BACKGROUND: Visual acuity (VA) only slightly explains variability in reading performance, whereas other visual and non-visual parameters have been reported to influence reading performance; however, in ophthalmologic and optometric clinical practice and research, where standardised reading tests are used, many of these parameters are often neglected. The purpose of this study was to give insight into how various visual and non-visual parameters are associated with reading performance in normally sighted subjects...

BACKGROUND: Cataract, a leading cause of vision impairment, is due to the lens becoming excessively optically dense. Change in the lens optical density (LOD) could be a useful indicator of incipient nuclear cataract and would necessitate the development of accurate measurement techniques. Mapcat sf™ is a heterochromatic flicker photometer for measuring macular pigment optical density (MPOD) under photopic conditions. In the process, it also measures LOD that is needed in the calculation of MPOD...

Charles Bonnet Syndrome is a condition where visual hallucinations occur as a result of damage along the visual pathway. Patients with Charles Bonnet Syndrome maintain partial or full insight that the hallucinations are not real, absence of psychological conditions, and absence of hallucinations affecting other sensory modalities, while maintaining intact intellectual functioning. Charles Bonnet Syndrome has been well documented in neurologic, geriatric medicine, and psychiatric literature, but there is lack of information in optometric and ophthalmologic literature...

Gait analysis is commonly used to identify gait changes and fall risk in clinical populations and seniors. Body-worn inertial sensor based gait analyses provide a feasible alternative to optometric and pressure based measurements of spatiotemporal gait characteristics. We assessed validity and relative and absolute reliability of a body-worn inertial sensor system (RehaGait(®)) for measuring spatiotemporal gait characteristics compared to a standard stationary treadmill (Zebris(®)). Spatiotemporal gait parameters (walking speed, stride length, cadence and stride time) were collected for 24 healthy seniors (age: 75...

PURPOSE: To investigate the potential of a mobile ophthalmic unit in the schoolyard to improve the follow-up rate for children who have failed an optometric in-school screening program. Previously, the optometric program made referrals to the center and only 53% of students attended the desired ophthalmology consultation. METHODS: This was a cohort study of students conducted in elementary school lots in socioeconomically disadvantaged communities. The mobile ophthalmic unit visited schools where students with parental consent who needed examination had been identified by an in-school optometric vision care program...

BACKGROUND: Clinical reasoning is central to any health profession but its development among learners is difficult to assess. Over the last few decades, the script concordance test (SCT) has been developed to solve this dilemma and has been used in many health professions; however, no study has been published on the use of the script concordance test in optometry. The purpose of this study was to develop and validate a script concordance test for the field of optometry. METHODS: A 101-question script concordance test (27 short clinical scenarios) was developed and administered online to a convenience sample of 23 second-year and 19 fourth-year students of optometry...

PURPOSE: To determine if routine eye examinations in asymptomatic patients result in spectacle prescription change, new critical diagnosis, or new management of existing conditions. We also investigate whether age and time between assessments (assessment interval) impact detection rates. METHODS: The Waterloo Eye Study (WatES) database was created from a retrospective file review of 6397 patients seen at the University of Waterloo Optometry Clinic. Significant changes since the previous assessment (significant change) were defined as a change in spectacle prescription, presence of a new critical diagnosis, or a new management...

Binocular vision is the most important visual cue for spatial orientation in many sports. In this study, we investigated how binocular vision was influenced by an eye training program that may be used to improve individual's oculomotor function. The experiment involved twenty-four female student athletes from team ball sports (soccer, basketball, handball). After an initial testing session, 12 participants were randomly allocated to the experimental group. Optometric investigation which included synoptophore testing and a test of dissociated horizontal phoria based on the Maddox method was performed three times: before the experiment, after eight weeks of eye training (3 times a week for 20 minutes), and four weeks after the experiment was terminated...

This study evaluated self-perceived vision difficulty in individuals with a history of farming, forestry, and fishing (FFF) occupations. Data from the 2005-2006 and 2007-2008 NHANES questionnaires were used for this analysis. A self-perceived vision difficulty indicator was derived from responses to three separate measures. Those indicating farming, forestry, or fishing as longest job worked were classified as having an FFF history and compared to those reporting any other occupation. Logistic regression analyses utilizing NHANES sampling weights were conducted...
