Child with extreme congenital proptosis and microcephalus

Mark, Leonard Portal

Watercolour drawing of the head and face of a child aged one day, showing a condition of extreme congenital proptosis and microcephalus. More than the anterior half of the globe of the eye on each side was quite uncovered by the eyelid. There was great chemosis, and very considerable opacity of both corneae. The eyes could be moved independently of each other. Though the eyelids could be drawn over the eyes with difficulty, they retracted again at once when not held in position. The prominence of the eyes seemed largely due to the fact that the orbital plates of the frontal bones were only partially developed.
