title: SCLERAL IMBRICATION COMBINED WITH PARS PLANA VITRECTOMY WITHOUT INTERNAL LIMITING MEMBRANE PEELING FOR MYOPIC SCHISIS.
abstract: OBJECTIVE
  We investigated whether scleral imbrication combined with pars plana vitrectomy without internal limiting membrane peeling would be effective in treating eyes with myopic macular schisis.
  
  
  METHODS
  In this retrospective, interventional case series, 8 eyes of 8 patients with myopic retinoschisis without a macular hole were studied. Scleral imbrication was done with 6-mm-wide mattress sutures placed at the temporal quadrants. Pars plana vitrectomy and removal of the vitreous cortex were performed, but the internal limiting membrane was not removed. The best-corrected visual acuity was measured, and the retinal morphology was determined by spectral-domain optical coherence tomography before and at 6 and 12 months postoperatively.
  
  
  RESULTS
  The mean age of the subjects was 67.1 years. The best-corrected visual acuity improved from 0.71 ± 0.25 to 0.36 ± 0.19 logarithm of the minimum angle of resolution units (Snellen equivalent: from 20/100 to 20/50) at 12 months (P = 0.028). The axial length was shortened from 29.5 ± 1.7 to 28.5 ± 2.5 at 12 months (P = 0.012). The central foveal thickness decreased from 540 ± 171 μm to 170 ± 85 μm at 12 months (P = 0.012). In the 6 macular-detached eyes, 5 eyes (83%) had a complete resolution. The curvature of posterior eye wall was flatter at 12 months (P = 0.049). No retinal complications were observed.
  
  
  CONCLUSIONS
  Scleral imbrication combined with pars plana vitrectomy can be an effective method of treating myopic schisis.
