The efficacy of modified posterior scleral reinforcement with round scleral patches in Chinese children with high myopia

Abstract

Purpose To observe the efficacy of modified Snyder-Thompson posterior scleral reinforcement with round scleral patches in Chinese children with high myopia. Methods This retrospective study included 46 Chinese children with high myopia (72 eyes) who underwent modified Snyder-Thompson posterior scleral reinforcement (PSR) with round scleral patches and 43 Chinese children with high myopia (67 eyes) who wore only spectacles as a control group. Both groups attended a follow-up at 3 years. Axial length (AL), spherical equivalent (SE), best-corrected visual acuity (BCVA), and full ocular assessment results were evaluated at the initial and final visits. Complications were recorded. Results AL had increased by 0.29 ± 0.33 mm in the PSR group and 0.82 ± 0.33 mm in the control group (P < 0.0001) at the final follow-up. The change in the SE was 0.31 ± 0.81 D in the PSR group and 2.25 ± 1.02 D in the control group (P < 0.0001). A decrease of 0.02 ± 0.11 LogMAR was found in the control group, and a change of 0.22 ± 0.35 LogMAR was found in the PSR group. No serious complications due to PSR surgery occurred. Conclusions Modified Snyder-Thompson PSR surgery with round scleral patches can effectively limit the progression of axial elongation in Chinese children with high myopia. The operation is safe, causes little damage, and can be customized.
