Abstract

In experiments were worked out an din clinical practice were approved two original techniques of photocoagulation- photoablation destruction of rather volumetric intraocular tumors by thickness greater than 3 mm with the help of deeply penetrating IR laser radiations of A-range. In variant of transpupillary effect preference returned to quasicontinuous radiations ophthalmonocoagulator 'Landoga- Neodymium'. At pulse duration measurable in hundreds of microseconds with frequency of following up to 50 Hz and energy in impulse about 100 millijoules it was possible to destroy tumors in 85 cases among 122. Total absorbed energy in the target was varied from 500 until 1500 Joules. Periods of observation last 4-12 years. Diode laser of the 'Milon' corporation with a glass-fiber tip was applied in a course of vitreoectomy in variant of contact compressive effects on juxtapapillary located tumors. Applies constant radiation power 1.6 W. Tumors were liquidated at total absorbed energy also up to 500 pulses in 11 cases among 12. Periods of observation laser 2-4 years. Both variants of laser treatment deserve more broad application in clinical practice.
