PURPOSE: To study the relationship between the size of primary full-thickness macular hole (MH) and the vitreomacular attachment status. DESIGN: Single-centre retrospective observational case series. METHODS: The records of 100 consecutive eyes operated for primary full-thickness MH were retrospectively reviewed. The vitreous status and MH diameter were assessed on the preoperative optical coherence tomography scans. MH were classified depending on the presence or absence of vitreomacular traction (VMT) and their size as small (<250 µm), medium (250-400 µm) and large (>400 µm), as suggested in the International VMT Study Group Classification...

Vitreomacular adhesion (VMA) describes the adhesion of the posterior hyaloid face to the inner retina in any part of the macula. This can arise after incomplete separation of the posterior vitreous cortex from the macula during vitreous liquefaction. While the VMA may resolve spontaneously, a strong and persistent adhesion can lead to a variety of anatomical changes, including vitreomacular traction (VMT) and macular hole (MH). Both conditions can present with metamorphopsia and decreased vision. In cases of symptomatic VMT and full-thickness macular hole, pars plana vitrectomy has long been the standard of care...

PURPOSE: Retinal vein occlusions (RVO) are a major cause of vision loss in people aged 50 years and older. Current therapeutic options limit the consequences of RVO but do not eliminate the cause. Cannulation of the involved vessel and removal of the clot may provide a more permanent solution with a less demanding follow-up. However, cannulation of smaller retinal veins remains challenging. This paper explores the use of ocriplasmin (recombinant plasmin without its kringles) to clear RVO, using a robotic micromanipulator...

BACKGROUND: If left untreated, vitreomacular traction (VMT) will infrequently improve through spontaneous resolution of vitreomacular adhesion (VMA), and patients remain at risk of further deterioration in vision. The mainstay of treatment for VMT is vitrectomy, an invasive procedure that carries the risk of rare but serious complications and further vision loss. As such, a 'watch and wait' approach is often adopted before this surgical intervention is performed. Ocriplasmin (microplasmin) is a potential alternative treatment for patients with symptomatic VMT that may remove the requirement for vitrectomy...

INTRODUCTION: Pharmacologic vitreolysis is a strategy used to treat anomalous posterior vitreous detachment, by weakening vitreoretinal adhesion with an intravitreal drug. Pharmacologic vitreolysis facilitates surgery, and abnormalities of the vitreoretinal interface including vitreomacular traction (VMT) and early stage macular hole (MH) could be resolved. Ocriplasmin is a recombinant protease, active against fibronectin and laminin, which are important components of the vitreoretinal interface...

PURPOSE: To assess outer retinal architectural alterations after intravitreal ocriplasmin with a novel automated ellipsoid zone (EZ) mapping algorithm. METHODS: A single-center, retrospective, consecutive case series of image analysis was performed. Quantitative assessment of EZ status imaged with spectral-domain optical coherence tomography was performed before and after single intravitreal injection of 0.125 mg of ocriplasmin (Jetrea, Thrombogenics). A novel EZ mapping algorithm was used to assess the EZ retinal pigment epithelium (RPE) central area, EZ-RPE macular volume, and en face EZ integrity based on the percentage of sampling areas with 20 μm or greater EZ-RPE thickness...

Treatment is usually indicated for symptomatic vitreomacular traction (VMT) with or without a full thickness macular hole (FTMH) and without spontaneous resolution. Ultrastructural parameters are evaluated by SD-OCT, in order to classify the vitreoretinal interface and to estimate the success rate of treatment. The resolution rate after therapy with intravitreal Jetrea® (Ocriplasmin) is high (up to 70 %) in patients with symptomatic focal vitreomacular traction (≤ 1500 µm) with or without a macular hole (≤ 250 µm) and with no epiretinal membrane (ERM), but depends on the exact baseline analysis...
