title: [Photodynamic therapy of circumscribed choroidal hemangiomas].
abstract: OBJECTIVE
  To evaluate the safety and efficacy of photodynamic therapy in the management of symptomatic circumscribed choroidal hemangiomas (CCH) with exudative activity.
  
  
  METHODS
  This prospective nonrandomized study included eight patients referred to us for management of CCH with exudative activity. PDT was applied by diode laser (689 nm) with a light dose of 100 J/cm2 and using verteporfin (6 mg/m2) IV bolus injection. The treatment spot diameter accurately corresponded to the tumor basal diameter (TBD).
  
  
  RESULTS
  The mean tumor thickness before PDT was 3.3 mm (range, 2.7-7.5 mm) and the mean largest TBD was 6.1 mm (range, 5-12 mm). All patients were managed with a single PDT application. After a mean follow-up of 24.2 months (range, 17-29 months), all CCH (100%) showed regression of tumor thickness and complete resorption of the serous retinal fluid; 87.5% of the patients showed a flat tumor scar. All CCH showed overlying PDT-related retinal pigmented epithelium atrophic changes. No case of retinal vascular occlusion or recurrent leakage was documented. Five patients (62.5%) showed visual improvement, one (12.5%) retained stable vision and two (25%) developed worse vision due to chronic exudation-related RPE changes in one patient and preretinal fibrosis in another.
  
  
  CONCLUSIONS
  PDT using verteporfin offers a safe and effective therapeutic option to manage CCH. Complete resorption of subretinal fluid is usually associated with visual improvement.
