  Causes of OIS include arterial hypertension, atherosclerosis, diabetes, aortoarteritis and other vascular diseases. Clinical features depend on the extent, nature, and site of vascular involvement as well as the concurrent pathology. [ncbi.nlm.nih.gov]

(III, good quality, strong recommendation) Acute, symptomatic OAO or CRAO from embolic etiologies should prompt an immediate referral to the nearest stroke referral center for prompt assessment for consideration of an acute intervention. [aao.org]

Subsequent management is directed toward identification and treatment of any underlying disease, with etiologic considerations being similar to those for central retinal artery occlusion. [healio.com]

Pathophysiology Blood supply to the retina originates from the ophthalmic artery, the first intracranial branch of the internal carotid artery that supplies the eye via the central retinal and the ciliary arteries. [emedicine.medscape.com]

Pathophysiology The central retinal artery supplies the inner retina. Occlusion of the retinal arteries results in ischemia of the inner retina. When the inner retina is damaged, it first becomes very edematous. [eyewiki.aao.org]

New techniques for enhanced imaging of the choroid will certainly add to the understanding of the pathophysiology [ 23 ]. However, these techniques should be correlated with assessment of the ophthalmic artery. [omicsonline.org]

The possible mechanisms contributing to the loss of vision are discussed and preventive strategies are suggested to reduce the incidence of this complication. [ncbi.nlm.nih.gov]

This case highlights the importance of early diagnosis and prompt treatment of giant cell arteritis in order to prevent the blinding complications like ophthalmic artery occlusion, and in case of unilateral involvement, to save the other eye. [ijmr.org.in]
