PURPOSE: To evaluate the usefulness of indocyanine green (ICG) in the photodynamic therapy (iPDT) of choroidal melanoma.
MATERIAL AND METHODS: Thirty eight patients with choroidal melanoma were treated with iPDT. Tumor thickness ranged from 2.6 to 4.1 mm in ultrasonography. Before iPDT Ruthenium-106 plaques were used in 18 cases, in 6 cases with additional transpupillary thermotherapy ("sandwich method"), and Iodine-125 plaques in 3 cases. In 11 eyes the iPDT was the only performed treatment. Therapy was performed with 810 nm diode laser after intravenous injection of 25 mg solution of indocyanine green. Six months after iPDT ophthalmological examination was performed with ultrasonography and ICGA images evaluation.
RESULTS: The baseline ICG study showed pathological intrinsic vasculature in all examined cases. Six months after iPDT changes in microcirculation, as well as significant decrease of tumors thickness in ultrasonography (mean 38%), were detected in all cases. Complete regression of intrinsic vessels was demonstrated by ICGA in 26 cases, and partial regression of pathological vascularization was found in 12 patients.
CONCLUSIONS: Our preliminary study suggests, that ICG mediated iPDT can be a new and promising way, to treat choroidal melanoma.
