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...

PURPOSE: To assess the posterior vitreous release rates following a single, office-based intravitreal injection of expansile gas in treating vitreomacular traction. METHODS: Thirty eyes of 29 consecutive patients with symptomatic vitreomacular traction received a single, office-based intravitreal injection of up to 0.3 mL of 100% perfluoropropane (C3F8). RESULTS: Overall, vitreomacular traction release occurred in 25 of 30 eyes by the final follow-up visit (83% final release rate); furthermore, 90% (9 of 10 eyes) with diabetes mellitus released, 83% (5 of 6 eyes) with concurrent epiretinal membrane released, and 83% (5 of 6 eyes) previously treated with ocriplasmin released...

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...

Based on the indications, one-third to one-half of patients can achieve full-thickness macular hole (FTMH) closure with or without the separation of vitreomacular adhesion (VMA) within 28 days of ocriplasmin treatment. The authors report the case of a 63-year-old man with early VMA separation and delayed FTMH closure after ocriplasmin treatment. Four weeks posttreatment, the posterior vitreous detachment occurred at the optic disk, and the macular hole (MH) started decreasing thereafter. MH closure was finally achieved at 10 weeks posttreatment, leaving minimal subretinal fluid...
