The causes, evaluation, and controversial treatment of traumatic hyphema are the subject of this review of the recent literature. General protective mechanisms of the eye against trauma, theories as to the egress of anterior blood, complications of hyphema, and prognostic factors are discussed.

Scintillating scotomas are frequently seen without an associated headache and in general should be considered a benign symptom. In this series of 10 patients with an age range from 25 to 72 years, there were 7 female and 3 male patients. With an average follow-up of 1 1/2 years there was no patient who subsequently developed migraine headaches or any persisting neurologic sequelae.

Characteristic ultrasonsographic patterns of retinal detachment in a variety of clinical circumstances are demonstrated and discussed. Uncomplicated retinal detachment consists of ultrasonically detected retinal detachment without associated pathology in the vitreous, subretinal space, or choroid. ⋯ Acoustic diagnostic criteria for differentiation of associated conditions in complicated retinal detachments are demonstrated and discussed. High resolution A-scan and B-scan ultrasonography provides a method for detection and diagnosis of retinal detachment, associated ocular pathology, and simulating conditions.

The effect of systemic hypotension during cardiopulmonary bypass on intraocular pressure and visual function in humans.
The effect of controlled systemic hypotension on intraocular pressure (IOP) and visual function was measured in a group of 12 patients undergoing extracorporeal perfusion during cardiovascular surgery. When venous pressure was controlled, intraocular pressure was noted to fall following a fall in the systemic blood pressure. There was a return of IOP toward normal levels with recovery of the systemic blood pressure. Systemic hypotension of 25 to 100 mm Hg for up to 201 minutes in the presence of hemodilution and hypothermia was not associated with any functional or morphologic change in ocular function.
