Laser trabeculoplasty as primary therapy in chronic open angle glaucoma

Area of Science:

• Ophthalmology
• Glaucoma Research
• Laser Therapy

Background:

• Open-angle glaucoma is a leading cause of irreversible blindness.
• Early intervention is crucial for managing intraocular pressure (IOP) and preventing optic nerve damage.
• Laser trabeculoplasty (LTP) is a common treatment modality for glaucoma.

Purpose of the Study:

• To evaluate the efficacy and safety of laser trabeculoplasty (LTP) as a primary therapy for early simple or capsular open-angle glaucoma.
• To assess the long-term intraocular pressure (IOP) control and need for medical intervention after LTP.

Main Methods:

• Retrospective follow-up of 63 phakic eyes from 54 patients with early open-angle glaucoma treated with LTP.
• Monitoring of intraocular pressure (IOP) and need for medication at 12 and 18 months post-LTP.
• Assessment of optic disc and visual field progression.

Main Results:

• 59 of 63 eyes (93.6%) maintained IOP below 22 mmHg at 12 months without medication.
• 46 of 52 eyes (88.5%) maintained IOP below 22 mmHg at 18 months without medication.
• Mean IOP reduction was 28% for simple and 37% for capsular glaucoma at 18 months.
• Only 6 eyes required medical therapy due to progression; no severe complications were observed.

Conclusions:

• Laser trabeculoplasty (LTP) demonstrates significant efficacy in reducing IOP for early open-angle glaucoma.
• LTP serves as a safe and effective primary treatment option, potentially delaying or eliminating the need for medication.
• Long-term IOP control and monitoring for progression are essential after LTP treatment.
