ABSTRACT
PURPOSE:
To evaluate the effect of subthreshold transpupillary thermotherapy (sTTT) in foveal subretinal fluid of small pigmented choroidal lesions.METHODS:
Retrospective, noncomparative, interventional case series. We reviewed patients with small pigmented choroidal lesions presenting foveal subretinal fluid and treated with sTTT to evaluate fluid regression.RESULTS:
We treated 13 patients with small pigmented choroidal lesions with a mean height of 2.02 ± 0.54 mm (range, 1.4-2.9 mm) and a mean largest diameter of 7.60 ± 1.98 mm (range, 5-11 mm). In 11 cases, foveal subretinal fluid was completely resolved (84.6%), with a mean follow-up of 42.46 ± 26.29 months (range, 12-103 months). The mean number of sTTT sessions applied was 1.38 ± 0.77 (range, 1-3 sessions), at a mean spot size of 1,570.59 ± 795.1 µm (range, 500-3,000 µm), and overall exposure time of 2.32 ± 1.2 minutes (range, 1-6 minutes). Mean laser power applied was 370.63 ± 162.87 mW (range, 200 to 600 mW). Best-corrected visual acuity at the time of diagnosis was maintained or improved in 69.3% of patients after sTTT treatment. During follow-up, tumor progression was reported in 5 cases, regardless of the presence of subretinal fluid. These cases were treated promptly with brachytherapy.CONCLUSION:
However, sTTT may be effective in solving foveal subretinal fluid in small pigmented choroidal lesions, attaining satisfactory visual acuity in most cases.
