Comparative analysis of the oct and microperimetry data to assess the state of the central regions of the retina following the relapse of a macular rupture

Abstract

Background. In 810% of cases after the surgical treatment, macular ruptures do not close. Aim: to assess the morphological and functional parameters of the macular area following the surgical closing of previously operated macular ruptures using a free flap of the internal limiting membrane and silicone oil tamponade. Methods. This study involved 31 patients, all the patients underwent a surgical treatment applying a free ILM flap and silicone tamponade, the standard diagnostic procedures and optical coherence tomography and microperimetry were also used (before the operation, on the 14th and on the 30th day after the operation). Results. The change in the morphological parameters of the retina directly correlates with the change of the functional parameters of the macular zone, and a peak of the increase in the retina photosensitivity occurs in the early postoperative period with a slight further increase in the long-term postoperative period. Conclusions. The surgical treatment of unclosed macular holes, namely the creation of a free flap of the internal limiting membrane, or a plug, as well as the use of silicone tamponade, ensures a reliable positiveanatomical and functional postoperative result.
