AIM To determine the best method of estimating the optimum magnification needed by visually impaired patients. METHODS The magnification of low vision aids prescribed to 187 presbyopic visually impaired patients for reading newspapers or books was compared with logMAR distance and near acuity (at 25 cm) and magnification predicted by +4 D step near additions. RESULTS Distance letter (r = 0....

Introduction: Nailfold capillaroscopy is a simple, non-invasive technique used to assess microcirculation in various diseases such as Systemic Sclerosis, Dermatomyositis, Diabetes Mellitus, and Hypertension etc. Microcirculation is the part of the circulation where oxygen, nutrients, hormones, and waste products are exchanged between circulating blood and parenchyma cells through the blood vess...

Background Patients with low vision typically have reduced visual acuity and a significant loss of contrast sensitivity, often in combination with visual field loss. These impairments cause a number of disabilities including diYculty with reading, writing, recognising faces, watching television, orientation and mobility, and completing activities of daily living. In a recent large scale survey ...

This work explores the use of infrared low-cost cameras for monitoring peripheral oxygen saturation (SpO2), a vital sign that is particularly important individuals with fragile health, such as elderly. The development contactless SpO2 utilizing RGB has already proven successful. study utilizes Eulerian Video Magnification (EVM) technique to enhance minor variations in skin pixel intensity parti...

OBJECTIVES The aim of this hospital-based prospective study was to evaluate the diagnostic ability of breast cancer screening in Korean middle-aged women using age, ultrasonography, mammography, and magnification mammography, which are commonly used in most hospitals. METHODS A total of 21 patents were examined using ultrasonography, mammography, and magnification mammography, and their data ...
