Изменение функциональных параметров центрального отдела сетчатки при использовании различных методик блокирования незакрывшегося макулярного разрыва

Abstract

Over the past decades, the surgical treatment of macular holes has been developing more and more rapidly, new methods of blocking an anatomical defect in the central part of the retina are emerging. However, the percentage of macular holes recurrence remains still high, according to various literary foreign and domestic sources, from 3 to 30 %. Purpose. Еvaluate the functional parameters of the retina using various methods of blocking an unclosed macular hole (creating a free ILM flap with the application of ACP-mass and tamponade with an air-gas mixture or creating a free ILM flap in combination with silicone oil tamponade). Material and methods. This study involved 92 patients, the patients were divided into groups according to the principle of repeated surgical intervention, the visual acuity, stability and displacement of the fixation point were studied in all patients. Results. In patients of both groups, an improvement in the functional parameters of the retina was noted, however, visual acuity and gaze fixation were better in the group with gas tamponade. Conclusion. Both proposed techniques for closing previously unblocked MRs are highly effective, however, the technique using a free ILM flap, application of ACP-mass and tamponade with an air-gas mixture provides better functional results due to the absence of toxic and mechanical effects of SO.
