What does vitreomacular traction mean?
What does vitreomacular traction mean?
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 …
What is a Schisis?
Schisis is derived from the Greek word meaning splitting, describing the splitting of the retinal layers from each other. However, schisis is a word fragment, and the term retinoschisis should be used, as should the term iridoschisis when describing splitting of the iris.
What is white without pressure?
White without pressure (WWP) describes a finding that your retina doctor may see when examining the peripheral retina. WWP is found in 15-30 percent of the population and is characterized by a discrete whitish-gray area in the far peripheral retina that is bordered by a dark line.
How common is VMT?
How common is Vitreomacular Traction Syndrome? VMT only occurs in about 1 in 4400 people. The occurrence of VMT in patients with diabetic retinopathy, age-related macular degeneration, and other macular diseases is much higher. It occurs in women slightly more often than men and can happen at any age, in any race.
What is Snowflake eye?
Snowflake vitreoretinal degeneration is an autosomal dominant condition characterized by fibrillar anomaly of the vitreous, peripheral retinal abnormalities including minute crystalline deposits resembling snowflakes, and early-onset cataracts.
What is visualvitreomacular traction syndrome?
Vitreomacular Traction Syndrome. The vitreous humor is a transparent, gel-like material that fills the space within the eye between the lens and the retina. The vitreous is encapsulated in a thin shell called the vitreous cortex, and the cortex in young, healthy eyes is usually sealed to the retina.
What are the treatment options for vitreomacular traction (VMT)?
After a diagnosis of vitreomacular traction (VMT), there are usually three treatment options: Observation or a “wait-and-see” approach. If your VMT is mild and not affecting your vision, treatment might not be needed.
What happens if you get a macular hole from vitreomacular traction?
Vitreomacular traction can lead to a macular hole. A macular hole will distort and blur the central vision and, in most cases, needs surgical intervention in order to reduce the likelihood of permanent vision loss.
Why does the vitreofoveal attachment cause anterior traction?
This leads to a static anterior traction due to the elastic properties of the vitreous and results in foveal elevation or distortion. Additionally, ocular rotations occurring with eye movements may exert dynamic anterior traction at the site of the vitreofoveal attachment.
