Vitreomacular Adhesion and Vitreomacular Traction
Introduction:
Vitreomacular adhesion (VMA) is an OCT finding. It represents a perifoveolar detachment of the cortical vitreous from the underlying retina with part of the vitreous remaining attached at the macula and elsewhere in the eye. The underlying macular retina is normal. It is almost always a normal finding, representing the initial evolution of a normal posterior vitreous detachment. Vitreomacular traction (VMT) is present when perifoveolar vitreous detachment is accompanied by retinal morphological changes arising from traction of the vitreous on the retina. There is no known racial predilection for VMT. VMT is more common in women (about 65%), with most patients in their sixth or seventh decade of life
Clinical Features:
Patients may complain of decreased central vision with metamorphopsia. On examination, there may be preretinal fibrosis, epiretinal membrane formation and blunting or alteration of the foveal reflex with a pseudo-hole appearance.
