Vitreomacular Adhesion (VMA)

Overview

Vitreomacular adhesion (VMA) is defined by perifoveal detachment from the retinal surface but remaining vitreomacular attachment within a 3mm radius of the fovea. There is no detectable distortion of the foveal contour or underlying tissue. Focal adhesion is defined as ≤1500µm where as broad adhesion is defined as >1500µm.

This is a normal finding in the natural course of a PVD.

The macula appearance is unremarkable clinically.

Case Examples

  • Case 1

    A 74 year old Caucasian female with best corrected visual acuity of 6/6 (20/20) in the left eye.

    Spectralis OCT line scan (left macula)

    Spectralis OCT line scan (left macula)

    Attachment between the vitreous and macula is still present at the fovea, however the vitreous can be seen to have detached in the perifoveal area.

  • Case 2

    A 69 year old Caucasian female with best corrected visual acuity of 6/6 (20/20) in the right eye.

    Spectralis OCT line scan (right macula)

    More info

    Attachment between the vitreous and macula is still present at the fovea, however the vitreous can be seen to have detached in the perifoveal area.
