retinal laser coagulation

Purpose: to evaluate the peripheral vitreoretinal interface changes after combined laser-surgical treatment of local rhegmatogenous retinal detachments revealed by wide-feld OCT. Material and Methods. 21 patients (21 eyes) with local rhegmatogenous retinal detachment localized in the upper half of the fundus were enrolled in this study. All patients underwent a combined laser-surgical treatment, which included 3 steps: 1) Nd: YAG laser excision of the vitreoretinal adhesion zone, determined by wide-feld OCT; 2) pneumatic retinopexy; 3) barrier laser photocoagulation at the edge of the tear after retinal reattachment. All patients underwent OCT of the peripheral vitreoretinal interface to identify areas of pathological vitreoretinal adhesions in the post-operative period. Results. OCT analysis of 21 patients has demonstrated the complete elimination of the traction component in the treatment area. However, vitreoretinal adhesions near the tear area were found in 4 patients. These patients underwent additional barrier laser photocoagulation at zones of pathological vitreoretinal traction. Conclusion. Visualization of

Aggressive posterior retinopathy of prematurity (AP-ROP) is the most severe form ofretinopathy of prematurity (RP), characterized by early onset, fulminant course with absence of stagingand resistance to treatment. Today, the increase in AP-ROPincidence is associated with the changing standards for nursingof severely premature infants and wideprevalence of assisted reproductive technology — in vitro fertilization (IVF). The article presents a clinical case of aggressiveposterior retinopathy of prematurity in a girl with agestational ageof 25 weeks and a birth weightof about 860 grams who was conceived by IVF. Medical and high-tech laser treatment, fullycarried out in time, has lead toregression of this disease, which mayallowto preserve and develop visual function.
