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.

The most common symptoms experienced by patients with VMT syndrome are: Decreased sharpness of vision; Photopsia, when a person sees flashes of light in the eye; Micropsia, when objects appear smaller than their actual size; Metamorphopsia, when vision is distorted to make a grid of straight lines appear wavy or blank

2013年4月26日 · Vitreomacular adhesion, VMT, and FTMH were defined by anatomic criteria that must be present on at least 1 OCT B-scan image and classified by size of attachment or lesion and presence of concomitant retinal or vitreoretinal conditions.

Stage 0 (Other eye should have full thickness macular hole) Vitreomacular traction (VMT) The following must be present on at least one OCT B-scan image: (i) Partial vitreous detachment as indicated by elevation of cortical vitreous above the retinal surface in the perifoveal area

2023年3月17日 · Use this cheat sheet as a step-by-step guide to accurately identify and classify macular holes. Since vitreomacular interface disease is caused by age-related changes to the vitreous and VMI, it makes sense that these conditions are seen more commonly with aging.

VMT syndrome is most common in older adults and women due to age-related vitreous changes and vitreous liquefaction associated with declining post-menopausal estrogen levels, respectively. • Other risk factors include: • High myopia (extreme nearsightedness) • Exudative (wet) age-related macular degeneration • Diabetic macular edema

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...

Stages of the development of MH from focal VMT to complete aperture together with accompanying symptoms have been described by Gass [18, 19]. The introduction of enzymatic vitreolysis [ 20 ], which can result in the liberation of VMT, opens highly interesting new perspectives in this field.

Initially, it usually occurs with vitreo-macular attachment (VMA) before separation but can be complicated by vitreo-macular traction (VMT) which can cause a macular hole. This Clinical Management Guideline outlines the aetiology, signs and symptoms and evidence-based management options for diagnosing PVD, VMA, VMT and macular hole.

2024年3月21日 · Stage 2: A full-thickness retinal defect <400μm in diameter with vitreomacular traction (VMT). Stage 3: A full-thickness retinal defect ≥400μm in diameter with VMT. Figure 1 demonstrates a dissecting microscope image of a macular hole. Figure 1: …
