| persistent anterior hyperplastic primary vitreous | A unilateral congenital abnormality occurring in full-term infants; characterised by a retrolental fibrovascular membrane formed by persistent primary vitreous with remnants of the hyaloid artery and tunica vasculosa lentis; associated with leukokoria, microphthalmos, shallow anterior chamber, and elongated ciliary processes. (05 Mar 2000) |
