artery in the neck. Obviously the pressure is not always so low and will depend on the collateral circulation which may be much better to the eye than to the brain. On the contrary, one might expect to find a near-zero low diastolic retinal artery pressure in some patients with a stroke without carotid artery occlusion but with a retinal artery stenosis or thrombosis (near-zero low pressure is ...

Purpose To report a case of bilateral central retinal artery occlusion with both anterior and posterior ischemic optic neuropathy. Observations A 65-year-old Caucasian woman presented with acute respiratory distress syndrome and septic shock. After treatment with vasopressors and prolonged prone positioning, she was noted to be bilaterally completely blind on hospitalization day 12. Evaluatio...

PURPOSE to report a case of branch retinal artery occlusion in the acute phase, using optical coherence tomography to evaluate the morphologic changes. A 27 year-old man had a sudden superior scotoma in the right eye, with fundus examination compatible with inferior temporal branch retinal artery obstruction. The optical coherence tomography revealed increase in thickness and hyper-reflectivity...

INTRODUCTION The vascular complications of herpes zoster are well recognised, however, there are few reports of central retinal artery occlusion. Central retinal artery occlusion following herpes zoster ophthalmicus is poorly recognised. This is likely due to the difficulties in obtaining tissue for histopathology to establish causality. We report a case of central retinal artery occlusion and ...

We report a case of bilateral retinal artery occlusion due to mitral valve prolapse. Most patients with retinal ischaemia in whom it is found have not been previously known to have it. Since it is a common condition it would seem essential that it be included in the differential diagnosis of amaurosis fugax and retinal artery occlusion if future ischaemic events are to be prevented. All patient...
