Comparison of viscocanalostomy plus suture‐assisted near‐360‐degree trabeculotomy and viscocanalostomy plus rigid probe trabeculotomy in primary congenital glaucoma

Purpose To compare the efficacy and safety of viscocanalostomy plus near‐360‐degree suture trabeculotomy (VST) with viscocanalostomy plus rigid probe trabeculotomy (VT) in treating primary congenital glaucoma (PCG) over a one‐year follow‐up. Methods This consecutive retrospective study included patients with PCG confirmed within 3 years of age from March 2017 to October 2019. Efficacy was evaluated by comparing the postoperative intraocular pressure (IOP) curve and the success rate at one year after surgery. Safety was assessed by comparing the postoperative complications. The number of anti‐glaucoma agents, horizontal corneal diameter (HCD) and cup‐to‐disc ratio (C/D) of the two surgical methods were also compared. Results Data of 90 eyes from 61 patients were analysed. The baseline parameters of the two groups were similar. The IOP at 12 months after surgery in the VST group was 12.7 ± 4.8 mmHg, while that in the VT group was 15.8 ± 6.5 mmHg. The IOP at 6, 9 and 12 months postoperatively in the VST group was significantly lower than in the VT group (p
