Оценка клинической эффективности хирургического лечения идиопатических макулярных разрывов большого и среднего диаметра с использованием модифицированной технологии инвертированного лоскута внутренней пограничной мембраны (предварительные результаты)

Abstract

Purpose. To assess the clinical effectiveness of surgical treatment of medium-and large-diameter idiopathic macular ruptures (IMR) using a modified technology by inversion and fixation of a free flap of the internal limiting membrane (ILM). Methods. A prospective study was conducted in 11 patients (11 eyes), 9 women and 2 men with medium-and large-diameter IMR. Mean age - 67.3 ± 5.38 (55-80) years. Patients with penetrating IMR of 2-4 stages according to the J. Gass classification. All patients underwent optical coherence tomography (OCT) along with traditional ophthalmological methods. The scans were performed in Retina Map, Cross line, Radial line, and Angio Retina modes. The obtained images were used to measure the parameters of the macular rupture (MR) of the retina manually. All patients underwent surgical treatment of IMR according to the proposed method. Results. In all cases, 1 day after the surgery, the closure of the gap was achieved according to ophthalmoscopy. 1 month after the surgery, according to OCT, 3 patients (27.2%) had a defect in the photoreceptor layer, 4 patients (36.3%) had deformity or peripheral non-attachment of the edges of the ILM flap, and 2 patients (18.1%) had a combination of these defects. According to OCT data in the Angio Retina mode, changes in the parameters of retinal blood flow were noted: there was a significant, moderate expansion of the avascular zone, accompanied by a moderate decrease in retinal perfusion. Despite this, there was a significant increase in visual acuity in the postoperative period. Conclusion. Endovitreal intervention for medium-and large-diameter macular ruptures using a modified technology by inversion and fixation of an ILM free flap is highly effective, as well as a low-traumatic treatment method that allows achieving anatomical closure of the macular defect and improving visual functions.
