title: [Surgical removal of choroidal neovascularization in angioid streaks].
abstract: OBJECTIVE
  All the studies so far on surgical removal of choroidal neovascularization (CNV) in angioid streaks(AS) were conducted on a small number of cases. Therefore, a definitive evaluation of the surgical method was not available. The present study aimed to evaluate this surgical modality.
  
  
  METHODS
  We performed surgical removal of foveal CNV accompanied by AS. Eighteen eyes of seventeen patients were available for follow-up of over 12 months. Surgical indications included foveal CNV, fluorescence leakage from the CNV in late-phase fluorescein angiography, and visual acuity of 0.3 or lower.
  
  
  RESULTS
  The best visual acuity was improved in 44% and unchanged in 44%. The final visual acuity was improved in 33% and unchanged in 39%. 22% had a preoperative visual acuity of 0.2 or above; and 44% and 17% achieved best and final visual acuity, respectively, of 0.2 or above. Since all cases developed atrophy of the choriocapillaris in the fovea, none of the cases were capable of fixation within atrophy. The fixation point was localized outside atrophy in 56% and fixation was poor in 44%. The diameter of postoperative atrophy of choriocapillaris was significantly greater (p < 0.05) than the preoperative CNV diameter. CNV recurred in 8 eyes(44%), 88% of which occurred within one year.
  
  
  CONCLUSIONS
  Surgical removal of CNV in AS is an effective method to maintain preoperative visual acuity.
