title: [Incidence of Postoperative Retinal Detachment after 25-gauge Vitrectomy for Macular Diseases].
abstract: OBJECTIVE
  To examine the rate of postoperative retinal detachment following 25-gauge vitrectomy with extensive peripheral vitreous shaving in eyes with macular diseases.
  
  
  METHODS
  A retrospective non-randomized study of 925 macular surgery cases was undertaken. All surgery was performed using 25-gauge vitrectomy and peripheral vitrectomy was done with scleral indentation. Epiretinal membrane (ERM) surgery (n = 523) and idiopathic macular hole (MH) surgery (n = 402) were performed between June 2005 and January 2014 by one surgeon (H. N.) and all cases were followed up for more than six months. We studied the rate of preexisting posterior vitreous detachment (PVD), endolaser treatment performed for retinal hole/tear and postoperative retinal detachment.
  
  
  RESULTS
  Preexisting PVD was observed in 61.8% of eyes with ERM and in 10.7% of eyes with MH. The rate of endolaser treatment was 41.5% in ERM and 18.0% in MH cases, a statistically significant difference. Postoperative retinal detachment was seen in four of 925 eyes (0.43%) overall.
  
  
  CONCLUSIONS
  Extensive peripheral vitrectomy using scleral indentation reduced the incidence of postoperative detachment occurring after 25-gauge macular surgery.
