Micropulse laser trabeculoplasty for open-angle glaucoma

Purpose The aim of this study was to evaluate the pressure-lowering effect of 577 nm micropulse laser trabeculoplasty in eyes treated for primary open-angle glaucoma. Patients and methods This prospective interventional case series included 30 eyes of 30 patients treated for primary open-angle glaucoma (one eye of each patient). Treatment was delivered using the IQ 577 nm laser system with fixed treatment parameters: 577-nm (yellow) wavelength, 300-µm spot size, 300-ms envelope duration using 1000 mW of power at a 15% duty cycle, and delivering confluent applications for 360°. Results The mean intraocular pressure at baseline was 18.07±1.91 mmHg. There was a prompt and significant decrease in intraocular pressure that was maintained during the 6-month follow-up, reaching 14.17±1.56 mmHg (P<0.0001). Conclusion Five-hundred and seventy-seven nanometer micropulse laser trabeculoplasty offers a safe, effective adjuvant treatment to pharmacotherapy in treating primary open-angle glaucoma.
