title: METAMORPHOPSIA AND OUTER RETINAL MORPHOLOGIC CHANGES AFTER SUCCESSFUL VITRECTOMY SURGERY FOR MACULA-OFF RHEGMATOGENOUS RETINAL DETACHMENT.
abstract: OBJECTIVE
  To evaluate the correlation between metamorphopsia and outer retinal morphologic changes after successful vitrectomy for rhegmatogenous retinal detachment (RRD).
  
  
  METHODS
  Forty eyes from 40 patients with macula-off (26 eyes) or macula-on (14 eyes) RRDs that underwent pars plana vitrectomy were included. Metamorphopsia was quantified with M-CHARTS. The relationship between the integrity of the outer retinal layers examined by spectral domain optical coherence tomography and metamorphopsia at 6 and 12 months postoperatively was evaluated.
  
  
  RESULTS
  Metamorphopsia was significantly more frequent in eyes with macula-off RRD (88%) than in eyes with macula-on RRD (21%) at 6 months postoperatively (P < 0.001) and became significantly less frequent in macula-off RRD eyes from 6 months to 12 months (64%) postoperatively (P = 0.041). Horizontal metamorphopsia scores in eyes with continuous interdigitation zone and ellipsoid zone bands were significantly smaller than in eyes with a disrupted interdigitation zone band and a continuous ellipsoid zone band or in eyes with disrupted ellipsoid zone and interdigitation zone bands (P = 0.003 and P <0.001, respectively), which was consistent with the results of vertical metamorphopsia scores.
  
  
  CONCLUSIONS
  Restoration of both the ellipsoid zone and interdigitation zone bands seems to be an important factor for the reduction of metamorphopsia after successful vitrectomy for macula-off RRD.
