Dynamics of changes of microperimetry parameters of retina by closure of macular hole with preservation of internal limiting membrane

Objective: To evaluate the medical effectiveness of the macular hole closure (MH) technique, which is based on the limiting of the internal limiting membrane (ILM) peeling. Material and Methods: The results of surgical treatment of 80 patients (80 eyes) diagnosed with MH were analyzed. Patients are divided into two groups: group 1-patients who had a standard peeling; group 2-patients who were operated on using the original method with partial peeling of the macular area. All patients underwent visometry, biomicroscopy, ophthalmoscopy, and OCT-examination. Results: By the 30th day after surgical treatment, a statistically significant excess of light sensitivity parameters was detected in the nasal part of the pattern used: the upper-nasal and lower-nasal quadrants, where peeling was not performed (p=0.032) and (p=0.034), respectively. In the 1st observation group, the recovery of the fixation point was observed during the early and late operating period and at 12 months was 58.3% (p=0.041). In group 2 patients, by the time of 1 month after surgery, the recovery of the fixation point occurred in 88.7%. Conclusion: When conducting the method of limited peeling, the ILM is preserved, which reduces the risk of intraoperative damage to the retina layers. A higher functional result was obtained in comparison with the group where the standard method was used.
