Myopic Vitreomacular Traction Syndrome

Abstract

Vitreomacular traction is the pathogenesis of a group of traction maculopathies, such as macular holes, macular pucker, tractional cystoid macular oedema, vitreomacular traction syndrome, and myopic traction maculopathy. Myopic traction maculopathy (MTM), also known as myopic foveoschisis typically occurs in highly myopic eyes. Its prevalence has been reported to range from 8% to 34% in highly myopic eyes. It may be caused by premacular traction of vitreous cortex or posterior ectasia which is associated with posterior staphyloma in high myopia, resulting in a “stretch retinoschisis”. A degenerative process involving the posterior retina may be another factor associated with myopic foveoschisis.
