Medical Towers, 2nd floor, Jeppe Street, Johannesburg, South Africa

This excerpt was created in the absence of an abstract.

The clinical features and radiological demonstration of a previously unreported venous malformation of the cavernous sinus are described.

A 13-year-old boy was first seen by an ophthalmologist at one year of age when his mother noticed unequal pupils. At four years of age, his right eye started to protrude and a diagnosis of a cyst behind the right eye was made by a neurologist and ophthalmologist.

At four and a half years, the child was referred to an orthoptist and his findings were as follows:—

Paresis of the right superior oblique and inferior oblique muscles and overaction of the left superior and inferior oblique muscles. Intermittent left hypertropia or right hypotropia for near distance. Right ptosis when tired. The right pupil was slightly larger than the left.
