Experimental study of endoscleral and transscleral actions of IR radiationof diode, neodymium, and holmium lasers on the retina of the eye

This paper presents the results of experimental studies on the basis of the use of laser radiation with wavelengths of 0.83, 1.06, 1.32 and 2.09 mu m to carry out ophthalmological operations on the eye. It presents the result s of a comparative study in in vivo and in vitro experiments of the thresho ld laser-radiation energies that produce minimal changes of the retina at t he discrimination threshold, determined while the laser is being applied. T he action of continuous, pulsed, and pulsed-periodic laser radiations with pulse-repetition rates from 5 to 30 Hz on the retinas of rabbit and pig eye s is studied for both endoscleral and transscleral actions.
