BACKGROUND To determine the effect of intravitreal administration of bevacizumab (1.25 mg/0.05 mL) on retrobulbar circulation of the injected and the fellow (uninjected) eyes in patients with neovascular age-related macular degeneration. METHODS In this prospective study, the retrobulbar hemodynamics of 43 patients with neovascular age-related macular degeneration was examined by color Dopple...

BACKGROUND/AIMS A moderately elevated plasma concentration of the sulphur amino acid homocysteine is an independent risk factor for atherosclerotic vascular disease. Many of the risk factors associated with coronary, cerebral, and peripheral atherosclerotic vascular disease are common to retinal vascular occlusive disease but it is unclear whether elevated plasma concentrations of homocysteine ...

PURPOSE To evaluate the effect of dorzolamide on ocular blood flow in normal and glaucomatous eyes. METHODS Twenty-six eyes with documented open-angle glaucoma of 26 patients and 13 normal control eyes of 8 age-matched subjects were included in this study. All eyes underwent color Doppler imaging for measuring peak-systolic velocity, end-diastolic velocity, and resistance index in the ophthal...

PURPOSE To document a case of central retinal artery occlusion after chiropractic treatment. METHODS An 87-year-old man suffered a central retinal artery occlusion immediately after chiropractic neck manipulation. RESULTS A magnetic resonance angiogram showed an atherosclerotic plaque in the ipsilateral carotid artery, which probably shed emboli during cervical joint mobilization. CONCLUS...

We retrospectively studied 46 patients with symptomatic retinal artery occlusion and assessed the pattern and extent of carotid artery disease ipsilateral to the retinal artery occlusion. Ipsilateral internal carotid artery atherosclerotic lesions were virtually limited to the cervical arterial segment; 50% of such lesions were plaques or stenoses of less than or equal to 60%, whereas 15% of th...

Purpose. To report a case report of one patient suffering from retinal artery occlusion secondary to Buerger's disease, in order to raise awareness to this etiology in the differential diagnosis of retinal artery occlusion. Methods. A retrospective case report of a patient with retinal artery occlusion secondary to Buerger's disease. Data retrieved from the medical records included exposure, co...

BACKGROUND While peribulbar anesthesia is generally safe, a remote risk of retinal vascular accident exists and its routine use should be done with caution. OBJECTIVE To report a case of central retinal artery occlusion (CRAO) that occurred within 24 hours of routine uneventful phacoemulsification cataract surgery using peribulbar anesthesia. We share our experience of a 45-year old man who u...
