PURPOSE: Transscleral cyclodiode laser cyclophotocoagulation (TSCP) is often reserved for treatment of refractory glaucoma. This retrospective study investigates the safety and efficacy of TSCP among the Chinese population. METHODS: A retrospective review was performed on electronic patient records of all patients receiving TSCP between years 2009 to year 2016. Patient demographics, indication for laser, success and response rate, change in intraocular pressure (IOP), number of treatment sessions, laser energy, glaucoma medication, visual acuity, pain symptoms and complication rate were documented. RESULTS: The study included 126 patients: 81 patients were male and 45 were female, and the mean age was 66.6 ± 14.3 years old and the mean follow-up was 22.7 ± 14.1 months. The mean number of treatment sessions was 1.5 ± 0.8. The success rate was 67.3%. The mean IOP before TSCP was 67 ± 38.6 mmHg and 22.8 ± 14.2 mmHg after TSCP, the mean IOP reduction was 38.4%, which was statistically significant (P value < 0.001, Wilcoxon signed rank test). The mean laser energy used per eye was 72.7 ± 56.6 and 49.2 ± 22.9 J per individual treatment session. The mean number of laser shots was 15.0 ± 6.1. 71% of patients were able to reduce their glaucoma medication after TSCP, (P value < 0.01, Wilcoxon signed rank test). 86.1% of patients had improvement in pain symptoms after TSCP. The overall complication rate was 7.1%. CONCLUSION: TSCP was found to be safe and effective among the Chinese population, with comparably low laser energy setting and complication rate. It was found to be most effective in treatment of glaucoma due to trauma, acute angle closure, uveitis and chronic angle closure.
