Vitreomacular Traction Syndrome – VMT

Vitreomacular traction syndrome, or VMT, is an eye condition that can cause symptoms ranging from mild blurry vision, to distorted and darkened central vision.

Vitreomacular Traction Syndrome - VMT

The center of the eye is filled with vitreous humor — a clear, gel-like substance that lies between the lens (near the front of the eye) and the retina, the light-sensitive, inner lining of the inside of the eye. The vitreous contains millions of tiny intertwined fibers that are connected to the retina from birth and throughout our younger years.

As we age, the vitreous slowly liquefies, shrinks and gradually separates from the retinal surface. This normal aging process is called Posterior Vitreous Detachment, or PVD.

Sometimes, the vitreous gel’s fibers adhere in an abnormally strong manner, not allowing the vitreous to properly pull away from the macula, the part of the retina responsible for central vision. The resulting “tug” on the macula causes changes in its shape and anatomy, preventing its ability to properly process incoming light rays. This condition, Vitreomacular Traction, can make it difficult to do daily tasks that require sharp vision, such as reading or watching television.

Often, the adherent vitreous will free itself and the macula will return to its normal condition. In rare cases, the undo stress at the point of the vitreous adhesion creates a macular hole, further distorting and darkening the central vision. If this happens, surgical intervention may be required in order to reduce the likelihood of permanent vision loss.

Mark Erickson

Working as an Ophthalmic Photographer since 1988, Mark Erickson has examined and photographed virtually every type of eye condition there is through various high-powered microscopes and cameras. This experience has given him a unique and intimate understanding of the eye and its various anatomical structures, diseases and surgical procedures. In 1998, Mark started coupling this medical photography experience with his artistic and creative abilities. The result is a vast gallery of various eye anatomy, eye conditions & diseases and surgical illustrations. Mark’s work has been published on the front cover of numerous, top eye care industry magazines and books. His work frequently illustrates the front cover of industry journals. Mark’s work has been commissioned by National Geographic, Bausch & Lomb, Johnson & Johnson and Transition Lenses, to name a few. Mark Erickson’s artwork and story were published in The National Association of Photoshop Professionals monthly publication, “Photoshop User” and “Layers” magazines. Mark now focuses his creative energy on his website,, and creating and licensing stock and custom ophthalmic illustrations and animations for use in pharmaceutical marketing, legal cases, product marketing, websites and patient education materials.
