REVIEW
Michael Dattilo, Valérie Biousse, Nancy J Newman
Central retinal artery occlusion (CRAO) is caused by partial or complete occlusion of the central retinal artery, most commonly by an embolus from the ipsilateral carotid artery, aortic arch, or heart, and is the ocular equivalent of an acute cerebral ischemic event. The risk factors for a CRAO and acute cerebral ischemia are very similar, if not identical. Because no current therapeutic intervention has been shown to improve visual outcomes compared with the natural history of CRAO, management of CRAO should be focused on secondary prevention of vascular events, such as cerebral ischemia, myocardial infarction, and cardiovascular death...

Central retinal artery occlusion (CRAO) is a devastating ocular emergency characterized by acute painless visual loss in the ipsilateral eye. We describe the case of acute non-arteritic CRAO associated fusiform internal carotid-ophthalmic artery aneurysm with intraluminal thrombus. Despite the rarity of this condition, we suggest that carotid-ophthalmic artery aneurysm should be included in the differential diagnosis of CRAO.

BACKGROUND: Intra-arterial thrombolysis (IAT) for the treatment of acute central retinal artery occlusion (CRAO) has demonstrated variable results for improving visual acuity and remains controversial. Despite limited evidence, time from symptom onset to thrombolysis is believed to be an important factor in predicting visual improvement after IAT. METHODS: A comprehensive review of the literature was conducted and individual subject level data were extracted from relevant studies...

Central retinal artery occlusion (CRAO) is an infarction to the retina that results in acute, frequently severe vision loss. Long-term complications such as ocular neovascularization (ONV) can occur and result in neovascular glaucoma and vitreous hemorrhage. Recent studies have explored acute hyperbaric oxygen (HBO) therapy as a promising treatment for CRAO to improve long-term vision potential; however, its effects on CRAO complications have not been well characterized. This study was conducted to better characterize the effects of HBO therapy on complications from CRAO...

Several studies investigating the role of retinal vascular occlusions, on cerebrovascular diseases (CVD) have been reported, but the results are still inconsistent. We therefore sought to evaluate the relationship between retinal vascular occlusions and CVD.We systematically searched the Cochrane Library, PubMed, and ScienceDirect databases through January 31, 2016 for studies evaluating the effect of retinal vascular occlusions on the risk of CVD. Data were abstracted using predefined criteria, and then pooled by RevMan 5...

Nancy E Epstein
BACKGROUND: In a prior article, "Perioperative visual loss (POVL) following prone spinal surgery: A review," Epstein documented that postoperative visual loss (POVL) occurs in from 0.013% to 0.2% of spine procedures performed in the prone position. POVL is largely attributed to ischemic optic neuropathy (ION), central retinal artery occlusion (CRAO), cortical blindness (CB), direct compression (prone pillows/horseshoe, eye protectors), and rarely, acute angle closure glaucoma. METHODS: Risk factors for ION include prolonged surgery, extensive fusions, anemia, hypotension, hypovolemia, diabetes, obesity, use of the Wilson frame, male sex, and microvascular pathology...

The authors report the use of optical coherence tomography angiography (OCTA) to determine retinal blood flow in a patient with central retinal artery occlusion (CRAO). Spectral-domain OCTA (SD-OCTA) was performed on an eye with CRAO. En face vascular images were constructed using an optical microangiography algorithm. The retinal vasculature was clearly imaged with high fidelity; areas of perfused retina were identified with exquisite detail. This study supports use of OCTA in diagnosing and monitoring CRAOs...

José Alberto Lemos, Carla Teixeira, Rui Carvalho, Tiago Fernandes
BACKGROUND: Combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) is an uncommon retinal vascular disease which causes sudden visual acuity loss and is associated with poor prognosis and the development of severe complications. We report a very rare case of combined CRAO and CRVO in a patient with factor V Leiden (FVL) mutation (only 3 cases published). To our knowledge, this is the first case of combined CRAO and CRVO treated with hyperbaric oxygen therapy (HBOT)...

BACKGROUND: Ocular emergencies account for 2-3% of all emergency department (ED) visits. Sonographic evaluation of the eye offers a very useful diagnostic tool in the ED. In the ED setting, ocular ultrasound could identify a retinal detachment, or a massive vitreous hemorrhage, and the training for emergency medicine practitioners is quite easy. CASE REPORT: An 84-year-old woman presented to our ED with a painless acute vision loss in her right eye. Immediate bedside emergency ocular ultrasound was performed, and it showed a retrobulbar hyperechoic material, suggestive of an embolus within the central retinal artery...
