title: The effects of laser photocoagulation on reopened macular holes, as assessed by optical coherence tomography.
abstract: OBJECTIVE
  To evaluate the effects of laser photocoagulation on reopened macular holes.
  
  
  METHODS
  This study involved 9 eyes from 9 patients who underwent laser photocoagulation coupled with fluid-gas exchange for reopened macular holes. The photocoagulation was performed at the center of the macular hole. Closure of the reopened hole was categorized by optical coherence tomography (OCT) according to the presence (type 1 closure) or absence (type 2 closure) of continuity in the foveal tissue. Best corrected visual acuity (BCVA), closure types, and complications were assessed.
  
  
  RESULTS
  Upon final examination, all macular holes were found to have closed. Six eyes were classified as type 1 closure, and three were classified as type 2 closure. The mean BCVAs, before and after laser photocoagulation, were 0.11 and 0.31, respectively (P<.05). The eyes with type 1 closure were associated with shorter symptom durations and greater visual improvement than those with type 2 closure (P<.05).
  
  
  CONCLUSIONS
  The combination of laser photocoagulation and fluid-gas exchange appears to be a safe and effective treatment for reopened macular holes. Early intervention should be encouraged to ensure complete hole closure and improved visual outcomes.
