Central retinal artery occlusion is a rare event and the site of obstruction is not usually visible on clinical examination; therefore, the precise cause is often speculative. It is currently believed that the majority of central retinal artery obstruction is caused by thrombus formation. Atherosclerosis is implicated as the contributory event in most cases, although congenital anomaly of the c...

Objective: To report a case of iatrogenic central retinal artery occlusion after embolization and surgical resection of carotid body paraganglioma. Methods: Case report Results: One adult female patient presented with persistent unilateral visual loss after embolization with Embosphere® and Contour® microparticles of carotid body tumor. Fluorescein angiography revealed intraluminal microspheres...

BACKGROUND A 75 year old lady presented with acute central retinal artery occlusion and contralateral cotton wool spots. CASE PRESENTATION General physical examination and investigations led to a diagnosis of CREST syndrome; however, association of central retinal artery occlusion with CREST syndrome is not well known. While diabetes, systemic hypertension, carotid atherosclerosis and cardiac...

Doppler ultrasound was used to detect possible flow changes in the carotid arteries of patients with central retinal artery and vein occlusion. Twenty-three patients with central retinal artery occlusion (mean age 56, SD 11, years) were examined 4 to 48 months after the development of the occlusion and compared with age and sex matched control subjects with no history of any disease known to be...

I read with great interest the excellent study by Kang et al. in the March 2011 issue. In the context of their study, this short communication is intended to address an aspect of the ocular pathology in diabetic retinopathy. Diabetic retinopathy is among the leading causes of blindness in the working population in developed countries. However, the exact etiology and the mechanism of disease pro...

(1) The role of the central retinal artery in the blood supply of the optic nerve. (2) The existence of a central artery of the optic nerve. (3) The existence and extent of the anastomoses between the central retinal artery and the arteries surrounding the optic nerve. Francois and Neetens (1963), in their latest publication on the subject, have raised certain controversial issues which require...

An 86 year old woman experienced a sequential bilateral loss of vision over a period of less than 24 hours. Clinical findings and complementary studies suggested a bilateral atherogenic embolic event. Initially, she presented a superior branch retinal artery occlusion in her right eye followed by a central retinal artery occlusion with cilioretinal artery sparing in her left eye. Some conservat...
