Purpose: The present study aimed to review the effect of dehydration during Ramadan fasting on the health and ocular parameters leading to changes in eye function. Methods: Articles included in the study were taken from Pub Med, Ovid, Web of Science and Google Scholar up to 2014.Related articles were also obtained from scientific journals in fasting and eye. Results: Dehydration and nutrition c...

This paper presents the first photoplethysmographic (PPG) signal dynamic-based biometric authentication system with a Siamese convolutional neural network (CNN). Our method extracts PPG signal’s characteristics from its diffusive dynamics, characterized by geometric patterns in (p,q)-planes specific to 0–1 test. dynamics are strongly dependent on vascular bed’s biostructure, unique each individ...

Background: Cataract refractive errors are caused by cataracts. It can go up to several dioptres (D). Correction of expected during cataract surgery altering the axial length measurement. Determine effect posterior sub-capsular cataracts on eye's status. Methods: 112 patients with participated in study. The most common error found PSC was astigmatism, followed myopia. study conducted at Angel E...

PURPOSE To explore 3-year change in spherical refractive error and ocular components among white Northern Irish schoolchildren. METHODS Baseline data were collected among 6- to 7-year-old and 12- to 13-year-old children. Three years after baseline, follow-up data were collected. Cycloplegic refractive error and ocular components measurements (axial length [AL], anterior chamber depth [ACD], c...
