Purpose: To evaluate retinal damages shortly after transpupillary thermotherapy (TTT) for age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV). Methods: Fourteen consecutive eyes of 14 patients with occult or classic choroidal neovascularization secondary to AMD and 11 consecutive eyes of 11 patients with PCV underwent TTT. TTT was delivered through a slit lamp with an 810 nm diode laser, for a 3.0 mm beam the settings were between 300 - 400mW, for a 2.0 mm between 200 - 270mW. Fluorescein angiography (FA) was performed before the treatment, and one day and one month after the treatment. Results: FA at one day after TTT showed leakage from retinal capillary or occlusion of retinal capillary in the treated area in 6 eyes (43%) of the 14 eyes with AMD and 6 eyes (55%) of the 11 eyes with PCV. These angiographic changes completely disappeared at one month after the treatment. Conclusion: Although TTT is administered as a subthreshold photocoagulation with no visible endpoint and no ophthalmoscopically apparent chorioretinal change during the treatment, the damage to the overlying retina may occur temporarily after the treatment.
