COMMENT. Remnants of pupillary membranes are very common occurring in 95% of normal newborn babies.3 Early development of the crystalline lens at about the sixth week coincides with the growth of the tunica vasculosa lentis which nourishes it. The anterior portion of this is continuous with the pupillary membrane which draws its blood supply from the capillaries which arise from the branches. Persistent tunica vasculosa lentis is a congenital ocular anomaly. It is a form of persistent hyperplastic primary vitreous (PHPV).. It is a developmental disorder of the vitreous.It is usually unilateral and first noticed in the neonatal period. It may be associated with microphthalmos, cataracts, and increased intraocular pressure.Elongated ciliary processes are visible through the dilated.

So-called persistent tunica vasculosa lentis, or a fibroblastic sheath behind the crystalline lens, is known to occur sporadically. Usually the condition is discovered a few days after birth in an infant born at full term, but the correct diagnosis is often not established until the eyes are examined pathologically after removal because of a clinical diagnosis of retinoblastoma Persistent Hyperplastic Primary Vitreous.

Persistent hyperplastic primary vitreous is a developmental malformation of the eye due to the presence of hyperplastic retrolental fibrovascular membrane with persistence of the posterior portion of the tunica vasculosa lentis and hyaloid artery. This abnormality is usually unilateral and associated with microphthalmia, cataract, and glaucoma Posterior tunica vasculosa lentis supplies the posterior lens Retinal vascular development begins during 16th week: mesenchymal cells next to hyaloid artery form capillary network, then form arteries and veins; vessels grow centrifugally from optic disc, reach nasal ora serrata during 8th month and temporal ora 1-2 months late (B) Persistent hyperplastic tunica vasculosa lentis in a hound dog. The surrounding mat of blood vessels are perfused and posterior capsular cataract is present. Persistent hyaloid remnants, when the sole abnormality, are characterized by a posterior polar cataract with blood vessels extending from the optic nerve head to the polar posterior. The intravitreal hyaloid vessels arise partly from the tunica vasculosa lentis and attach to the avascular retina between the ora and equator . They reach a peak at 10 weeks' gestation and undergo apoptosis at 5-6 months' gestation, completing atrophy by the eighth month . The failure of these vessels to regress completely leads to the.
