Morphological changes in eyes after suprachoroidal high-frequency electrosurgical treatment of the retina

A variety of methods and approaches are used for the surgical treatment retinal detachment, among which high-frequency electrocoagulation through suprachoroidal access has attracted attention researchers. The research question concerned selection optimal mode with help a monopolar instrument original design, during strong chorioretinal adhesion occurs in short period time after intervention, there is no need tamponade, destruction cells structures minimized, associated temperature factor electrocoagulation. study was conducted on 52 rabbits (104 eyes), were divided into 4 groups: Group I – exposure voltage 10–12 V, frequency 66 kHz, current strength 0.1 (16 animals, 32 eyes); II 12–14 other parameters identical III 14–16 IV– intact rabbits, 8 eyes (control). animals euthanized, enucleated. Fragments areas fixed device measured an electronic jewelry scale by pulling thread tied to sample until ruptured. tissues complex also studied light microscopy staining histological sections hematoxylin-eosin. According indicators junction strength, V. Destruction at this did not differ from using voltages V but greatest 1 hour. week 2 weeks surgery. Keywords: electrocoagulation, surgery, adhesion.
