Purpose: To assess the value of increased perifoveal retinal vascular tortuosity in optical coherence tomography angiography (OCTA) images as a biomarker of early hypertensive retinopathy and compare its clinical sensitivity and accuracy with traditional morphological changes used for Scheie classification.
Methods: OCTA images of 81 eyes (40 eyes from 20 hypertensive subjects and 41 eyes from 21 control subjects) were obtained retrospectively. Hypertensive retinopathy changes in randomized eyes were graded according to the Scheie classification, and perifoveal vessels were traced in a masked fashion.
Visual acuity (VA) is a traditional measure of central visual function, particularly the ability of the eye to perceive details. In a clinical setting, standardized charts are commonly used to quickly assess VA. Namely, the Early Treatment of Diabetic Retinopathy Study (ETDRS) VA test chart is the gold standard for VA testing in the clinical setting.

- The study aimed to analyze the first 1000 patients with confirmed COVID-19 at a NYC medical center, focusing on their clinical journey through various care settings.
- Patient data showed the main symptoms were cough, fever, and dyspnea, with a significant number having pre-existing conditions like hypertension and diabetes.
- Results indicated high ICU admission rates, long hospital stays, and notable mortality, with a distinct pattern in the timing of intubation based on symptom onset.
Article Synopsis
- The study aimed to analyze the characteristics and clinical experiences of COVID-19 patients in a New York City hospital during early March to early April 2020.
- Researchers reviewed medical records of the first 1000 patients with confirmed SARS-CoV-2 infections, focusing on their demographics, symptoms, comorbidities, hospital courses, and outcomes.
- Findings revealed that cough, fever, and dyspnea were the most common symptoms, with many patients having pre-existing health issues; those in ICUs were mostly older males with long hospital stays, and a significant proportion developed serious complications like acute kidney injury.
