—Dr. Brockhurst has raised an important question concerning whether vitreous is or is not attached to the posterior edge of a retinal dialysis. He believes that if this occurs, it must be a "medical curiosity." We would disagree. First, it would seem relevant to note that multiple areas of attachment of formed vitreous to retina at or posterior to the equator have been described in normal, untraumatized eyes by Grignolo.1 Irvine2 has shown "sucker feet" of formed vitreous attached to the posterior retina, and, very recently, Spencer and Foos3 have reviewed the paravascular vitreoretinal attachments which may occur at or posterior to the equator.
