Abstract
SummaryMembranectomy is critical and one difficult stages of macular surgery. The difficulty is caused by heterogeneity of the adhesion of epiretinal tissue to the retina, and if it is large, traumas of the retina appear that are the main cause of loss of visual fields in the central area. Also, that in the overwhelming majority of cases (more than 50%), the onset of membranectomy is accompanied by a trauma of the retina, which occurs when the epiretinal tissue is first captured with forceps. Selective surgery, in which the map of adhesion of epiretinal tissue to the retina is created with the help of OCT at the preoperative stage and membranectomy is carried out only in areas of low adhesion, significantly reduces the probability of traumas of the retina.In the process of vitrectomy and membranectomy, the redistribution of mechanical stress occurs in the epiretinal tissue. Because of this, the topology of the adhesion map changes. Dislocations of the boundaries of high adhesion zones in the process of membranectomy can reach 1.5 mm and with the probability greater than 0.7 are greater than 0.5 mm.Uses endoOCT allows to control these changes in process of surgery, allowing it is essential to increase its efficiency.
