title: Anatomical success rate after primary three-port lens-sparing vitrectomy in stage 5 retinopathy of prematurity.
abstract: OBJECTIVE
  To assess the anatomical success rate after three-port lens-sparing vitrectomy (LSV) in stage 5 (total) retinal detachments secondary to retinopathy of prematurity.
  
  
  METHODS
  In a retrospective, interventional, single-surgeon, consecutive case series, the records of 33 eyes of 21 patients presenting with stage 5 retinal detachment secondary to retinopathy of prematurity who underwent primary three-port LSV from February 1998 to January 2004 were evaluated. Twenty-one eyes (63.6%) had open anteriorly-open posteriorly and 12 (36.4%) had open anteriorly-narrow posteriorly in terms of anatomical configuration. The main outcome measure, retinal reattachment, was reviewed at final follow-up visits, which ranged from 6 months to 48 months (mean, 32 months) after LSV.
  
  
  RESULTS
  Fifteen eyes (45.5%) maintained attachment and 18 eyes (54.5%) remained detached at the final visit. Open anteriorly-open posteriorly configuration eyes had a statistically significant higher anatomical success rate than eyes with an open anteriorly-narrow posteriorly configuration (P<0.001).
  
  
  CONCLUSIONS
  Three-port LSV may achieve anatomical success in stage 5 retinopathy of prematurity-related detachments. The open anteriorly-open posteriorly configuration portends a better prognosis; thus, surgery should be performed before closure of the posterior retina into a funnel configuration, if possible.
