Abstract
Purpose :
To evaluate the effectiveness of a single session of PDT for exudative circumscribed choroidal hemangiomas (CCH).
Methods :
Prospective non comparative case series including 33 patients with symptomatic exudative CCH. Our protocol included a single session of PDT performed 2 minutes after IV bolus injection of verteporfin (6mg/m2) at 689nm with a light dose of 100J/cm2 (600mW/cm2 for 166 seconds).
Results :
The mean tumor thickness before PDT was 3,5 mm (range, 2.6-6 mm) and the mean largest TBD was 6.6 mm (range, 4,5-12mm). After a mean follow-up of 104 months (range, 12-170 months), all CCH (100%) showed regressed tumor thickness, resolution of subretinal fluid and no recurrent leakage. Visual improvement was documented in 25 eyes (76%,P<0.001) and a flat tumor scar in 25 eyes ( 76%, P<0.001). No other PDT session was needed.
Conclusions :
This protocol with a single session of PDT offered a safe and effective option in treating symptomatic exudative CCH in terms of visual recovery, tumor thickness regression, and resolution of subretinal fluid with exudative recurrence.
