To observe the efficacy and safety of modified Snyder–Thompson posterior scleral reinforcement in extensive high myopia of Chinese children. We had a retrospective design, and included a control group of children with natural progression of high myopia.


This study included 64 eyes in 41 Chinese children with extensive high myopia who underwent modified Snyder–Thompson posterior scleral reinforcement surgery (PSR group), and 17 eyes in 11 age- and myopia-matched children who wore spectacles (control group). The mean follow-up was 4.99 ± 1.3 years in the PSR group and 4.48 ± 1.3 years in the control group. Axial length, spherical equivalent (SE), uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA) and fundus examinations were recorded before and after treatment, and complications were noted.


The mean change in SE at the end of the follow-up period was 1.5 ± 1.44 diopters (D) and 3.02 ± 1.57D in the PSR and control groups respectively. These changes were equivalent to an increase in axial length of 1.27 ± 0.54 mm and 2.05 ± 0.91 mm respectively. The PSR group showed less myopic progression and less eye elongation (p < 0.001). A notable increase in UCVA was only found in the PSR group (p = 0.0001). The improvement in BCVA was significantly greater in the PSR group (p = 0.0354). There were no serious complications of PSR surgery.


The modified Snyder–Thompson PSR surgery was effective and safe in controlling extensive high myopia of Chinese children.
