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.

A 54-year-old male patient applied to our clinic with a sudden and painless loss of vision in his right eye. He was suffering from COVID-19. His best-corrected visual acuity of the right eye was finger counting from 30 cm. The fundus examination revealed the presence of a ‘cherry-red spot’ appearance in the right eye. In optical coherence tomography imaging, hyper-reflectivity was observed in the inner retinal layers as well as increased retinal thickness in the right eye. In fundus fluorescein angiography, delayed arterial filling and prolonged arteriovenous transit time were observed in the right eye. The patient was diagnosed with central retinal artery occlusion after the COVID-19 infection. In this study, we report this case and its management.

Purpose: This report describes a patient with bilateral, sequential central retinal artery occlusions (CRAOs) due to infective endocarditis (IE). Methods: A case report is presented. Results: A 35-year-old man with IE who recently completed a course of intravenous antibiotic therapy presented with sudden right-eye vision loss. Examination revealed hand motion vision, a cherry-red spot in the macula in the right eye, and an embolus in the inferotemporal arcade of the left eye. The diagnosis of right-eye CRAO secondary to IE was made, with the presumed source being his dental caries. The patient was admitted with plans for aortic valve replacement and dental extraction. During his hospitalization, the patient suffered from a CRAO in his left eye, resulting in bilateral loss of vision. Conclusions: IE can have severe embolic complications; prompt diagnosis and treatment medically and surgically are necessary to reduce further morbidity and mortality.

Central retinal artery occlusion (CRAO) is a rare but blinding disorder. We present a case of a 81-year-old woman with multiple cardiovascular comorbidities admitted to the emergency department due to sudden, painless vision loss on left eye (oculus sinister (OS)) on awakening. The patient also reported long standing fatigue associated with effort that started 4 months before admission. She presented best corrected visual acuity of counting fingers OS. Funduscopy OS revealed macular oedema with cherry red spot pattern. Blood cultures came positive for Streptococcus gallolyticus in the context of a bacteremia and native mitral valve vegetation identified on transoesophageal echocardiography. CRAO of embolic origin was admitted in the context of an infective endocarditis. CRAO can be the first manifestation of a potentially fatal systemic condition and thus multidisciplinary approach is warranted with close collaboration between ophthalmologists and internists in order to provide proper management and the best possible treatment.

Immunodeficiency Syndrome

Purpose In patients with acquired immunodeficiency syndrome (AIDS), disturbances in the circulation of retinal vessels are mostly encountered at the microvascular level. Rarely observed large retinal vessel occlusions frequently affect retinal veins. Methods A 32-year-old woman was admitted to the authors' clinic with sudden loss of vision. Her clinical and ophthalmologic examinations and laboratory tests were carried out and the results were evaluated. Results The patient's history revealed a diagnosis of AIDS established 5 years ago. Her corrected visual acuity was limited to light perception in the right eye and 20/60 in the left eye. There was afferent pupillary defect in the right eye. Posterior segment examination demonstrated central retinal artery occlusion in the right eye and cotton-wool spots in the left eye. The clinical examination and laboratory test results did not reveal any comorbid disease state that can contribute to this presentation. Conclusions As thrombi may develop in patients with human immunodeficiency virus infection, they should be closely followed up for the development of vasoocclusive disease.

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.

Central retinal artery occlusion (CRAO) is a blinding event but not considered as a common emergency problem. Since awareness of the case is low, patients usually come to the ophthalmologist later than the golden period and havingthe worst prognosis. We report the case of patient with a central retinal artery occlusion that had visual improvement after emergency treatment.A 47-year-old woman with no comorbidities presented with symptoms of a sudden blurred vision, no pain or redness in the right eye (RE). Best-corrected visual acuity in the RE was 1/60. A relative afferent pupillary defect was observed in the RE. Ocular fundus examination of RE was suggestive of CRAO. Emergency treatment were performed, including rebreathing of expired CO2, ocular massage and ocular chamber paracentesis. One week later, the visual acuity was improved.This case highlights that fast and accurate response in acute management of CRAO should be conducted, especially within the golden hours which is less than 6 hours after the accident, to prevent permanent visual loss of thepatient.

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.
