Abstract

The attempts to treat conservatively the intraocular tumors saving the eye and its functions are made with increasing frequency. For this purpose photocoagulation, beta-application exposure, protonotherapy, diathermocoagulation and cryodestruction of the tumor are performed (Terentjeva, 1969; Ziangirova et a!., 1969; Brovkina et al., 1977, 1982; Brovkina, Zarubei, 1986; Volkov et aL, 1987; Orellana, McPherson, 1984; Char, Phillips, 1985; Tse, 1986; Gurretson et aL, 1988; Manschot, van Sink et a!., 1988). According to Bezrukov (1988) enucleation still remains the main approach (84%) to the uveal melanoma treatment in Russia. However, this procedure performed even at the early stage of the tumor growth is not absolutely reliable to prevent the tumor metastasis. According to the different authors the postenucleation mortality rate Within first 5 years accounts for 24-45% depending on the stage of disease and within 10 years - 65-80% (Steinberg, 1967; Kotelyansky, 1974; Manschot, van Peperzeel, 1980; Bacin ci a!., 1988; Saraux, Pelosse, 1988 et al.). Thus a search for new radical methods of the uveal melanoma treatment proves to be urgent. The application of lasers in the clinical practice has opened the new era in the treatment of the intraocular neoplasms. According to Terentjeva (1975) the clinical efficiency of this method accounts for 89.5% in tumors with protrusion up to 4.5 diopters. Therefore the most promising trend in the therapy of the eye tumors is the development of new methods that can be used to treat large lesions. With this in case the application of new laser sources and special modes of irradiation may significantly extend indications for conservative treatment.
