Abstract Purpose:To evaluate the clinical outcomes of micropulse transscleral cyclophotocoagulation(MP-CPC) in patients with glaucoma.

Methods:This retrospective study included 37 eyes treated with initial MP-CPC at Nagoya City University Hospital between January 2019, and December 2022, with a minimum follow-up of 6 months. Data on glaucoma type, intraocular pressure(IOP), antiglaucoma medication scores, and additional surgical interventions were collected and analyzed.

Results:The mean age of patients was 75.1 years, and the mean baseline IOP was 21.7 mmHg. The diagnoses included primary open angle glaucoma(17 eyes), normal tension glaucoma(2 eyes), pseudoexfoliation glaucoma(5 eyes), neovascular glaucoma(3 eyes), and secondary glaucoma(10 eyes). The baseline medication score was 5.3, and 19 patients were taking oral carbonic anhydrase inhibitors(CAIs). Among the 25 eyes(68%) that did not undergo additional surgeries including the second MP-CPC session within 6 months, postoperative IOP was significantly lowered at all time points:14.7 mmHg at 1 month, 14.8 mmHg at 3 months, and 15.6 mmHg at 6 months(all p<0.01). The IOP reduction rates were 25.2%, 26.8%, and 19.7% at, 1, 3, and 6 months, respectively. The antiglaucoma medication score was significantly reduced to 4.8 at 3 months and 4.8 at 6 month postoperatively(p<0.05). The number of patients on oral CAIs decreased significantly from 15 at baseline to three at 3 month and two at 6 months postoperatively(p<0.001). Of 12 eyes(32%) that required additional treatment, five eyes underwent reintervention within the first month.

Conclusions:MP-CPC appears to have the potential to lower IOP and possibly reduce the use of antiglaucoma medications, suggesting its potential as a viable treatment option for glaucoma.
