Effect of posterior scleral reinforcement on pathologic myopia and OCT observation

Abstract

Objective To investigate the clinical merits of pathologic myopia and the effect of posterior scleral reinforcement for the treatment of pathologic myopia.Methods The clinical data of 30 pathologic myopia cases ( 58 eyes) were reviewed.Thirty-seven eyes underwent posterior scleral reinforcement surgery.Main outcome measures included best-corrected visual acuity,refractive error,axial length,fundus changes and surgery complications.Results OCT of eighteen pathologic myopia cases (32 eyes) showed retinoschisis ( 15 eyes),choroidal neovascularization ( 2 eyes),neuroepithelial layer thinner ( 3 eyes).After operations the OCT showed the gap between the inside and outside the splitting of the retinal layers became narrow,split cavity of 9 eyes completely disappears,split cavity of 6 eyes became smaller.Best corrected visual acuity improved significantly after surgeries in the following-up period.Myopic diopters and axial lengths also reduced significantly ( P ＜ 0.05 ).No serious complications were observed.Conclusions ①Macular OCT scan in high myopia for early detection of macular changes to guide treatment have important clinical implications.② Treatment of pathological myopia with posterior scleral reinforcement can stabilize diopters,improve visual function.
