Conclusions<br />

Photothermal <strong>therapy</strong> is attractive because:<br />

- wide range of applications<br />

- no prolonged cutaneous photosensitivity<br />

- possibility to treat pigmented tumours<br />

- does not depend on reactive oxygen species<br />

Disadvantages:<br />

- tissue burning due to “over-treatment” (retinal burns)<br />

- hemorrhage (especially in retina)<br />

- light penetration in large tumours<br />

- fluorescence cannot be used for diagnosis
