title: Entry-site-related retinal detachment after pars plana vitrectomy.
abstract: OBJECTIVE
  Today, pars plana vitrectomy represents a standard surgical procedure for a number of retinal diseases that were previously considered inoperable. The aim of the present study is to investigate the entry site of pars plana vitrectomy as a possible source of retinal detachment.
  
  
  METHODS
  We reviewed retrospectively all cases of uncomplicated pars plana vitectomies because of macular hole, macular pucker and diabetic macular oedema performed in our department between 1 January 2001 and 7 July 2004.
  
  
  RESULTS
  Over 3.5 years, 244 pars plana vitrectomies because of macular disease were performed. Sclerotomy-related retinal detachment was observed in 11 (4.5%) cases. These retinal detachments occurred at a mean of 37 (2-100) days after surgery. They appeared within the first 4 weeks in 55% of the cases.
  
  
  CONCLUSIONS
  Iatrogenic retinal breaks and detachment continue to be a severe complication of pars plana vitrectomy, despite improvements in instrumentation and surgical techniques. A 4.5% incidence of sclerotomy-related retinal detachment after simple vitrectomy calls for action. Current approaches to reduce this complication - such as circular peripheral cryoretinopexy, scleral buckling or 360 degrees laser treatment - are invasive. We recommend extended vitreous base cleaning with scleral indentation and examination of the entry sites, performed with a three-mirror lens or via careful indirect ophthalmoscopy into the periphery, 4 weeks after surgery.
