[Transpupillary thermotherapy for treatment of choroidal melanomas].
OBJECTIVE
To report the results of transpupillary thermotherapy (TTT) for selected posterior pole choroïdal melanomas.


METHODS
Prospective study including 56 patients (mean age of 61 years) with choroidal melanoma treated with TTT. All treated tumors had either documented growth or clinical risk factors for future growth and for metastasis. The injection of infracyanine green (I CG) was randomized.


RESULTS
The mean initial tumor basal diameter was 7.8 mm and tumor thickness was 3 mm. Twenty-seven tumors (48%) touched the optic disc and sixteen (29%) were under the fovea. Among these 56 patients with choroidal melanoma, 47 patients (84%) presented with primary choroidal melanoma. 9 tumors (16%) were late recurrences after conservative treatment. A mean of three treatment sessions was delivered. After a mean follow-up of 30 months, tumor regrowth was documented in 4 patients (7%) and the visual acuity was the same than the pretreatment acuity in 26 eyes (47%). The mean final thickness was 1.8 mm (percent reduction of tumor thickness was 39%). Intraocular complications included retinal fibrosis and/of retinal striae in 12 eyes (22%) and vascular occlusion in 14 eyes (25%). No statistical impact of ICG administration on the tumor regression was demonstrated.


CONCLUSIONS
This series confirms the efficacy of transpupillary thermotherapy in the management of selected posterior pole choroïdal melanomas.
