Persistent hyperplastic primary vitreous in a family with osteoporosis-pseudoglioma syndrome

Abstract

We had the opportunity to investigate the early abnormalities of the eyes in a family with osteoporosis-pseudoglioma syndrome. This syndrome combines severe premature osteoporosis with a bilateral eye disorder, leading to early onset blindness. Using colour doppler imaging in the 4-month-old girl from this affected family we demonstrated persistent hyperplastic primary vitreous in both eyes. Her brother's eyes had developed a partially calcified undefined mass. Our observation supports the hypothesis, that the disease gene may encode a matrix protein expressed in bone and eye.
