This 20 year old man presented in September,
1995 with a chief complaint of intermittent diplopia and difficulty focusing
his leftward gaze during the past month. His past medical history included a
tonsillectomy and adenoidectomy at age 5 years, a resection of a posterior
fossa dermoid at age 10 followed by drainage of a subdural hematoma a few
months later. He has been healthy since that time.
Examination revealed no abnormalities in his eye movements. Both his visual acuity and peripheral vision (by Goldman perimetry studies) were normal. The remainder of the physical exam was unremarkable. Standard serum laboratory values were normal and there was no increased prolactin.
