| Summary: |
Transpupillary
thermotherapy (TTT) is a method for treating small
melanomas. An infrared diode laser (810 nm) and a
modified slit-lamp delivery system deliver energy
through the pupil to the choroid. This causes elevation
in local tissue temperatures to 45-60°C resulting in
tissue necrosis. TTT is capable of causing necrosis of
tumors up to 3.9 mm in thickness. To reduce the risk of
recurrence “sandwich” treatment can be used where TTT
treats the tumor apex and brachytherapy treats the tumor
base. This combination therapy enables TTT to be used in
tumors greater that 4 mm in thickness and may decrease
the risk of radiation related complications.
The most common complications associated with TTT
include: iris lesions, irydocyclitis, posterior
synechiae, cataract, haemorrhages within the tumor mass,
subretinal and intravitreal haemorrhages, overlying
branch vascular occlusion, macular edema and preretinal
fibrosis, optic disc edema and retinal detachment. |
