Vitreomacular traction (VMT) syndrome is a potentially visually significant disorder of the vitreoretinal interface characterized by an incomplete posterior vitreous detachment with the persistently adherent vitreous exerting tractional pull on the macula and resulting in morphologic alterations and consequent decline of visual function.

2025年1月20日 · Vitreomacular traction (VMT) is characterised by abnormal adhesion of the posterior cortical vitreous with the macula causing distortion of the foveal contour and...

Optical coherence tomography (OCT) is a highly sensitive test and is routinely used to diagnose and characterize ERM, VMT, and associated retinal changes. Vitrectomy surgery is often indicated in affected patients who have a decrease in visual acuity, metamorphopsia, double vision, or difficulty using their eyes together.

2014年7月4日 · V-shaped and focal VMT led to tractional CME and MH while J-shaped and broad VMT were related to ERM and diffuse retinal thickening. The size and strength of the residual VMT may define the specific associated maculopathy.

Broad VMT with ERM Traction from two directions: anterior-posterior from VMT and posterior hyaloid and tangential traction from the ERM. This patient is 20/20 asymptomatic. Chronic broad VMT -> more likely to develop ERM

• The macular changes in VMT are often similar to the changes of the retina that result from an ERM. • In VMT, raised edges of adherent vitreous may be seen in a peripapillary distribution around the optic nerve head and is referred to as vitreopapillary traction. • This condition can be confused with optic nerve disorders

VMT and ERM can cause macular edema with or without cystic changes and sometimes intraretinal hemorrhage and cotton wool spots (in cases of full-thickness retinal distortion) and should be differentiated from other pathologies causing these intraretinal abnormalities.

2013年10月10日 · In many VMT cases, an epiretinal membrane (ERM; 10–20 μ m in thickness) develops during the early perifoveal stages of PVD (Figure 5). 2, 23 Histologically, two types of ERM can be...

In cases of VMT, treatment with ocriplasmin is indicated when traction is ≤1500 μm and in the absence of concurrent macular diseases (ERM). In the case of MH, the hole diameter should be ≤400, traction has to be present, and ERM should be absent.

2024年6月23日 · This chapter discusses the surgical management of epiretinal membranes (ERM) and vitreomacular traction (VMT), two disorders affecting the vitreoretinal interface. It explores anomalous posterior vitreous detachment, the …
