Long-term efficacy of posterior scleral reinforcement for maculoschisis in high myopia

Objective To evaluate long-term efficacy of posterior scleral reinforcement for the treatment of maculoschisis in high myopic eyes. Methods The data of 37 eyes of 30 cases with maculoschisis in high myopia eyes were collected and analyzed retrospectively, they underwent scleral reinforcement with allodural or allogeneic sclera, and the followed-up time was 5 years. Results After surgery, all cases were examined with optical coherence tomography(OCT). The splitting cavity of retina disappeared in 33 eyes(89.2%). The splitting wasn’t improved in 2 eyes. The macular hole occurred in 2 eyes. After surgery, the refractive degree was lower, and the difference was statistically significant(χ2=47.910, P=0.000). The best corrected visual acuity (BCVA) were improved after surgery, and the difference was statistically significant(t=5.034, P=0.011). The mean length of the ocular axis in patients before surgery was (29.42±2.67) mm. After 6 months, 1, 3 and 5 years, the length of axis were respectively: (28.21±1.87)mm, (28.63±1.62)mm, (29.16±2.15)mm and (29.31±2.42)mm. Conclusion Posterior scleral reinforcement surgery in the treatment of high myopia and maculoschisis is effective , it can stable eye axis and improve visual acuity.
