Morphological changes in chorioretinal complex of rabbit immediately after exposure of high frequency electric current (modified generator ec-300m1) compared with diode lazer coagulation

Abstract

В результате экспериментального исследования, выполненного на 7 кроликах (14 глаз), установлено, что наиболее выраженным деструктивным действием на сетчатку и сосудистую оболочку обладает пороговая диодная эндолазерная коагуляция. Меньшее деструктивное действие отмечено при высокочастотной электросварке биологических тканей с напряжением 18–20 В. Наиболее щадящее действие оказывает высокочастотная электросварка с напряжением 14–16 В.Harmful effects minimizing of some factors, including laser, electric current on the eye tissues during various interventions is relevant area of ophthalmology. High frequency electric welding of biological tissues (HEWBT) can be considered as an alternative method of retinopexy with an ability to minimize the destructive effects of electric current on the retina and choroid. Purpose. To investigate the chorioretinal complex morphological changes in rabbit immediately after high-frequency electric current exposure (modified generator EC-300M1). Materials and methods. 7 rabbits (14 eyes) were in experimental studies. Group I: animals applied for welding applications on the retina using technology HEWBT with parameters: voltage — 14–16 V, current — 0.1 A, exposure 1–2 s, frequency 66 kHz). Group II: welding applications with a voltage of 18–20 V. Group III — chorioretinal burn formed using threshold diode endolazer coagulation. In the control group, no intervention was performed. Animal’s eyes were subjected by histological examination
