This is a picture of the vitreous showing an adherent posterior hyaloid. This is represented by the thickened hyper-reflective band that is anterior to the retina. When the posterior hyaloid is attached to the retina, it may result in a mild vitreomacular traction.
Vitreomacular adhesion is a condition of concern as vitreous humour adheres to the retina in an abnormally strong manner. There is evidence that symptomatic VMA can contribute to the development of several ocular pathologies.
Of particular concerns are macular hole, macular pucker, age-related macular degeneration, diabetic macular edema, retinal vein occlusion, and diabetic retinopathy.
