Central retinal artery occlusion (CRAO) is an event most often caused by an embolus originating in the ipsilateral carotid artery, aortic arch, or heart. CRAO may result from partial or complete occlusion of the central retinal artery (CRA), which acts as the primary blood supply to the inner neurosensory retina, and typically results in profound vision loss and permanent visual disability. No consensus has emerged regarding the optimal treatment of CRAO. All proposed treatments are of questionable efficacy and many have uncertain risk profiles...

Acute retinal arterial ischemia, including vascular transient monocular vision loss (TMVL) and branch (BRAO) and central retinal arterial occlusions (CRAO), are ocular and systemic emergencies requiring immediate diagnosis and treatment. Guidelines recommend the combination of urgent brain magnetic resonance imaging with diffusion-weighted imaging, vascular imaging, and clinical assessment to identify TMVL, BRAO, and CRAO patients at highest risk for recurrent stroke, facilitating early preventive treatments to reduce the risk of subsequent stroke and cardiovascular events...

BACKGROUND: The critical time from onset of complete occlusion of the central retinal artery (CRA) to functionally significant inner retinal infarction represents a window of opportunity for treatment and also has medical-legal implications, particularly when central retinal artery occlusion (CRAO) complicates therapeutic interventions. Here, we review the evidence for time to infarction from complete CRAO and discuss the implications of our findings. METHODS: A Medline search was performed using each of the terms "central retinal artery occlusion", "retinal infarction", "retinal ischemia", and "cherry red spot" from 1970 to the present including articles in French and German...

Optical coherence tomography angiography (OCTA) is a new, noninvasive technology that enables detailed evaluation of flow in the retinal and choroidal vasculature. The authors believe this to be the first report to describe the optical coherence tomography angiography findings associated with combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO).

Objective: This case report presents a patient with central retinal artery occlusion (CRAO) who was successfully treated with hyperbaric oxygen (HBO₂) but subsequently suffered a recurrence of his visual loss. Methods: CRAO may be treated successfully with HBO₂ if treatment is undertaken promptly after the onset of vision loss. The goal of HBO₂ therapy is to oxygenate the ischemic inner retinal layers via diffusion from the hyperoxygenated choroidal circulation until recanalization of the central retinal artery occurs...

A 25-year-old male patient presented to the emergency department with the chief complaint of sudden blindness and was found to have suffered bilateral central retinal artery occlusion (CRAO). This process is most commonly the result of a thrombus or embolus that occludes the retinal artery, and normally presents in a single eye in patients older than 65 who are predisposed to vascular disease. Diagnosis relies most heavily upon funduscopic exam. Potential treatments involve ocular massage, acetazolamide, anterior chamber paracentesis and systemic or local fibrinolysis...

Background and purpose: Acute central retinal artery occlusion (CRAO) is a serious ophthalmologic emergency that may result in monocular blindness. To date, studies evaluating intra-arterial thrombolysis (IAT) have not shown a definitive clinical benefit. We have conducted a systematic review with a meta-analysis to effectively evaluate this treatment option. Methods: A systematic literature search was focused on studies containing five or more patients undergoing IAT that included a control group treated with standard therapy...

Purpose: To describe a patient with acute central retinal artery occlusion (CRAO) during vitrectomy surgery and the possible role of vitrectomy in acute CRAO management. Observations: An 84-year-old man presented with broad vitreomacular traction and epiretinal membrane in the right eye. Preoperative assessment clearly showed normal retinal vasculature. On starting vitrectomy, complete CRAO with marked segmentation of all retinal vessels was noted. Vitrectomy was performed in the usual manner and once the posterior hyaloid detached from the disc, immediate complete revascularization of the retinal vessels was noted...

Cosmetic facial filler-related central retinal artery occlusion (CRAO) is a devastating complication of facial hyaluronic acid (HA) injection and can be managed by intra-arterial thrombolytic therapy (IATT). The authors report on a 20-year-old woman who developed unilateral CRAO due to facial HA injection and who, despite prompt IATT, lost vision. A review of the related literature found 14 other female patients who developed cosmetic facial filler-related CRAO and accepted IATT management. In no case was vision loss clinically improved...

Central retinal artery occlusion (CRAO) is a severe disease, often causing blindness. We evaluated the efficacy and safety of a surgical procedure for the treatment of acute CRAO in which retinal arterial cannulation with tissue plasminogen activator (tPA) is performed. The surgical procedure consisted of vitrectomy followed by cannulation of the central retinal artery and injection of tPA (200 μg) using a 47-gauge microneedle. Thirteen CRAO patients were treated within 48 hours of the onset of symptoms...

BACKGROUND: Central retinal artery occlusion (CRAO) is an ophthalmological emergency, the retinal analog of a stroke. To date there is no consensus or national guidelines on how this disorder should be managed. As academic neurologists and ophthalmologists treat CRAO frequently, we set out to understand how these clinicians approach patients with CRAO with a national survey. METHODS: We identified university-associated teaching hospitals offering vascular neurology, neuro-ophthalmology and/or retina fellowships in the US and asked the directors of the programs to respond to questions in an open response format to profile the acute management of CRAO at their institution...

BACKGROUND: Perioperative visual loss after spinal surgery is a devastating complication for the patient and the surgical team. Two known major causes are ischemic optic neuropathy and central retinal artery occlusion (CRAO). Traditional understanding of CRAO has been consistently related to occurrence of periocular trauma and signs of increased intraorbital pressure in addition to visual loss. However, such orbital signs are not a feature of any common perioperative visual loss syndrome...

A 15-year-old healthy boy developed acute, rapidly progressing visual loss in left eye following herpes zoster dermatitis, with a combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO), along with optic perineuritis. Laboratory tests were negative. Despite an empirical, intensive antiviral treatment with systemic corticosteroids, and vision could not be restored in the affected eye. Herpes zoster dermatitis, in an immunocompetent individual, may be associated with a combined CRAO and CRVO along with optic perineuritis, leading to profound visual loss...

BACKGROUND: Leukemic infiltration of the optic nerve is relatively rare. While previously described in acute leukemia, the infiltration in our case represents central nervous system (CNS) metastasis of Burkitt-type lymphoma that developed as a complication of solid-organ transplantation, resulting in a bilateral infiltrative optic neuropathy with sequential, bilateral central retinal artery occlusion (CRAO) and devastating vision loss. METHODS: The medical record, serial ophthalmic examination findings, clinical course, and imaging including magnetic resonance imaging (MRI), fundus photographs, and fluorescein angiography of a single patient were retrospectively reviewed...
