Current Guidelines on Management of Amaurosis Fugax and Transient Ischemic Attacks
Asia Pac J Ophthalmol (Phila). 2022 Feb 24. doi: 10.1097/APO.0000000000000511. Online ahead of print.ABSTRACTTransient ischemic attack (TIA) is defined as a transient episode of neurological dysfunction resulting from focal brain, spinal cord, or retinal ischemia, without associated infarction. Consequently, a TIA encompasses amaurosis fugax (AF) that is a term used to denote momentary visual loss from transient retinal ischemia. In this review, we use the word TIA to refer to both cerebral TIAs (occurring in the brain) and AF (occurring in the retina). We summarize the key components of a comprehensive evaluation and mana...

Response to the Letter to the Editor by Kishore et al.
We appreciate these comments on our recently published article on the referral pattern of patients with acute retinal arterial ischemia at our institution.1 As Dr. Kishore et al. know, we have been trying for quite some time now to educate eye care providers regarding the need to have these patients immediately evaluated in emergency facilities with the help of neurologists with an expertise in stroke. Over the past decade, we alerted the ophthalmology community to the necessity of following previously published guidelines by the American Heart Association and the American Stroke Association.

Development of cognition decline in non-acute symptomatic patients with cerebral small vessel disease: Non-Acute Symptomatic Cerebral Ischemia Registration study (NASCIR)--rationale and protocol for a prospective multicentre observational study
This study aims to investigate risk factors, clinical course, cerebral and retinal imaging changes, proteomics features of non-symptomatic ischaemia symptomatic patients with cognitive decline. Methods and analysis The Non-Acute Symptomatic Cerebral Ischemia Registration study is a multicentre, registry-based, prospective observational study, is designed to investigate the cognitive decline in non-acute ischaemia symptomatic patients. We will recruit 500 non-acute ischaemia symptomatic patients from four tertiary hospitals in China. For this study, non-acute ischaemia symptoms will be defined as headaches, dizziness and m...

Causal associations between circulating adipokines and cardiovascular disease: A Mendelian randomization study
CONCLUSIONS: Our findings reveal the causal association between resistin and AF, probably acting through blood pressure, and suggest potential causal associations between chemerin and CAD, RBP4 and HF.PMID:35134201 | DOI:10.1210/clinem/dgac048

Mild Hypertensive Retinopathy and Risk of Cardiovascular Disease: The Suita Study
CONCLUSION: Mild hypertensive retinopathy was positively associated with CVD and stroke risk in the urban Japanese population. Especially, generalized arteriolar narrowing and enhanced arteriolar wall reflex were positively associated with CVD risk. These findings suggested that retinal photography could be helpful for cardiovascular risk stratification in the primary cardiovascular prevention.PMID:35034920 | DOI:10.5551/jat.63317

Vascular Reactivity to Hypercapnia Is Impaired in the Cerebral and Retinal Vasculature in the Acute Phase After Experimental Subarachnoid Hemorrhage
Conclusion: This study provides a detailed temporal analysis of impaired cerebral vascular CO2 reactivity starting immediately after SAH and lasting up to 6 h. Importantly, the retinal vessels participate in these acute changes underscoring the promising role of the retina as a potential non-invasive screening tool after SAH. Further studies will be required to determine the correlation with functional outcomes.

Detection and Grading of Hypertensive Retinopathy Using Vessels Tortuosity and Arteriovenous Ratio
AbstractHypertensive retinopathy (HR) refers to changes in the morphological diameter of the retinal vessels due to persistent high blood pressure. Early detection of such changes helps in preventing blindness or even death due to stroke. These changes can be quantified by computing the arteriovenous ratio and the tortuosity severity in the retinal vasculature. This paper presents a decision support system for detecting and grading HR using morphometric analysis of retinal vasculature, particularly measuring the arteriovenous ratio (AVR) and retinal vessel tortuosity. In the first step, the retinal blood vessels are segmen...

Incorporation of Retinal Arteriolosclerosis into Risk Stratification of Blood Pressure Category According to the 2017 ACC/AHA Blood Pressure Guideline
CONCLUSION: Incorporation of the assessment for RA may facilitate the CVD risk stratification of people classified based on the 2017 ACC/AHA BP guideline, particularly for those categorized in stage 1 hypertension.PMID:34866070 | DOI:10.5551/jat.63262
