title: Surgical removal of submacular choroidal neovascularization: a clinicopathologic study and factors influencing visual outcomes.
abstract: OBJECTIVE
  Clinical and histopathologic characteristics of submacular choroidal neovascular membranes (CNV) are investigated and features predictive of postoperative complications or poorer visual outcome following CNV removal are identified.
  
  
  METHODS
  Records of patients who underwent submacular CNV removal at Bascom Palmer Eye Institute between 1991 and 1998 are reviewed.
  
  
  RESULTS
  At 6 months postoperatively, vision was stable or improved in 19/26 (73%) eyes, with 15/26 (58%) having 20/200 to 20/400 vision. Postoperative retinal detachment occurred more commonly in age-related macular degeneration eyes (AMD) (P <0.05), and CNV recurrence occurred most frequently in presumed ocular histoplasmosis (POHS) eyes (P <0.05). The one eye with an extrafoveal CNV in-growth site had the largest improvement in vision postoperatively. Choroid in the specimen was associated with worse postoperative vision (P = 0.05).
  
  
  CONCLUSIONS
  Submacular CNV removal achieves visual stabilization at the 20/200 to 20/400 level in most eyes. Potential risk factors for postoperative complications or poorer visual outcome include the underlying disease process, subfoveal in-growth site of CNV, and presence of choroid in the specimen.
