Summary
Trabeculectomy effectively regulated intraocular pressure (IOP) in both exfoliation and simplex glaucoma patients. Visual field preservation was similar, though IOP control was slightly better in exfoliation glaucoma.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Surgical Outcomes
Background:
- Exfoliation glaucoma and simplex glaucoma are distinct forms of open-angle glaucoma.
- Primary trabeculectomy is a common surgical intervention for glaucoma management.
- Understanding long-term outcomes is crucial for patient care.
Purpose of the Study:
- To compare intraocular pressure (IOP) regulation after primary trabeculectomy in exfoliation glaucoma versus simplex glaucoma.
- To evaluate visual field survival and complication patterns in both glaucoma types post-trabeculectomy.
Main Methods:
- Prospective analysis of 95 patients undergoing primary trabeculectomy.
- Assessment of postoperative IOP control and complications over a mean follow-up of 46 months.
- Visual field survival evaluated using high pass resolution perimetry (HRP) in 28 patients.
Main Results:
- Medical treatment was reinstituted in 42% of exfoliation and 36% of simplex glaucoma cases.
- Mean IOP at follow-up was significantly lower in exfoliation glaucoma patients with controlled IOP.
- Visual field deterioration and complication patterns were comparable between the two glaucoma types.
Conclusions:
- Primary trabeculectomy demonstrated good IOP regulation for both exfoliation and simplex glaucoma.
- Exfoliation glaucoma showed a slightly better IOP-lowering effect post-trabeculectomy.
- Visual field preservation was similar across both glaucoma types, irrespective of IOP magnitude.
