摘要

Background

To observe the safety and efficacy of posterior scleral reinforcement (PSR) with a bovine pericardial patch in patients with progressive high myopia over a 1-year follow-up period.

Methods

Thirteen eyes of 11 patients with progressive high myopia who underwent the PSR surgery were followed up with measurements of axial length (AL), spherical equivalent (SE), best corrected visual acuity (BCVA), and intraocular pressure (IOP) at baseline, 1 and 3 months, and 1 year postoperatively.

Results

The preoperative AL (29.55 ± 1.43 mm) was decreased to 28.95 ± 1.48 mm at 1 month post-PSR surgery and elongated to 29.68 ± 1.45 mm at the end of the follow-ups. The SE decreased from − 15.13 ± 3.43 diopters (D) preoperatively to − 14.43 ± 4.07D at 1 month post-PSR surgery and increased to − 15.25 ± 3.08D at the end of the follow-ups. BCVA remained relatively stable, with no statistically significant differences observed during the 1-year follow-up. The postoperative BCVA improved in eight eyes (62%). No serious postoperative complications were observed.

Conclusions

The modified Snyder-Thompson PSR surgery utilizing a bovine pericardial patch has the potential to delay AL elongation over a one-year postoperative period.
