Central Retinal Artery
(1) The cocainized eye tolerates subconjunctival injections of crystalline penicillin in doses of 100,000 untts at 12 hourly intervals and doses ranging from 200,000 to 500,000 units at 24 hourly intervals. (2) With doses of 500,000 units in 0 5 ml. of adrenalin solution 1 :1,000, at 24 hourly intervals, preliminary results in hypopyon ulcer are distinctly promising, both as to a satisfactory e...
متن کاملMorphometric characteristics of central retinal artery and vein endothelium in the normal human optic nerve head.
PURPOSE This study documents the morphometric features of arterial and venous endothelia in the different laminar regions of the normal human optic nerve head and speculates on the hemodynamic characteristics of the central retinal artery (CRA) and central retinal vein (CRV). METHODS Twenty normal human eyes were used. Microcannulation techniques were used to label the cytoskeleton and nuclei...
متن کاملSimultaneous central retinal artery occlusion and optic nerve vasculitis in Crohn disease
Purpose To describe a case of Crohn disease presenting as occlusive vasculitis resulting in a central retinal artery occlusion (CRAO) in one eye and transient ischemic optic neuropathy in the fellow eye. Observations An 18-year-old patient recently diagnosed with biopsy-proven Crohn disease presented with CRAO OD after a previous episode of transient visual loss OS. Extensive workup was negat...
متن کاملCentral Retinal Artery Occlusion Masquerading as Branch Retinal Artery Occlusion
Dear Editor, Retinal artery occlusion (RAO) is characterized by attenuated arterioles and ischemic retinal opacity, which suggest retinal infarction. Branch RAO (BRAO) has a more favorable prognosis than central RAO (CRAO). CRAO and BRAO can be differentiated based on the isch-emic retinal opacity area, location of the attenuated vessels , and a cherry-red spot [1]. However, we encountered a ca...
متن کاملCentral retinal artery pressure and carotid artery stenosis
The central retinal artery (CRA), which can be non-invasively examined with ophthalmoscopy, may be regarded as an extracranial part of the cerebrovascular system. Assessment of CRA pressure may be of help in assessing the impediment of the intracranial blood circulation in patients with a carotid artery stenosis (CAS). The aim of this study was to explore the potential associations between dias...
