Introduction: The Newborn Acuity Cards (NAC) have been used on neonates and were noted to be simple, fast, and reliable. The distinguishing features of NAC include central placement of the gratings and wide range of grating acuity that can be measured. In the current study, NAC were used with children who had developmental delays to determine the…

The limitation of conventional visual acuity assessment, which primarily focuses on individual eye performance (monocular visual acuity tests). This study addresses this limitation by emphasizing the importance of binocular vision, where both eyes work together. Binocular vision provides numerous advantages, such as improved depth perception, a…

One of the world's most famous pyramids is not located in Egypt but is on a music album cover by the band Pink Floyd. However, not a pyramid but a prism, the iconic image of a beam of light turning into a rainbow is a powerful symbol that captures the complexities of colour perception across cultures and individuals. This study examines how…

Haptic perception is used in the anatomy laboratory with the handling of three-dimensional (3D) prosections, dissections, and synthetic models of anatomical structures. Vision-based spatial ability has been found to correlate with performance on tests of 3D anatomy knowledge in previous studies. The objective was to explore whether haptic-based…

Introduction: This study aims to assess the prevalence of visual impairment and refractive error among learners who are deaf or hard of hearing in schools for Deaf students in Ghana. Methods: A descriptive cross-sectional study design was used to assess the distance visual acuity with the logMAR "E" chart, and ocular health was assessed…

The burden of childhood visual impairment and disparities in access to pediatric vision care remain pressing issues in the United States. School-based vision programs (SBVPs) serve as one approach to advancing health equity. Operating at the intersection of schools and healthcare, SBVPs can increase access to pediatric vision services, improve…

Background: School-based health centers (SBHCs) have been shown to offer substantial benefits to students but we know little about how the public thinks about them. We sought to assess US public attitudes about SBHCs and the provision of 7 health service lines--primary care, preventive care, vaccinations, preventive dental care, preventive vision…
