diminished compared to primary surgery, with 88% compensated after 4-6 years, but only 35% without additional therapy.
- The creation of a large intrascleral space, facilitated by a large, thin scleral flap, appears crucial for pressure regulation, despite a slightly increased risk of complications.
Impact:
- The study highlights the importance of surgical technique in maximizing intrascleral space for effective glaucoma control.
- Findings suggest that while secondary goniotrepanation can be effective, careful surgical planning is necessary to optimize outcomes and manage potential complications.
