Ultrasonography suggested the diagnosis of cataract associated with persistent fetal intraocular vasculature in a 26-day-old sambar deer. The deer was ill and died despite intense critical care. Globes were removed. Histological characteristics of persistent fetal vasculature and secondary cataract
A 17-month-old girl referred for a suspected ciliary body medulloepithelioma was found to have persistent fetal vasculature. Fluorescein angiography showed perfused hyaloid artery posterior tunica vasculosa lentis with brittle star appearance and nonperfused anterior pupillary membrane. Ultrasound
Persistent hyperplastic tunica vasculosa lentis and persistent hyperplastic primary vitreous are congenital ocular anomalies that can lead to cataract formation. A line of insertional mutant mice, TgN3261Rpw, generated at the Oak Ridge National Laboratory in a large-scale insertional mutagenesis
Two domestic shorthair cats (6 and 9 months old) were presented for examination of ocular opacities. One cat had bilateral persistent pupillary membranes, unilaterally accompanied by persistent hyperplastic tunica vasculosa lentis, persistent hyperplastic primary vitreous (PHTVL/PHPV), and cataract.
Ultrasonography was performed on a Basset hound and a Doberman clinically suspected of persistent hyperplastic tunica vasculosa lentis/persistent hyperplastic primary vitreous. In both dogs, hyperechoic lenses with a triangular-shaped echodense structure retrolentally were visible, and a very thin
The objective of this study was to describe the clinical, histologic and immunohistochemical features, the surgical treatment, and outcome of a cataract secondary to persistent hyperplastic tunica vasculosa lentis/persistent hyperplastic primary vitreous (PHTVL/PHPV) in a dog. A 4-month-old male
A 2-year-old Basset hound with unilateral persistent hyperplastic tunica vasculosa lentis and primary vitreous is described. There was leukokoria in the left eye, caused by bluish-white polar densities and haemorrhagic discoloration in the nucleus of the lens. Ultrasonographic examination of the eye
A 3-month wild rabbit was presented for examination of ocular opacities in the left eye. A complete bilateral ocular examination including slit-lamp examination, indirect ophthalmoscopy, tonometry, and ultrasound biomicroscopy was performed. Biomicroscopy of the lens of the left eye showed a
This report provides transmission electron microscopic observations on the early pathogenesis of persistent hyperplastic tunica vasculosa lentis/persistent hyperplastic primary vitreous (PHTVL/PHPV) in affected canine fetuses at days 28-44 postcoitum. The retrolental tissue by which this anomaly is
Observations on (postnatal) persistent hyperplastic tunica vasculosa lentis/persistent hyperplastic primary vitreous (PHTVL/PHPV) in man and dog have been published previously. Up to the present, no evidence on the etiology of this entity was available. The hereditary occurrence of the disease in
This study provides transmission electron microscopic observations on the early morphogenesis (from days 25-35 post coitum) of the canine posterior lens capsule, the tunica vasculosa lentis (TVL) posterior and the anterior part of the vitreous body. The presence of an anlage of the posterior lens
