Abstract

Analysis of experimental data is the evidence, that coagulation thresholds of the eye fundus with lasers irradiation, transmitted transsclerally by a monofiber with its tip compression into the sclera appeared to be lower than the thresholds of coagulation in transpuppilar methods of applications in the identical parameters of laser irradiation. Essential distinctions of the character of interaction between laser radiation and choroid in transmission of irradiation by a monofiber with compression of its tip into the sclera allowed bus to substantiate and recommend for a clinical usage the contact-compressive transscleral method of laser microsurgery, which is characterized by the following: low thresholds of coagulation of intraocular structures; wide therapeutical range of energy; low risk factor of possible complication results; simplicity of the method realization; possibility to use irradiation in all spectra range of collagen transparency.
