title: Photodynamic therapy with verteporfin for peripapillary choroidal neovascularization.
abstract: OBJECTIVE
  To evaluate the efficacy of photodynamic therapy with verteporfin in the management of symptomatic extrafoveal peripapillary choroidal neovascularization (CNV).
  
  
  METHODS
  Seven eyes of seven patients with symptomatic peripapillary CNV underwent visual acuity testing, ophthalmic examination, color photography, and fluorescein angiography to evaluate the results of photodynamic therapy with verteporfin. Patients were offered treatment following the development of hemorrhage, subretinal fluid, or lipid if it was associated with visual symptoms. A standard nomogram was used to dose Visudyne, application was performed in three separate 30-second zones confluent over the extent of the lesion. The light dose per unit area applied to the retina was approximately 18 J/cm.
  
  
  RESULTS
  Five of the seven had CNV limited to the peripapillary area associated with age-related macular degeneration; the remaining two eyes had presumed ocular histoplasmosis syndrome. In five of the seven eyes, two treatments were needed and in two eyes only one treatment was necessary to elicit resolution of active leakage. Retreatment was performed at an average of 76 days after initial treatment. Baseline best-corrected visual acuity (BCVA) ranged from 20/20 to 20/150. Final BCVA ranged from 20/20 to 20/80. In all eyes except for one, which had a pretreatment vision of 20/20, at least two lines of Snellen visual acuity improvement were achieved. Resolution of submacular fluid, hemorrhage, or exudates was noted in six eyes; in the remaining eye there was persistence of subretinal lipid. There were no complications including optic neuropathy in any of the treated eyes. Follow-up ranged from 6 to 13.5 months following last treatment (mean, 10 months).
  
  
  CONCLUSIONS
  Photodynamic therapy with verteporfin for extrafoveal symptomatic peripapillary CNV appears to be effective in improving vision and promoting the resolution of subfoveal exudates, hemorrhage, or fluid. A randomized controlled study with longer follow-up is justified.
