Security and validity of posterior sclera reinforcement for high myopic retinopathy / 眼科新进展

ABSTRACT

Objective To investigate the efficacy of security and validity of posterior sclera reinforcement (PSR) for high myopic retinopathy (MR).Methods This study included 76 eyes in 41 patients with MR who underwent PSR and were followed up for two years.Preoperative and postoperative axial length,best-corrected visual acuity,the reattachment of retinoschisis and the complications were evaluated.Results The axial length was shortened 3 days,1 month,3 months and 6 months after operation compared with preoperation[(27.71 ± 1.60) mm,(28.11 ± 1.62) mm,(28.58 ± 1.80)mm and (29.01 ± 1.92) mm vs.(30.29 ± 2.01) mm],and the difference was statistically significant (all P =0.000).The axial length gradually increased to preoperative level at 1 year after surgery,and there was no significant difference in the postoperative 2-year and preoperative axial length (P =0.300).The best corrected visual acuity was improved 1 month after surgery,but the improvement had no significantly difference compared with the preoperative one (P =0.080).The best corrected visual acuity was improved at 3 months,6 months,1 year and 2 years postoperatively continuously,and the improvement had significantly difference compared with the preoperative ones (all P ＜0.05).In addition,there were 34 eyes with retinoschisis before surgery,and the retina was completely attached postoperatively in 27 eyes (79.41％),almost attachment was observed in 4 eyes (11.76％),and improvement was in 3 eyes (8.82％).No complications occurred during surgery.Conjunctival irritation,high intraocuiar pressure,orbital inflammation,diplopia and visual deformation and macular bleeding recurrence occurred postoperatively and all recovered in 3 months.Conclusion During 2-year follow-up,it is safe and effective for PSR to treat MR,which can control myopic progression effectively in patients with pathological myopia.
