Abstract

Purpose
We evaluated the efficacy and safety of micropulse transscleral cyclophotocoagulation (MP-TSCPC) in refractory glaucoma patients.
Methods
A retrospective chart review was performed for 23 eyes of 23 patients with refractory glaucoma who were followed for 6 months after MP-TSCPC.
Results
The mean preoperative intraocular pressure (IOP) was 39.3 ± 15.8 mmHg and the mean number of antiglaucoma medications was 2.6 ± 0.6. Both significantly decreased at 6 months to 23.8 ± 15.4 mmHg (p = 0.002) and 1.8 ± 1.1 (p = 0.018). Surgical success was defined as a postoperative IOP decrease from 6-21 mmHg or more than 20% reduction from baseline. The success rate was 65.2% at 6 months. Complications of MP-TSCPC included subconjunctival hemorrhage in 6 eyes (26.1%), ocular pain in 16 eyes (69.6%), anterior chamber inflammation in 17 eyes (73.9%), and hypotony in 2 eyes (8.7%).
Conclusions
MP-TSCPC in patients with refractory glaucoma showed a reduction in IOP and the number of antiglaucoma medications in the short-term. However, additional studies are needed to determine the optimal laser settings for maximum efficacy and safety.
