title: Long-Term Changes of Macular Thickness after Pars Plana Vitrectomy in Optic Disc Pit Maculopathy: A Spectral-Domain Optical Coherence Tomography Study.
abstract: OBJECTIVE
  To evaluate macular thickness (MT) changes, using spectral domain optical coherence tomography (SD-OCT) in patients with optic disc pit (ODP) maculopathy after pars plana vitrectomy (PPV) with or without internal limiting membrane (ILM) peeling.
  
  
  METHODS
  Our retrospective study included nine patients with ODP maculopathy, treated with either PPV (n = 5) or PPV with ILM peeling (n = 4). All participants, who had a mean long-term follow-up of 33.4 ± 7.0 months, underwent a complete ophthalmological examination and SD-OCT. Due to the preoperative macular elevation, the postoperative MT in the operated patients was compared with that of fellow eyes and with normative data.
  
  
  RESULTS
  A significant reduction in MT was noticed in all macular sectors of the operated cases at the last examination. The reduction was more evident in the group of PPV with ILM peeling. At the last examination of the follow-up, there was a statistically significant improvement regarding BCVA in both groups in comparison with baseline, while the two groups did not differ significantly in between (p = 0.245).
  
  
  CONCLUSIONS
  In the long-term follow-up period, our study demonstrated a significant reduction in MT in patients with ODP maculopathy treated with PPV, which was more profound in those cases where PPV included ILM peeling. .
