Purposess: To evaluate the effectiveness of lowering intraocular pressure and the safety of Micropulse Transscleral diode laser cyclophotocoagulation (MP-TSCPC) with a duty cycle of 31,3% in absolute glaucoma patients.
Methods: A prospective interventional study was performed on 64 eyes from October 2020 to April 2021 at the Ho Chi Minh City Eye Hospital.
Results: Sixty four patients including 26 females and 38 males were recruited with the mean age 56.1±2.1. The mean IOP at pre- and post-opereration was 45.9±11.0 and 25.8±13.8mmHg, respectively. The average IOP reduced 42.4%, 33.5%, 39.1% and 45.5% from baseline after surgery at 1 week, 1 month, 3 months and 6 months (p value <0,001). 93,7% of patients improved pain symptoms after MP-TSCPC. The mean number of antiglaucoma medication was down from 3.5 ± 0.69 at the begining to 1.6 ± 0.78 at the end of the study. No serious complications were recorded.
Conclusion: Micropulse Transscleral diode laser cyclophotocoagulation with a duty cycle of 31,3% is an effective and safe method to lower intraocular pressure and relieve pain in absolute glaucoma.
