Clivus_Chordoma | Shirley H. Wray, MD, PhD, FRCP | This 46 year old patient had at age 6, a tendency for the left eye to wander out. Her face photograph at that age shows an exotropia and at age 7, a year later, the exotropia was not quite as prominent. It was assumed that the exotropia was due to a non-paralytic strabismus. Past History: At age 1 f... | Esotropia; Abduction Weakness; Sixth Nerve Palsy; Clivus Chordoma; Chordoma |
