✦ Synopsis

Investigation of laser treatment of intraocular tumors
is of great interest for laser applications in ophthalmology and
oncology. The main problem of laser treatment of tumors is to
achieve complete coagulation of tumor body (volume) while the
functioning of neighboring layers is preserved. The possible
routes of laser irradiation (transpupillar, transscleral,
endoscopic) of intraocular tumors are discussed. The investigation
and selection of most appropriate wavelengths of laser radiation
was made on the base of analysis of optical characteristics of
pigmented and nonpigmented tumor tissues taking into account
optical parameters of tumors, blood, melanin, water and results of
computer modelling. It was established that radiation spectral
interval between 1 and 1.3 ΞΌm (diode lasers with wavelengths
between 1.0 - 1.3 ΞΌm and Nd – Yag laser 1.064, 1.318 ΞΌm) is appropriate for these goals.
