INTRODUCTION The Randot Preschool Stereoacuity Test is a widely used three-book test for the assessment of binocular status. Using a prototype, we previously reported high testability in children as young as 3 years, validity data, and some normative data. Here we report extensive normative and validity data for the final version of the test. In addition,(More)
PURPOSE To establish a normative database of peripapillary retinal nerve fiber layer (RNFL) thickness, macular thickness, and retinal layer thickness in healthy North American children, using spectral-domain optical coherence tomography (SD OCT). DESIGN Prospective cross-sectional study. METHODS This institutional study enrolled 83 healthy children(More)
INTRODUCTION We examined the critical period for deprivation amblyopia in a cohort of patients with dense bilateral congenital cataracts to investigate the optimum timing for surgical treatment. METHODS Thirty-seven infants with dense bilateral congenital cataracts that were extracted by 31 weeks of age were enrolled prospectively. Visual acuity outcome(More)
PURPOSE Intraocular lenses (IOLs) are now being implanted in infants and children with unilateral cataracts. However, there are no prospective data on the development of visual acuity after implantation. The aim of the present study was to prospectively assess the development of acuity in infants and preschool children who received IOLs or aphakic contacts(More)
PURPOSE To provide normative pediatric visual acuity data using HOTV optotypes presented on the Electronic Visual Acuity Tester following the Amblyopia Treatment Study (ATS) protocol. METHODS Monocular testing was conducted on 384 healthy full-term children ranging from 3 to 10 years of age (mean, 5.4 years; SD, 1.8 years). A total of 373 children(More)
PURPOSE The Children's Visual Function Questionnaire (CVFQ) is a vision-specific quality-of-life instrument designed for use with children up to 7 years of age. The goal of this study was to assess the construct validity of CVFQ subscales by examining their sensitivity to four research questions commonly posed in ophthalmic clinical trials. METHODS CVFQ(More)
PURPOSE To identify specific health-related quality of life (HRQOL) concerns affecting children with esotropia as expressed by children or one of their parents (proxy) and concerns affecting the parents themselves. METHODS Sixty children with esotropia (0-17 years of age) and 1 parent for each child were prospectively enrolled. Individual semistructured(More)
BACKGROUND Good long-term visual acuity outcomes for children with dense congenital unilateral cataracts have been reported after early surgery and good compliance with postoperative amblyopia therapy. However, treated eyes rarely achieve normal visual acuity, and there has been no formal evaluation of the utility of the treated eye for reading. METHODS(More)
INTRODUCTION AND PURPOSE A number of studies have evaluated visual acuity (VA) of special needs children, but no analyses of the parents' perception of VA testing or the utilization of VA test results by pediatric ophthalmologists have been reported. PATIENTS AND METHODS Special needs children referred for an initial VA test (Teller Acuity Cards) during a(More)
