title: Timing of acute macula-on rhegmatogenous retinal detachment repair.
abstract: OBJECTIVE
  To determine if same-day or next available surgery changed the outcome of patients presenting with acute macula-on rhegmatogenous retinal detachments.
  
  
  METHODS
  A retrospective review of patients presenting with acute macula-on rhegmatogenous retinal detachments treated with small-gauge vitrectomy was performed. Data collection included subjects' demographics, duration of symptoms, location and extent of the retinal detachment, and timing of surgery. The primary outcome was anatomical and functional success rate for patients having same-day surgery compared with those for whom surgery was delayed.
  
  
  RESULTS
  One hundred and fourteen patients were included in this study. Sixty-two patients operated on day of presentation, 46 patients operated the day after presentation, and in 6 patients, surgery was delayed from 2 to 5 days. Time to surgery in hours ranged between 1 and 120 hours (mean 14.5 ± 15.05 hours). Retinal reattachment was achieved in 95.6% of patients, with 80% requiring only one procedure. Mean initial visual acuity was logarithm of the minimum angle of resolution 0.42 (SD 0.6), and mean final visual acuity was logarithm of the minimum angle of resolution 0.39 (SD 0.67) (P = 0.53). Time to surgery was not found to effect final anatomical outcome (P = 0.56). No statistically significant association was observed between change in visual acuity and time to surgery (P = 0.99).
  
  
  CONCLUSIONS
  Modest delay in timing of surgery for macula-on rhegmatogenous retinal detachment did not adversely impact on patients' outcome.
