title: Pars plana vitrectomy for vitreo-retinal complications of birdshot chorioretinopathy.
abstract: OBJECTIVE
  To evaluate the anatomical and functional outcomes of pars plana vitrectomy (PPV) in the treatment of vitreoretinal complications of birdshot chorioretinopathy (BCR).
  
  
  METHODS
  The clinical records of 9 consecutive patients (16 eyes) with vitreo retinal complications in BCR refractory to medical therapy who underwent pars plana vitrectomy were reviewed.
  
  
  RESULTS
  Indications for PPV were macular edema in 9 eyes (56.2%), and persistent vitreous opacities in 7 (43.8%). At a mean postoperative follow-up of 44.1 months, best-corrected visual acuity improved ≥2 Snellen lines in 9 eyes (56.2%), remained stable in 6 (37.5%) and worsened in 1 eye (11.1%). Systemic medication was significatively reduced after surgery (p = .020) and macular thickness on optical coherence tomography exams decreased significatively in eyes with macular edema (p= .0039).
  
  
  CONCLUSIONS
  In this small series of eyes with limited follow-up PPV seems to be a safe and effective for treatment of vitreoretinal complications in patients with BCR.
