Horseshoe-shaped retinal tear leads to rhegmatogenous retinal detachment (RRD) in 61-83% of cases. Vitreoretinal traсtion is the main factor in the development of horseshoe tears and RRD. In this aspect, YAG-laser retinotomy is promising, which makes it possible to eliminate the traction component by excision area of the horseshoe tear with vitreoretinal adhesion (VRA). Purpose. To analyze the results of YAG-laser retinotomy in the treatment of patients with complicated horseshoe tears and rhegmatogenous retinal detachment. Material and methods. The study included 97 patients (100 eyes). Of these, 54 patients (57 eyes) with complicated horseshoe retinal tears and 43 patients (43 eyes) with local RRD. Patients with complicated horseshoe tears underwent YAG-laser retinotomy at the base of the horseshoe tear. Patients with local RRD underwent a combined laser-surgical technology, which included YAG-laser retinotomy of the horseshoe tear area with vitreoretinal adhesion, pneumatic retinopexy and barrier laser photocoagulation. Results. In the group of patients with complicated horseshoe tears, complete retinal attachment was achieved in 15 eyes (58%), partial retinal attachment - in 7 eyes (27%). In the group of patients with local RRD complete retinal attachment was achieved in 40 patients (93%). There was a stable anatomical result and no changes in functional parameters. Conclusion. YAG-laser retinotomy eliminates vitreoretinal traction in the area of horseshoe tear and prevents the development of rhegmatogenous retinal detachment. Application of YAG-laser retinotomy as the first step of a microinvasive combined laser-surgical technology for the treatment of RRD makes it possible to obtain a high anatomical result, reduce the risk of retinal redetachment, and also preserve the initially high visual functions of patients.
