horseshoe tear

horseshoe tear

A type of retinal tear in which a strip of tissue is torn from the retina. The tear commonly follows a vitreous detachment in which the vitreous adheres to the retina and pulls it from the point of adherence during or just after an abrupt eye movement. This type of retinal tear is particularly dangerous since it is often a precursor to a retinal detachment.
