Adult albinos and human infants share a number of common visual characteristics: both have low grating acuity, both lack a foveal pit (foveal hypoplasia), and both have much lower central cone densities than in the normal adult. We have explored the consequences of these characteristics by measuring both spatial and temporal contrast sensitivity in the(More)
The goal of this study was to determine the frequency of ophthalmic disorders in a group of young children with Down syndrome who were unselected for ophthalmic abnormalities, and to determine whether examination by a pediatric ophthalmologist should become standard practice. Of 77 children referred to a Down syndrome clinic at a teaching hospital and(More)
Previous experiments testing grating and vernier acuities in albino central vision are consistent with the hypothesis that the deficit in their monocular spatial processing is mainly due to the increased spacing of their foveal cones. This was tested by measuring albino spatial frequency discrimination over the range 0.25-4.0 cpd. The same experiments were(More)
Lymphocytic choriomeningitis virus (LCMV) is an underdiagnosed fetal teratogen. This diagnosis should be considered for infants and children with unexplained hydrocephalus, micro- or macrocephaly, intracranial calcifications, chorioretinitis, and nonimmune hydrops. The immunofluorescent antibody test is the only reasonable, commercially available, screening(More)
A masking paradigm was used to measure the spatial frequency and orientation tuning of spatial mechanisms in the albino visual system. Threshold elevation curves obtained in this manner at test spatial frequencies of 0.25 cycles/deg (cpd), 0.50 cpd, and 1 cpd have the same shape as curves obtained from normal subjects at test frequencies two octaves higher.(More)
OBJECTIVE To determine the incidence of new chorioretinal lesions in patients with congenital toxoplasmosis who were treated throughout their first year of life. DESIGN Prospective longitudinal observation of a cohort. PARTICIPANTS One hundred thirty-two children were studied as part of the longitudinal observation. METHODS One hundred thirty-two(More)
OBJECTIVES The purpose of this work was to determine whether visual impairment caused by toxoplasmic chorioretinitis is associated with impaired performance of specific tasks on standardized tests of cognitive function. If so, then we worked to determine whether there are patterns in these difficulties that provide a logical basis for development of(More)
Light-adapted and dark-adapted electroretinograms were obtained in 27 premature infants who were screened for retinopathy of prematurity shortly after birth. Thirteen showed no retinopathy and 13 had mild to moderate retinopathy, which ranged from stage I, zone III (International Classification) to stage III, zone II. Measurements were made during the first(More)
Retinoblastoma is the most common intraocular tumor in children. Current management includes broad-based treatments such as chemotherapy, enucleation, laser therapy, or cryotherapy. However, therapies that target specific pathways important for retinoblastoma progression could provide valuable alternatives for treatment. MicroRNAs are short, noncoding RNA(More)
The seventh family manifesting an entity described as automosal dominant optic atrophy with hearing loss is reported here. This disorder shows great inter- and intrafamilial variation in the onset time and the degree of loss of both vision and hearing. Unlike autosomal dominant optic atrophy without hearing loss, it appears to be associated with a red-green(More)
