Pathogenesis of intraocular hypertension in cases of arteriovenous aneurysm

INTRAOCULAR hypertension is a fairly constant symptom in patients with aneurysm of the cavernous sinus and the internal carotid artery. We have found it in each of five patients recently examined. Three times it was unilateral and affected only the eye on the same side as the lesion ; twice it was bilateral. The present work is the report of a new case of arteriovenous aneurysm complicated by intraocular hypertension. The use of recent techniques—measurement of the episcleral venous pressure, measurement of the resistance to the aqueous flow, and calculation of the volume of this flow—has thrown some light on the mechanism of intraocular hypertension. REPORT OF A CASE M. J., aged 17 years, was wounded in June, 1950, in a road accident. He sustained a fracture of the skull, with depression of the right frontotemporal region. His condition steadily improved in the weeks following the accident. Recovery seemed complete, but
