377Computational Modeling of Thermal Damage Induced by Laser in a Choroidal Melanoma
3. The laser radiation penetrated into the tissue without scattering.
4. The different tissues were homogeneous and isotropic.
5. The blood temperature was assumed constant and equal to 37°C [39].
6. The generation of metabolic heat was not considered, since it is often less than the
amount of heat deposited by laser radiation (Q
m
<< Q).
7. The melanoma and retina were considered as one region (tumor) because the
retina has a very small thickness and because the largest portion of the infrared
radiation is absorbed in the tumoral tissue, which is rich in melanin.
8. The thermophysical properties of the iris and the ciliary body were considered
identical ...
