    Journal: Arkh Anat Gistol Embriol; 1986 Mar; 90(3):33-4. PubMed ID: 3707373.
    Abstract:
    Morphological pattern of the retina in the trauma focus and outside its borders has been studied electron microscopically after application of ruby laser monoimpulse radiation (wave length 0.69 mcm, energy 1.06-1.25 X 10(-4) J and impulse length 20 nc). The trauma focus is not limited only by the volcano-shaped inflation of the retina. The lesion of the photoreceptory ultrastructure and the disturbance of microcirculation in the vascular layer are defined in 3 zones investigated: at the distance 50, 100 and 1,000 mcm from the spot on the retina, visible in the light microscope. This phenomenon should be taken into consideration when choosing therapeutic doses of laser radiation, applied for treatment of various diseases of the eye.
