title: PHOTORECEPTOR OUTER SEGMENT LENGTH AND OUTER FOVEAL THICKNESS AS FACTORS ASSOCIATED WITH VISUAL OUTCOME AFTER VITRECTOMY FOR VITREOMACULAR TRACTION SYNDROME.
abstract: OBJECTIVE
  To investigate the predictive factors for postoperative best-corrected visual acuity (BCVA) in patients with vitreomacular traction syndrome treated with vitrectomy.
  
  
  METHODS
  The records of 21 patients with 21 eyes that underwent vitrectomy for vitreomacular traction syndrome and followed for at least 12 months were retrospectively reviewed. The BCVA and spectral domain optical coherence tomography findings were investigated preoperatively and at 1, 3, 6, and 12 months postoperatively. Axial length was measured preoperatively. The correlations between 12-month postoperative BCVA and preoperative parameters, including BCVA, age, axial length, central foveal thickness, outer foveal thickness, and photoreceptor outer segment length, were evaluated.
  
  
  RESULTS
  Twelve-month postoperative BCVA was significantly negatively correlated with preoperative outer foveal thickness and photoreceptor outer segment length (outer foveal thickness: P = 0.029, r = -0.501; photoreceptor outer segment length: P = 0.022, r = -0.523, respectively) but not correlated with age, axial length, preoperative BCVA, and preoperative central foveal thickness (age: P = 0.346, r = 0.216; axial length: P = 0.333, r = 0.242; BCVA: P = 0.202, r = 0.290; central foveal thickness: P = 0.065, r = -0.410, respectively).
  
  
  CONCLUSIONS
  Preoperative outer foveal thickness and photoreceptor outer segment length could be good predictive factors of postoperative BCVA in patients with vitreomacular traction syndrome.
