Retina damage and repair after high-frequency monopolar electrocoagu-lation by suprachorioid access

Retinal detachment (RD), its rupture, concussion, hemorrhage require urgent ophthalmic surgical intervention without fail. Restoring the anatomical integrity of detached retina, speed intervention, choice access and method surgery, quality instrument are directly causally related to visual acuity, number severity postoperative complications. The best complex ophthalmosurgical solutions relieve vitreoretinal surgeons need for vitrectomy tamponade, provide sufficient strength chorioretinal connection, cause little oedema in site, a minimal atrophy, quick repair process. An important objective indicator optimal tool, nature is damage retina neurolayer decrease thickness due impact. This publication devoted second phase an experiment on animals, which simulates operation restore retina. parameters high-frequency monopolar electrocoagulation (current 0.1 A, voltage 10–16 V, frequency 66 kHz, suprachoroidal access, original design with extreme part sphere diameter 25 G) remain unchanged. For experiment, 30 adult rabbits (60 eyes) were used, divided into three experimental groups (10 20 eyes each) according exposure (I – 10–12 II 12–14 III 14–16 V) euthanized 1 week, 2 weeks month after surgery. took account data first regarding control (IV) group included 6 intact (12 eyes), as well observations hour 3 days operation. morphological structure rabbit was studied emphasis processes oedema, atrophy Keywords: retinal detachment, thickness.
