Abstract:
Objective To observe the long-term clinical effect of pars plana vitrectomy combined with fovea-sparing internal limiting peeling in the treatment of macular foveoschisis in pathologic myopic. Methods A prospective case series study. Fifteen patients (15 eyes) with pathological myopic macular foveoschisis who received treatment in Eye Hospital of Wenzhou Medical University from December 2015 to December 2016 were enrolled. There were 4 males (4 eyes) and 11 females (11eyes), with an average age of 55.33±8.34 years. All patients underwent BCVA, diopter, spectral domain OCT and axial length measurement. The mean logMAR BCVA was 0.95±0.64. The mean central fovea thickness (CFT) was 576.00±185.32 μm. All patients underwent vitrectomy combined with fovea-sparing internal limiting peeling. After gas-liquid exchange, 12％ C3F8 was filled and followed up at 1, 3, 6 and 12 months after surgery. Follow-up time was more than 12 months. The structural changes of BCVA and macular area were observed.Results The foveal internal limiting membranes was successfully preserved in all eyes using the techinique. At the final follow-up, the CFT was 258.60±175.22 μm and the BCVA was 0.46±0.43, which were significantly improved compared with preoperative measurements (t=4.90, 5.20;P<0.001). Macular foveoschisis was resovled in 13 eyes. BCVA increased in 14 eyes. Internal limiting membranes proliferation and contraction occurred in 5 eyes and full-thickness macular hole occurred in 1 eye.Conclusions Pars plana vitrectomy with fovea-sparing internal limiting peeling is effective in the treatment of myopic macular retinoschisis. It can improve BCVA and CFT.
