Laser trabeculoplasty I in simple and capsular glaucoma.

Area of Science:

• Ophthalmology
• Glaucoma Research
• Surgical Interventions

Background:

• Glaucoma is a leading cause of irreversible blindness.
• Laser trabeculoplasty (LTP) is a common treatment for open-angle glaucoma.
• Efficacy of LTP in different glaucoma subtypes requires further investigation.

Purpose of the Study:

• To evaluate the long-term effectiveness of laser trabeculoplasty (LTP) in patients with simple and capsular glaucoma.
• To compare the intraocular pressure (IOP) reduction and medication requirements between the two glaucoma types after LTP.

Main Methods:

• Retrospective follow-up of 131 phakic eyes from 109 patients with simple (52 eyes) and capsular (79 eyes) glaucoma.
• Minimum follow-up period of 12 months post-laser trabeculoplasty (LTP).
• Assessment of success rate, intraocular pressure (IOP) reduction, and medication changes.

Main Results:

• Laser trabeculoplasty (LTP) demonstrated comparable efficacy in both simple (65% success) and capsular (68% success) glaucoma.
• Mean IOP reduction was significantly greater in capsular glaucoma (37%) compared to simple glaucoma (22%).
• Medication tapering was possible in 50% of successful responders; IOP reduction remained stable for up to 18 months.

Conclusions:

• Laser trabeculoplasty (LTP) is an effective treatment option for both simple and capsular glaucoma.
• Capsular glaucoma may experience a greater IOP reduction following LTP.
• LTP can lead to reduced medication needs and sustained IOP control in a significant proportion of patients.
