Incontinentia pigmenti (Bloch-Sulzberger syndrome) and retinal changes.

Incontinentia pigmenti is associated with various anomalies in 80% of cases. Among the most important are the ocular abnormalities and more particularly a retrolental mass with detachment of a dysplastic retina. At the basis of this manifestation are retinal vascular changes, characterised at first by ectatic tortuous veins and arteriovenous anastomoses as well as by aneurysmal-like dilatations.
