title: Vitreoretinal surgery for cystoid macular edema associated with retinitis pigmentosa.
abstract: OBJECTIVE
  To evaluate the anatomic and functional outcome of vitreoretinal surgery in eyes with retinitis pigmentosa (RP) and macular edema.
  
  
  METHODS
  Prospective noncomparative case series.
  
  
  METHODS
  Twelve consecutive eyes of eight patients with RP and a documented decrease in visual acuity (VA) to 20/60 or worse caused by macular edema refractory to medical therapy.
  
  
  METHODS
  Pars plana vitrectomy was performed in the 12 eyes, followed by posterior hyaloid dissection, removal of the posterior inner limiting membrane after staining with indocyanine green, and gas tamponade. Preoperative best-corrected VAs ranged from 20/60 to 20/400 (mean, 20/115).
  
  
  METHODS
  Changes in VA and foveal thickness as determined by optical coherence tomography (OCT).
  
  
  RESULTS
  The mean preoperative retinal thickness at the fovea was 477 micro m. Optical coherence tomography showed a decrease in macular thickness of >40% in 10 eyes (83.3%), with a mean postoperative foveal thickness of 260 micro m. The mean VA increased from 20/115 to 20/45, with an average of three lines of improvement.
  
  
  CONCLUSIONS
  Our results suggest that vitreoretinal surgery may effectively manage macular edema in RP.
