DESIGN Cross-sectional, population-based study. PARTICIPANTS White and African American children aged 6 through 71 months in Baltimore, MD,(More)
OBJECTIVE To evaluate the effectiveness of treatment of amblyopia in children aged 7 to 17 years. METHODS At 49 clinical sites, 507 patients with amblyopic eye visual acuity ranging from 20/40 to 20/400 were provided with optimal optical correction and then randomized to a treatment group (2-6 hours per day of prescribed patching combined with near visual(More)
OBJECTIVE To demonstrate spontaneous regression of large, clinically symptomatic optic pathway gliomas in patients with and without neurofibromatosis type 1 (NF-1). METHODS Patient cases were collected through surveys at 2 consecutive annual meetings of the North American Neuro-Ophthalmology Society (NANOS) and through requests on the NANOSNET Internet(More)

STUDY POPULATION Patients with unilateral strabismic, anisometropic, or combined amblyopia. OBSERVATION Fast RNFL analysis with ocular coherence tomography (OCT)(More)
PURPOSE To report a computerized method for determining visual acuity in children using the Amblyopia Treatment Study visual acuity testing protocol. METHODS A computerized visual acuity tester was developed that uses a programmed handheld device that uses the Palm operating system (Palm, Inc, Santa Clara, California). The handheld device communicates(More)
PURPOSE To determine the age-specific prevalence of refractive errors in white and African-American preschool children. DESIGN The Baltimore Pediatric Eye Disease Study is a population-based evaluation of the prevalence of ocular disorders in children aged 6 to 71 months in Baltimore, Maryland.

Strabismus has been known to have a significant genetic component, but the mode of inheritance and the identity of the relevant genes have been enigmatic. This paper reports linkage analysis of nonsyndromic strabismus. The principal results of this study are: (i) the demonstrated feasibility of identifying and recruiting large families in which multiple(More)
PURPOSE Demographic and outcome data in the era of modern neuroimaging are needed to describe pseudotumor cerebri in children. METHODS We reviewed the medical records of children less than 18 years old who were diagnosed with pseudotumor cerebri between 1977 and 1997. We defined pseudotumor cerebri as (1) increased intracranial pressure, (2) normal or(More)
This study evaluated the ophthalmological outcome following sixth nerve palsy or paresis in 64 children 7 years of age and younger. The outcomes considered were vision, residual strabismus and the need for strabismus surgery. Etiologies included tumor, hydrocephalus, trauma, infection, malformation, and idiopathic and miscellaneous causes. Strabismus(More)
