Eyes

Persistent Fetal Vasculature (PFV), previously known as Persistent Hyperplastic Primary Vitreous (PHPV) is a rare developmental malformation of the eye characterized by the presence of a vascular membrane located behind the lens.

A congenital cataract is a cloudy or opaque area in the (normally clear) lens of the eye or in the surrounding membranes of the lens present at birth.

Dacryocystocele is a rare congenital midface anomaly caused by obstruction of both proximal and distal ends of the nasolacrimal duct.

Exophthalmos may be defined as an eye that is protruding anterior to the plane of the face to a greater extent than is typical, or in other words, bulging out of the orbit.

Eye development occurs between week 3 and 10 of gestation. Fetal orbital and eyes anomalies can already be detected in the first trimester, but more commonly at the second trimester scan.

Coloboma is a rare eye malformation that affects 1,4/10,000 births. It refers to the absence of normal tissue in the central part of the eye.
