Intraocular adipose tissue was found in ten eyes, in each of which there was evidence of persistent hyperplastic primary vitreous. In every case this was associated with other ocular congenital anomalies such as microphthalmos, persistent hyaloid vessels, cataract, and/or an incompletely developed anterior chamber angle. One of these eyes also contained intraocular cartilage; the patient from whom the eye was obtained was otherwise normal.
