Livedoid vasculopathy (LV) is characterized by a long history of ulceration of the feet and legs and histopathology indicating a thrombotic process. We report a case of acute central retinal artery occlusion in a 32-year-old woman who had LV. She showed no discernible laboratory abnormalities such as antiphospholipid antibodies and no history of cerebrovascular accidents. Attempted intra-arteri...

OPINION STATEMENT Central retinal artery occlusion (CRAO) is an ocular emergency and is the ocular analogue of cerebral stroke. It results in profound, usually monocular vision loss, and is associated with significant functional morbidity. The risk factors for CRAO are the same atherosclerotic risk factors as for stroke and heart disease. As such, individuals with CRAO may be at risk of ischemi...

A case is presented of a 70-year-old white male who underwent a bilateral cosmetic lower lid blepharoplasty with fat removal. He subsequently developed a right orbital haemorrhage which resulted in the occlusion of the central retinal artery. The patient had no light perception with his right eye for approximately 1 hour, but vision was eventually restored to 20/20 after emergency therapeutic m...

Dear Editor, Central retinal artery occlusion (CRAO) typically presents with a retinal “cherry red spot”. In CRAO, infarction of the retinal nerve fi bre layer renders the retina opaque. The fovea, where this layer is absent, retains its normal orangered colour due to perfusion from the underlying choroidal vessels, resulting in the appearance of the “cherry red spot”. Retinal survival time has...

Central retinal artery occlusion (CRAO) is an uncommon entity in ophthalmic practice. Reported etiologies are numerous, and involve systemic and ocular preexisting pathologies. A traumatic etiology for CRAO is rare with anecdotal reports and poor visual outcomes. No specific treatment guidelines exist to date. We report a case of traumatic CRAO in a young female without any systemic vascular ri...

PURPOSE The aim of this study was to determine whether a significant correlation exists between the scotopic and photopic components of electroretinograms (ERGs) and the degree of circulation disturbances caused by a central retinal artery occlusion (CRAO). DESIGN Observational clinical study. PARTICIPANTS Sixteen patients with a CRAO (16 eyes). METHODS The circulatory disturbance in eyes...

Ocular pneumoplethysmography and ophthalmodynamometry measure ophthalmic arterial system pressures to assess noninvasively the hemodynamics of the carotid system. A previously unreported circumstance in which these tests complement one another is central retinal artery occlusion. Typically, the ipsilateral retinal artery pressure, measured by ophthalmodynamometry, is greatly decreased or is zer...

A case of central retinal artery occlusion in a patient with a 10-year history of unexplained thromboembolic disease due to a secondary hypercoagulable state is presented. Ophthalmological examination led to the final diagnosis.

The antiphospholipid syndrome (APS) has been related to venous and arterial thrombosis of large and small vessels. Ocular vessels can also be involved causing transient visual loss, diplopia, ischemic optic neuropathy and central artery and venous occlusion. We describe here a case of antiphospholipid syndrome with occlusion of central retinal artery and vein to call the attention to this diagn...
