Vitreomacular traction VMT syndrome is an eye condition involving the vitreous, the clear gel that fills the within the eyeball. It is a vision-threatening condition and can cause symptoms varying from lowered and blurred vision to distorted and blacked-out main vision. A lot of patients who have VMT syndrome experience some difficulty doing day-to-day tasks that require sharp vision, such as or playing computer game.
Vitreomacular traction can cause a macular hole. A macular hole will misshape and blur the vision and, in most cases, need to be resolved surgically in order to minimize the likelihood of long-term vision loss. To comprehend the mechanical reasons for VMT, we must first familiarize ourselves with posterior vitreous detachment is and how it connects to VMT. The vitreous is a clear, gel-like substance think of a jellyfish that fills about 80 percent of the inside of the eyeball.
The vitreous helps the eye maintain its round shape. As the vitreous shrinks usually due to aging it ends up being more liquefied, forming pockets of fluid within the vitreous which results in a contraction syneresis of the vitreous.
Typically, not long after this procedure starts, the vitreous separates from the retina entirely— this is called Posterior Vitreous Detachment— a typical condition that typically impacts individuals over age Once the vitreous has actually separated, the condition is virtually totally safe.
Vitreomacular traction occurs in cases where, rather of totally detaching, the vitreous adheres vitreomacular adhesion to the main vision part of the retina— the macula. As only part of the vitreous efforts to pull away, a tugging or pulling happens in the area of adhesion, causing actual physical modifications and distortion of the macula itself.
This relentless pulling on the macula typically causes swelling in its layers, a condition called Cystoid Macular Edema CME. CME can cause blurring and often distortion of the vision.
What Causes Vitreomacular Traction?
VMT just takes place in about 1 in individuals. The incident of VMT in patients with diabetic retinopathy, age-related macular degeneration, and other macular diseases is much higher.
It occurs in women slightly regularly than males and can happen at any age, in any race. This technology has been used in vitreo-retina care for years.

This non-invasive diagnostic research can show the retina professional a cross-section view of the vitreous and macula, demonstrating the quantity of involvement and stress on the macula brought on by VMT.
OCT has actually become an exceptionally vital tool in identifying and managing macular issues like VMT.
Vitreomacular Adhesion: What Happens?
Fluorescein angiography is a valuable test that supplies information about the condition of the retina. If VMT is threatening a macular hole, a pars plana vitrectomy is typically advised.
This is a typical retina surgery involving removal of the vitreous. The retina professional surgeon inserts a tiny, needle-like instrument, called a vitrector, into the eye. This instrument will aspirate suck out the vitreous fluid.
The specialist will then fill up the eye with a special saline solution that carefully resembles the natural vitreous fluid in the eye. The surgical elimination of the vitreous alleviates the traction on the macula and with time it will go back to its normal structure and shape.
Jetrea is an intravitreal eye-injected drug to deal with Vitreomacular Adhesions. Jetrea is the very first and only FDA-approved medication for the treatment of VMA and its offers a much needed alternative to vitrectomy. The drug works by dissolving the protein fibers that create the adhesion between the vitreous and the macula.

Dissolving this connection safely completes the detachment of the vitreous from the macula and eases the traction. Last modified: August 16, References.
