X-linked congenital stationary night blindness (CSNB) is a recessive non-progressive retinal disorder characterized by night blindness, decreased visual acuity, myopia, nystagmus and strabismus. Two distinct clinical entities of X-linked CSNB have been proposed. Patients with complete CSNB show moderate to severe myopia, undetectable rod function and a(More)
To assess the natural history of optic pathway tumors (OPT) in children with neurofibromatosis type 1 (NF-1), from January 1985 through May 1993 we performed a prospective, longitudinal study of OPT in an unselected population of children with NF-1. Of 227 children with NF-1 seen in a specialty clinic, 176 (77%) underwent neuroimaging. Children in whom(More)
PURPOSE To determine the natural history of treated and untreated congenital toxoplasmosis and impact of this infection on vision. METHODS In this prospective, longitudinal study, 76 newborns were treated with pyrimethamine and sulfadiazine for approximately one year, and 18 individuals not treated during their first year of life entered the study after(More)
Comparisons of lymphocyte surface phenotypes and functions were made among 25 pediatric patients with congenital toxoplasmosis (ages 1 month to 5 years) and 24 uninfected babies, a baby with postnatally acquired infection, and 6 uninfected, 7 recently infected, and 6 chronically infected adults. Percentages of lymphocytes with B1, T11, T3, T4, T8, T6, B4,(More)
Thirty patients with untreated rhegmatogenous retinal detachments underwent complete ocular muscle examinations before scleral buckling procedures. The examination was repeated three weeks, six weeks, three months, and six months after surgery. We found a high incidence of heterotropia after surgery; in most cases this resolved during the first six(More)
Between December 1981 and May 1991, 44 infants and children with congenital toxoplasmosis were referred to our study group. A uniform approach to evaluation and therapy was developed and is described herein along with the clinical characteristics of these infants and children. In addition, case histories that illustrate especially important clinical(More)
Baylisascaris procyonis, the common raccoon roundworm, is a rare cause of devastating or fatal neural larva migrans in infants and young children. We describe the clinical features of two children from suburban Chicago who developed severe, nonfatal B. procyonis neural larva migrans. Despite treatment with albendazole and high dose corticosteroids, both(More)
BACKGROUND Without treatment, congenital toxoplasmosis has recurrent, recrudescent, adverse outcomes. Long-term follow-up of infants with congenital toxoplasmosis treated throughout their first year of life with pyrimethamine and sulfadiazine has not been reported. METHODS Between 1981 and 2004, one hundred twenty infants (current mean age +/- standard(More)
Myopathies are a clinically and etiologically heterogeneous group of disorders that can range from limb girdle muscular dystrophy (LGMD) to syndromic forms with associated features including intellectual disability. Here, we report the identification of mutations in transport protein particle complex 11 (TRAPPC11) in three individuals of a consanguineous(More)
PURPOSE To describe the presenting features and surgical outcomes in a series of children with rhegmatogenous retinal detachments. DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS Thirty-nine eyes of 34 children 18 years of age or younger undergoing surgery for rhegmatogenous retinal detachment. METHODS Patients were(More)
