CASE PRESENTATION: A 22-year-old African gentleman presented with left nasal obstruction and epistaxis for 2 years and was diagnosed with nasopharyngeal carcinoma. [ncbi.nlm.nih.gov]

Additionally, each patient had evaluation for present or past history of ocular infections. [omicsonline.org]

[…] in younger patients 6 and an embolic workup in older patients. [aao.org]

Systemic workup should include an evaluation for those abnormalities associated with acute CRAO. From there your doctor will recommend a course of ocular therapy. [williamsoneyeinstitute.com]

In young patients a vasculitis and/or hypercoagulable workup should be performed. In older patients, an embolic workup should be performed. [eyewiki.aao.org]

[…] carotid disease, and other sources of emboli are classic causes of retinal ischemia (see Table 7.2). 7.1.3 Treatment of Acute Retinal Arterial Ischemia Acute treatment consists of the following: Patients seen acutely should be admitted for immediate workup [neuro-ophthalmology.stanford.edu]

Ophthalmic/retinal vascular occlusion (RVO) suggested an underlying systemic disease and recommended workup of a patient with RVO is suggested in [Table 3]. [ojoonline.org]

Three weeks after treatment, the angiographic abnormalities had resolved, and the retinal and choroidal circulations were normal. Twenty-eight months after treatment, the visual acuity was 20/20 in each eye. [ncbi.nlm.nih.gov]

Abstract Etiological investigation of a 15-year-old boy with left ophthalmic artery occlusion led us to a diagnosis of neurofibromatosis type I as there were numerous large cafe-au-lait spots, axillary freckling, and brain MRI changes consistent with [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]

The etiology of the arterial occlusion (thrombosis, embolus, arteritis, vasospasm) has also been described as affecting outcome.(4,5) Careful classification of the factors involved in an individual case of CRAO is crucial to understanding the natural [uhms.org]

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]

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]

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]

CONCLUSION: Pre-operative angio-architecture understanding and diligent selection of embolic material are helpful in preventing this adverse event. [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]
