Rarefaction and partial tears of the retina adjacent to blood vessels (paravascular retinal rarefaction and paravascular retinal tears) were studied to determine their morphologic features, incidence, distribution, and relationship to the vitreous body. Paravascular retinal rarefaction was seen adjacent to retinal venules and arterioles. This lesion was associated with an attached posterior vitreous. Paravascular retinal tears occurred in clusters between the equator and the posterior border of the vitreous base. These partial-thickness tears were always associated with posterior vitreous detachment. Both lesions appear to be due to vitreal traction at the site of paravascular vitreoretinal attachments. Such attachments are considered normal anatomic variations and probably explain the occurrence of clinically detectable full-thickness retinal tears in areas of normal appearing retina and why these tears commonly involve retinal blood vessels.
