title: Influence of pars plana vitrectomy on macular sensitivity and morphology in patients with branch retinal vein occlusion and serous retinal detachment.
abstract: OBJECTIVE
  To evaluate the influence of serous retinal detachment (SRD) on the outcome of pars plana vitrectomy (PPV) for macular edema in patients with branch retinal vein occlusion (BRVO).
  
  
  METHODS
  In an interventional case series, 20 patients (20 eyes) with BRVO and macular edema underwent PPV, including 12 patients with SRD and eight with cystoid macular edema (CME). Microperimetry of the macular region and optical coherence tomography were performed before and 6 months after PPV.
  
  
  RESULTS
  In both the CME and SRD groups, the mean macular thickness and macular volume decreased significantly from baseline to 3 and 6 months after PPV (all P < .01), while visual acuity improved significantly in both groups (both P < .01). However, mean macular sensitivity only increased significantly in the SRD group (P < .05).
  
  
  CONCLUSIONS
  PPV achieves greater improvement of macular sensitivity in BRVO patients with SRD than in those with CME.
