Acute visual loss is rarely caused by a heart condition. This manuscript transcribes a case report of a 36-year-old patient with a 2-year history of aortic valve replacement due to bicuspid aortic valve endocarditis that presents to the emergency department with an acute right eye visual loss. After ophthalmologic investigation identified a central retinal artery occlusion, a transthoracic echocardiography was performed to search for a possible cardiac embolus, despite the patient presenting INR values of 2-2.5 for the last year. A mitral-aortic intervalvular fibrosa pseudoaneurysm was identified. A transoesophageal echocardiography was then performed, identifying a small clot logged inside the pseudoaneurysm that protruded to the left ventricle outflow tract. After INR-adjusted warfarin treatment to levels between 3 and 4, the pseudoaneurysm was surgically closed. This is a rare case since the likely source of embolism to the central retinal artery was the thrombus logged inside the pseudoaneurysm despite a standardly accepted therapeutic INR.

Background. To report a patient with central retinal artery occlusion (CRAO) associated with sildenafil overdose. Case Presentation. A forty-two-year-old male presented three hours after sudden painless visual loss in the right eye. BCVA was counting finger in two meters, and relative afferent pupillary defect was positive. Fundus examination revealed retinal whiteness except in a limited area of papillomacular bundle and cherry red spot. He consumed two 100 mg film-coated sildenafil tablet (Vizarsin, Krka, d.d., Novo mesto, Slovenia) twelve hours apart, and the last one was six hours before visual loss. He was diagnosed with CRAO with cilioretinal artery sparing. Although we did not find any emboli, anterior chamber paracentesis was done. Four weeks later, BCVA improved to 20/80, with resolving of retinal edema. Cardiovascular, carotid arteries, and neurologic evaluations were negative for any predisposing factor. Conclusion. CRAO is a vision threatening condition that might be associated with the overdose of sildenafil.

Almost two-thirds of patients with giant cell arteritis (GCA) develop ocular symptoms and up to 30% suffer permanent visual loss. We review the three most common mechanisms for visual loss in GCA, describing the relevant ophthalmic arterial anatomy and emphasising how ophthalmoscopy holds the key to a rapid diagnosis. The short posterior ciliary arteries supply the optic nerve head, while the central retinal artery and its branches supply the inner retina. GCA has a predilection to affect branches of posterior ciliary arteries. The most common mechanism of visual loss in GCA is anterior arteritic optic neuropathy due to vasculitic involvement of short posterior ciliary arteries. The second most common cause of visual loss in GCA is central retinal artery occlusion. When a patient aged over 50 years has both anterior ischaemic optic neuropathy and a central retinal artery occlusion, the diagnosis is GCA until proven otherwise, and they should start treatment without delay. The least common culprit is posterior ischaemic optic neuropathy, resulting from vasculitic involvement of the ophthalmic artery and its pial branches. Here, the ophthalmoscopy is normal acutely, but MR imaging of the orbits usually shows restricted diffusion in the optic nerve.

Retinal Artery

A bee sting can lead to an extremely rare case of visual loss caused by central retinal artery occlusion (CRAO). In this study, we report a 66-year-old healthy woman who was referred to our Eye Center because of visual loss, which had occurred after bee sting 2 days earlier. The visual acuity was no light perception (NLP). Examination revealed left eyelid edema, conjunctiva congestion, a 6-mm fixed pupil, scattered retinal hemorrhage, and white-appearing ischemic retina with one small area of the normal-appearing retina temporal to the optic disk. Fundus fluorescein angiography revealed CRAO with one cilioretinal artery sparing. Her systemic workup revealed hypersensitivity, hypercoagulable state, myocardial damage, and hepatic damage. After topical and systemic treatments, the visual acuity was still NLP with improved systemic workup. In brief, CRAO may occur after bee sting, and visual acuity should be monitored for early diagnosis.
