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…

The goal of this study is to assess the referral rate accuracy of photoscreening versus the chart methodology in identifying preschool children at risk of amblyopia and amblyogenic refractive error. Vision screenings using the plusoptiX S12 and the LEA chart were performed on 127 children, aged 3-5 years old. Comprehensive eye exams were performed…

Introduction: Within the field of visual impairment, there is no set of standards that guide teachers of students with visual impairments as they conduct, report, and share functional vision assessment (FVA) results with other educational team members, and university instructors vary in how they teach the assessment process to preservice teachers.…

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…

Introduction: This study analyzed 39 data collection tools used by teachers of students with visual impairments when completing functional vision assessments (FVAs). Methods: In 2017, teachers of students with visual impairments submitted data collection tools used in the FVA process. These tools were then compared with the 23 FVA components…

Children in low-income communities are at risk for developmental delays and sensory losses. mHealth screening tools enable community health workers to detect developmental delays and sensory losses. This study aims to describe a combined (developmental and sensory -- hearing and vision) mHealth-supported screening programme conducted by community…

This study aimed to develop a valid and reliable instrument that measures the functional vision of students with low vision. Thus, an assessment tool and performance activities were developed for three vision skill groups (near vision skills, distance vision skills, and visual field) that include functional vision skills. The universe was 1485…

Introduction: This study analyzed survey responses from 314 teachers of students with visual impairments regarding the tools and procedures used in completing functional vision assessments (FVAs). Methods: Teachers of students with visual impairments in the United States and Canada completed an online survey during spring 2016. Results: The…

Introduction: Globally, more than 50 million children have hearing or vision loss. Most of these sensory losses are identified late due to a lack of systematic screening, making treatment and rehabilitation less effective. Mobile health (mHealth), which is the use of smartphones or wireless devices in health care, can improve access to screening…

Vision plays a key role in a child's development. Early detection and treatment of vision abnormalities decreases future complications. Follow-up vision care is a common problem. Barriers to vision care include financial cost, lack of insurance knowledge to cover costs, and disbelief of vision results. The purpose of this evidence-based pilot…

The Houston Independent School District (HISD)'s campus-based vision screening program is designed to identify students who experience vision impairments, communicate the potential needs to students along with their parents/guardians, and provide service alternatives for students to receive vision care, including services that are offered free of…

Purpose: The purposes of this study were to (a) investigate the effect of physical effort (cycling for 60 min at 60 ± 5% of individually computed reserve heart-rate capacity), combined with 2 different levels of cognitive demand (2-back, oddball), on intraocular pressure (IOP) and subjective judgments of perceived exertion (ratings of perceived…

More than 20 percent of all school-aged children in the United States have vision problems, and low-income and minority children are disproportionately likely to have unmet vision care needs. Vision screening is common in U.S. schools, but it remains an open question whether screening alone is sufficient to improve student outcomes. We implemented…

Vision screenings are intended to efficiently identify students with possible visual impairment and initiate a referral for diagnosis and treatment. In many cases, at-risk students do not access the recommended care or experience delays in receiving care. The purpose of this article is to report the effect on adherence to vision screening…

During the 2016-2017 school year, the Vision Partnership program provided vision services to approximately 3,353 students enrolled in the Houston Independent School District. This evaluation brief describes HISD students' participation in campus-based screenings and the Vision Partnership, and the academic achievement of students served by the…
