The purpose of the present paper was to analyze the efficiency of an abbreviated, albeit objective posturographic test as an indicator of fatigue. Posturography was measured in 10 healthy adults (age 18-33 years, male/female 7/3). Baseline posturographic measurements were taken for each subject. Later, a shorter (3-min) posturographic test was administered(More)
BACKGROUND Fatigue is one of the main causes for accidents in transportation. This study was designed to assess the efficacy of a short objective posturographic test as an indicator of fatigue due to sleep deprivation. OBJECTIVES To assess the efficiency of a short objective posturographic test as an indicator of fatigue due to sleep deprivation. (More)
PURPOSE To determine the changing prevalence of myopia during the years 1990 through 2002 among the 16- to 22-year age group and identify possible risk factors. METHODS A retrospective study, based on 13 repeated prevalence surveys conducted over a 13-year period. The study subjects were all Israeli nationals belonging to the 16- to 22-year age group from(More)
PURPOSE Falls are a significant cause of morbidity in the elderly. Because decreased vision is known to be a significant risk factor for falling in this age group, we sought to examine the effect of the removal of cataract, a major cause of visual handicap, on postural stability. METHODS Postural stability was measured in 23 patients who underwent(More)
Continuous exposure of chicks to light was shown to result in severe hyperopia, accompanied by anterior segment changes, such as severe corneal flattening. Since rearing chicks in complete darkness results only in mild hyperopia and minor changes in corneal curvature, we hypothesized that light intensity may play a role in the development of refractive(More)
PURPOSE To identify the genetic cause underlying autosomal recessive cone-rod dystrophy (CORD) and high myopia. METHODS Nine members of a consanguineous Arab family were clinically examined and were given fluorescein angiography (FA), biometry, and full field electroretinogram (ERG) testing. Blood samples were collected for DNA extraction. A homozygousity(More)
Opsoclonus is a rare childhood ocular motility disorder characterized by irregular, chaotic, involuntary bursts of high amplitude, back-and-forth oscillations of the eyes,without pause intervals. Although this disorder is associated with neuroblastoma and other neural crest tumors, as well as with other neurologic abnormalities, it was also reported in(More)
PURPOSE To find correlations between convergence amplitude and reading ability, as assessed in various methods. METHODS Convergence of 66 children aged 8-10 years was evaluated using 1) Non-accommodative target at near and distance; 2) A near computerized stereogram; and 3) Measurement of near point of convergence (NPC). Reading ability was examined by:(More)
PURPOSE To evaluate the influence of some widely used antiglaucoma agents on angiogenesis in a novel rat cornea model. METHODS Angiogenesis was induced in 32 rats by slow-release polymer pellets containing basic fibroblast growth factor (bFGF) placed in a corneal micropocket. Angiogenesis was later measured and compared in groups of rats given one of four(More)
PURPOSE To determine the rate of amblyopia in native Jewish Israelis compared with those who immigrated from the former Soviet Union (U.S.S.R.) after they were 10 years of age. METHODS Health records of all 16-year-old subjects examined in the Israel Defense Forces Recruitment Center between 1998 and 2003 were analyzed. The number of subjects with best(More)
