Primary cardiac valve tumours are rare. This is a case report of a 32-year-old non-smoker man with a history of stroke 1 year prior and no other cardiovascular risk factors. The patient was admitted to our acute stroke ward for recurrent left hemiparesis, slurring of speech, facial asymmetry and central retinal artery occlusion. Initial laboratory investigations and ECG were normal. An urgent CT brain showed a large hypodense area at the right frontal, parietal, temporal, occipital region with effaced sulci and right lateral ventricle with midline shift and cerebral oedema in keeping with acute infarction. We proceeded with CT angiography of the cerebral and carotid on the following day, which revealed no evidence of thrombosis, aneurysm or arteriovenous malformation. There were no abnormal beaded vessels to suggest vasculitis. Transthoracic echocardiography revealed a large mobile mass in the left atrium. Meanwhile, MRI cardiac confirmed a large ill-defined mobile solid mass attached to the mitral valve's inferoseptal component suggestive of mitral valve myxoma. This case report highlights the significance of considering a cardiogenic source of emboli in patients with large cerebral infarcts and other cardiac embolic phenomena. Imaging modalities such as echocardiography and cardiac MRI will help detect treatable conditions, such as valvular myxoma and prevent further complications.

Rhino-orbital-cerebral mucormycosis (ROCM) is an uncommon but fatal fungal infection. We report a rare case of unilateral ROCM with ipsilateral central retinal artery occlusion and contralateral choroiditis, which later progressed to endogenous fungal endophthalmitis. The patient was successfully treated with sinuses debridement, systemic liposomal amphotericin B, and intravitreal amphotericin B. The endophthalmitis completely resolved with good vision, but the ROCM eye remained blind due to central retinal artery occlusion.

Central retinal arterial occlusion is an ocular emergency. Central retinal artery occlusion following cardiac procedures have been described in adults. We describe a pediatric patient who developed central retinal artery occlusion following pulmonary artery stenting. It is important to highlight this potential risk to ensure early diagnosis and prompt treatment.

Fulltext Herpes Zoster Ophthalmicus, Central Retinal Artery Occlusion, and Neovascular Glaucoma in an Immunocompetent Individual

Ahmad SS, Suan ALL, Alexander SM

J Ophthalmic Vis Res, 2019 3 2;14(1):97-100.

PMID: 30820294 DOI: 10.4103/jovr.jovr_65_17

Purpose: To report the unusual case of an immunocompetent individual with herpes zoster ophthalmicus who developed central retinal artery occlusion and subsequent neovascular glaucoma.

Case Report: A 40-year-old, immunocompetent patient was diagnosed with herpes zoster ophthalmicus and central retinal artery occlusion on initial presentation. Subsequently, he developed neovascular glaucoma.

Conclusion: There are a few case reports of central retinal artery occlusion developing after varicella zoster virus infection. However, a literature search found no reports of neovascular glaucoma following central retinal artery occlusion secondary to varicella zoster virus infection. The present case report indicates that neovascular glaucoma is a possible complication in such a scenario.

Fulltext Unilateral visual loss after spine surgery in the prone position for extradural haematoma in a healthy young man

This case reports a patient who developed central retinal artery occlusion following spinal surgery in the prone position. When placed in this position, especially as a result of malposition of the head, the patient may develop external compression of the eye which leads to central retinal artery occlusion. Therefore, a special precaution must be given for adequate eye protection during prolonged prone-positioned spine surgery.

Fulltext Central retinal artery occlusion and ophthalmoplegia following spinal surgery in the prone position

PMID: 20954560 MyJurnal

A 14 year old boy underwent a 7 hour long spinal surgery for scoliosis in the prone position. In the immediate postoperative period, he developed right proptosis, periorbital swelling, chemosis and total ophthalmoplegia. The vision in his right eye was only counting fingers and the intraocular pressure was 68 mmHg. Fundus examination revealed occlusion of the right central retinal artery. A rare manifestation of both vein and artery occlusion was possible in this patient as a result of external ocular compression due to a prolonged period in the prone position. This report highlights the importance of being aware of the possible complications of external ocular compression in non-ocular surgery.

Systemic lupus erythematosus (SLE) is a chronic, multisystem, autoimmune disease that can affect any part of the human body including the eyes. Common blinding ocular manifestations include central retinal artery occlusion (CRAO), central retinal vein occlusion (CRVO), severe vaso-occlusive retinopathy, and optic nerve involvement. Antiphospholipid syndrome (APS) in lupus is usually associated with large vessel occlusions and needs prompt treatment with anticoagulant. We are reporting two cases of APS in SLE patients that presented with CRVO (case 1) and vaso-occlusive lupus retinopathy (case 2). Both cases were positive for antiphospholipid antibody (APA) and were treated with immunosuppression, anticoagulant, and laser treatment. Thus, screening for APA is vital in SLE patients with lupus retinopathy, as prompt treatment with anticoagulants is important to prevent further vascular thrombosis, which worsens the visual prognosis.
