Two-port vitrectomy in the treatment of patients with macular hole

Purpose. Analysis of the first clinical and functional results of treatment of patients with macular holes using the two-port vitrectomy. Material and methods. An analysis of treatment of 15 patients with a diagnosis of macular hole, operated by the method of two-port vitrectomy, was carried out. According to the Gass classification, 7 patients were diagnosed with stage 3 macular hole, and 8 patients with stage 4. All patients underwent microinvasive vitrectomy according to the developed technique. At the beginning of the operation, two ports were installed – one for the infusion cannula with a built-in illuminator (chandelier), the second for the vitreotome. Next, the epiretinal membrane (ERM) (if any) and the internal limiting membrane (ILM) were removed, and plateletrich plasma (PRP) was used at the end of the operation. Intra- and postoperative complications were not registered. Results. The maximum period of observation of patients after treatment was 3 months. In all cases, an anatomical result was achieved – complete closure of the macular hole according to optical coherence tomography (OCT). Mean BCVA results 3 months after treatment were 0.32±0.08. In all cases, improvement in visual functions was achieved (p=0.035). Conclusion. The method of two-port vitrectomy in the treatment of macular holes allows to achieve a good anatomical result, improve visual functions, while minimizing surgical trauma. Key words: macular hole, platelet-rich plasma, two-port vitrectomy.
