Comparison of Ultrasound Cycloplasty and Transscleral Cyclophotocoagulation for Refractory Glaucoma in Chinese Population
Abstract Background: To compare the efficacy and safety of focused ultrasound cycloplasty (UCP) and transscleral cyclophotocoagulation (TSCP) in the treatment of refractory glaucoma in Chinese population. Methods: We retrospective compared twenty-eight eligible patients with refractory glaucoma, who were divided into the UCP group and TSCP group. Patients in this two groups underwent a corresponding procedure during June 2018 to February 2019. The intraocular pressure (IOP), visual acuity, use of anti-glaucoma agents and complications were reviewed and compared between the two groups. Results: After the 12-months follow-up, postoperative IOP and number of anti-glaucoma agents, which were used postoperatively in the two groups were both lower than the baseline level, and the differences were statistically significant (P<0.05). There were no significant differences in IOP, number of anti-glaucoma agents and the best-corrected visual acuity between the two groups at each follow-up time point (P>0.05). In terms of complications, the pain at 1d after surgery in the UCP group was significantly milder than that in the TSCP group (P<0.05), while there were no significant differences in other complications between the two groups (P>0.05).Conclusions: Both UCP and TSCP are safe and effective methods for the treatment of refractory glaucoma. Nevertheless, pain is less severe after UCP.
