Introduction: The performance of "en face" optical coherence tomography (OCT) in screening for chloroquine (CQ) or hydroxychloroquine (HCQ) retinopathy has not been largely explored. The aim of this study was to determine the concordance of "en face" OCT with multifocal electroretinography (mfERG) in screening for CQ/HCQ retinopathy.
Methods: This is a prospective cohort study conducted at the Rothschild Foundation Hospital, Paris, between August 2016 and February 2021. Patients taking HCQ were followed up over 2 consecutive years and received an "en face" OCT and a mfERG on each visit.
Results: A total of 91 patients (182 eyes) were analyzed. mfERG and "en face" OCT were concordant in 147 eyes (86.3%). Cohen's kappa coefficient for concordance between mfERG and "en face" OCT was considered weak with a value 0.61 (95% CI: 0.50-0.72). The sensitivity and specificity of "en face" OCT were 70% (95% CI: 59-79%) and 91% (95% CI: 83-96%), respectively, relatively to mfERG. Proportion of abnormal R2/R5 and R3/R5 ratios did not differ between patients with normal and abnormal "en face" OCT (p = 0.2).
Discussion: "En face" OCT and mfERG have low concordance and cannot be used interchangeably as each investigation evaluates a different facet of CQ/HCQ retinopathy. "En face" OCT could be used as a complement in screening for CQ/HCQ retinal toxicity if the anomalies detected on "en face" OCT are confirmed by B-scan OCT sections.

Precis: Artificial intelligence applied to OCTA images demonstrated high accuracy in estimating 24-2 visual field maps by leveraging information from pararpapillary area.
Purpose: To develop deep learning (DL) models estimating 24-2 visual field (VF) maps from optical coherence tomography angiography (OCTA) optic nerve head (ONH) en face images.
Methods: A total of 3148 VF OCTA pairs were collected from 994 participants (1684 eyes).

Purpose: To characterize the cavity hyperreflective-content and septum's motion artifact (CHASMA) in en face optical coherence tomography angiography (OCTA) across multiple ocular fundus abnormalities.
Methods: This was a cross-sectional, observational study. Subjects with extravascular OCTA signals arising from the cavity's hyperreflective-content and/or septum were enrolled.

Background Atherosclerosis involves inflammatory and thrombotic mechanisms, to which platelets, CD4+ T effector cells, and transforming growth factor β (TGFβ) all contribute importantly. Platelets are the principal source of circulating TGFβ, which profoundly regulates CD4+ T effector cell responses. The impact of platelet-derived TGFβ on atherosclerosis is, however, unknown.

To test the effects of extra virgin olive oil (EVOO) enriched in specific bioactive compounds (EVOO HBC) on atherosclerosis and fatty liver, three isocaloric Western diets differing in the type of fat (palm, EVOO, or EVOO HBC) were fed to Apoe-deficient mice for 12 weeks. Plasma lipids, lipoprotein characterization, circulating CD36-expressing monocytes, and M2 peritoneal macrophages were quantified. Hepatic squalene and cross-sectional and en face atherosclerotic lesions were analyzed.
