With the developing optical coherence tomography technology it was possible to describe the vitreoretinal interface changes in detail. In this article, we aimed to evaluate the physiologic and pathological changes, vitreomacular adhesion (VMA), vitreoretinal traction (VMT), epiretinal membrane (ERM), full-thickness macular hole (FTMH), lamellar hole and pseudohole in the vitreoretinal interface.

Vitreous is an important ocular structure in the normal physiology and pathologic conditions of the posterior segment. Vitreous is a gel-like composite structure and forms an extracellular matrix that occupies the biggest space in the eye. The healthy vitreous gel reduces oxygen tension and protects vitreous, retina, and lens from oxidative damage. Vitreous plays an important role in the refraction of the eye, preserving the transparency with regular interaction of the macromolecules contained therein. Vitreous suffer from continuous physical tension and this results in important changes. Particularly age-related degeneration in the structure of the vitreous gel leads to a decrease in vitreoretinal adhesion. As part of natural aging, the posterior vitreous detachment process may become pathologic when the vitreoretinal interface weakens simultaneously with vitreous liquefaction. In this process, vision-threatening diseases such as vitreomacular adhesion, vitreomacular traction, and macula hole may appear.

Background. Diabetic macular edema (DME) is one of the main causes of decreased central vision. Determining the reasons for the refractoriness of DME to treatment is an urgent problem.Aims. Based on the analysis of optical coherence tomography, to study the features of pathological changes in the retina and vitreoretinal interface (VRI) in the macular zone in patients with DME.Materials and methods. We studied 587 patients (587 eyes) with diffuse DME in the setting of nonproliferative diabetic retinopathy. In addition to the standard ophthalmological examination, everyone underwent optical coherence tomography of the macular zone with an assessment of structural changes in the retina, morphometric parameters, and the state of the VRI.Results. In 351 patients (59.80 %) with DME, pathological variants of the VRI were revealed, in which the best corrected visual acuity was significantly lower, and the morphometric parameters (retinal thickness and macular volume) were signifi cantly higher. Analysis of morphostructural changes in the macular zone revealed that in pathological VRI, neuroepithelial detachment and high edema are more common, and cystic edema is larger in area compared to the group with a normal VRI. With detachment of neuroepithelium against the background of a pathological VRI, the worst morphometric data are determined, with solid exudates in the macula, the worst indices of visual loss are determined.Conclusions. The pathological VRI in patients with diabetic macular edema occurs in more than half of the cases and is characterized by a high incidence of neuroepithelial detachment, high edema, higher morphometric parameters with worse visual acuity. At the same time, the presence of neuroepithelial detachment corresponds to the worst morphometric indicators of the macular zone, and the presence of solid exudates corresponds to a lower maximum corrected visual acuity. Further research is needed to assess the effect of the listed morphostructural and morphometric changes in combination with various pathological variants of VRI on the effectiveness of DME treatment.

Purpose: To report a case of release of vitreomacular traction (VMT) in a patient with a full thickness macular hole (FTMH) immediately following pneumatic vitreolysis (PV) combined with head bobbing movements. Methods: A 71-year-old female with VMT and an FTMH presented with blurred vision for 2 months to the level of 20/400. At her 1-month follow-up visit, PV was performed using C3F8 gas and she was instructed to perform the drinking bird technique for ten minutes. Results: Optical coherence tomography performed ten minutes after PV with head bobbing showed VMT release and a smaller FTMH. Visual acuity improved to 20/150 immediately afterwards and to 20/80 two months later. Conclusions: Using the drinking bird technique for a continuous period of time immediately following PV may encourage rapid VMT release. PV may be a feasible option for patients with VMT and FTMH who do not want surgery.
