Ultrasonically produced hyperthermia in ophthalmology

The effects of ultrasonically induced hyperthermia on experimental tumors in the rabbit eye.

Greene's melanomas, implanted in the anterior chamber of 31 eyes of 19 Dutch rabbits, were treated with hyperthermia induced by high intensity focused ultrasound (HIFU). The percentage necrosis 24 hr after treatment (N) as a function of steady-state intratumor temperature (T) could be described with N(T) = -181.5 + 4.7T (P less than 0.05). The most frequent side effect was a local hemorrhagic k...
