[Comparative evaluation of the efficiency of transscleral diode laser cyclophotocoagulation during contact and contactless procedures: experimental morphological study].

To elucidate the extent to which contact and contactless procedures of diode laser transscleral cyclophotocoagulation (CPC) has a antihypertensive effect and a ocular tissue damaging effect, the authors have made a comparative assessment of the procedures to determine their preference. The study was conducted on an experimental material (5 Chinchilla rabbits (10 eyes)). The follow-up was 1 day to 6 months after laser interventions. The authors estimated the parameters of ocular hydrodynamics before and laser intervtntion throughout the follow-up and analyzed them with morphological changes kept in mind. The final antihypertensive effect of both contact and contactless procedures was virtually equal. However, less inflammatory changes and lower ocular damaging effect, and no additional medical manipulations for contactless diode laser CPC make it more preferable to contact CPC for clinical use.
