“…11,12 Thrombophilia, high blood viscosity, systemic vasculitis, or autoimmune diseases are other systemic risk factors. [12][13][14][15] Our patient has also several risk factors such as hypertension, atherosclerosis, smoking, and positive family history despite of his relatively young age.…”

Ophthalmic artery provides blood supply of the eye that is a branch of internal carotid artery (ICA). ICA occlusive disease (ICAOD) causes reduction in perfusion pressure of the ophthalmic artery and its branches. So, unilateral blurred low vision can be seen due to chronic progressive ocular ischemia. We presented a subject with low vision and retinal arterial narrowing, arteriovenous nipping, retinal hemorrhages, roth spots, and loss of foveal light reflex were present in the fundus. Macular edema were seen with optical coherence tomography (OCT) and delay in arterial filling, capillary dropout, and foveal late-phase leakage were seen with fundus fluorescein angiography (FFA).Our patient has several risk factors such as hypertension, atherosclerosis, smoking, and positive family history despite of his relatively young age. In this case report, we aimed to take attention the possibility of unilateral chronic low vision due to ICAOD in a young subject.

“…This complies with the suggested procedures. Amaurosis fugax is most usually associated with significant internal carotid artery atherosclerosis, yet there should still be some concern regarding atheroembolism from the aorta or its branches, including the subclavian or brachiocephalic arteries [10,11].…”

In this case report, we highlight a case of a 24-year-old primigravida who suffered a sudden and painless loss of vision and headache in the immediate postpartum period. Vision loss was transient and remarkable. Her brain magnetic resonance imaging revealed vasogenic edema in parieto-occipital white matter, suggestive of posterior reversible encephalopathy syndrome. Posterior reversible encephalopathy syndrome is a clinical-radiological entity, having hemodynamic catastrophe also known as reversible posterior cerebral edema syndrome. It tends to occur during pregnancy complicated by eclampsia. Hypertension and a hypercoagulable tendency tend to engulf the entire homeostasis into its deadly clutches sending the autoregulation into a frizzy. It presents with a gamut of red flags like headache, seizures, encephalopathy, amaurosis fugax, cortical visual disturbances, and even blindness. Clinical improvement was seen with supportive treatment in this patient. Thus, timely diagnosis and intervention help reverse the dire consequences.

“…Amaurosis fugax describes monocular or binocular loss of vision, typically lasting seconds to minutes. 1,2 This symptom is generally caused by a manifestation of thromboembolic event in which atherosclerotic debris originating in the carotid artery or the aortic arch temporarily disrupts blood flow in the branch or central retinal arteriolar network. 2,3 Immediately treating a patient with amaurosis fugax in whom aortic or carotid atherosclerosis is detected with an anti-platelet agent and a statin are consistent established guidelines.…”

Introduction: Amaurosis fugax is caused by an abrupt reduction of blood flow to the retina. Determining the etiology of amaurosis fugax should ensure proper management. Case Report: A 47-year-old female patient who had the first episode of amaurosis fugax in her right eye was referred to our hospital. The amaurosis fugax resolved spontaneously, however, we found a 3 mm long stenosis at her right ophthalmic artery during magnetic resonance angiography. She had clinical histories of untreated hypertension and dyslipidemia. Transient ischemic attack (TIA) was suspected and unfractionated heparin, aspirin, antihypertensive agent, and statin were given. Treatments were maintained, the symptoms had not recurred in the following 6 months after the event. Discussion: Stenosis of the ophthalmic artery is very rare. It occurs in approximately 2% of patient suffering from amaurosis fugax. In our case, stenosis of the right ophthalmic artery due to thromboembolism might cause retinal ischemia leading to a transient visual loss. Conclusion: This case suggests stenosis of ophthalmic artery as the cause of amaurosis fugax. Keywords: amaurosis fugax, ipsilateral, ophthalmic artery, stenosis
