Twins and neural tube defects.
The hypothesis that anencephalus stems from fetus-fetus interactions in dizygotic twin pairs is examined by comparing the epidemiological predictions of the hypothesis with available observations. The hypothesis itself was based upon the disease-discordance and sex-concordance characteristics of twin pairs affected with anencephalus, and upon the sex ratio of the disease itself. The testable pr...
متن کاملConvergent strabismus, macular foci and toxoplasmosis in monozygotic twins.
IN an earlier paper, one of us (Granstrdm) described a number of cases of convergent strabismus in monozygotic twins; both " concordance " and " discordance " occurred. Concordance suggests a hereditary genesis, but the latter does not exclude discordance (i.e., genotypical asymmetry according to Dahlberg's theory). A monozygotic pair of twins will be described, in whom, despite pronounced conc...
متن کاملVoluntary unilateral convergent strabismus of either eye.
Case Report A male Hindu doctor aged 28 years reported on October 10, 1962, with the complaint of difficulty in reading (the letters appearing mixed together after reading for some time) for the past 8 years. He had had many pairs of spectacles, all for compound hypermetropia, without relief of symptoms. About 6 years ago, he had been advised to do convergence exercises, first looking at a dist...
متن کاملPerception via the deviated eye in strabismus.
Misalignment of the eyes can lead to double vision and visual confusion. However, these sensations are rare when strabismus is acquired early in life, because the extra image is suppressed. To explore the mechanism of perceptual suppression in strabismus, the visual fields were mapped binocularly in 14 human subjects with exotropia. Subjects wore red/blue filter glasses to permit dichoptic stim...
متن کاملThe Australian Twins Eye Study
Research into the genetic effects and specific genes associated with retinal vascular caliber, a risk marker of cardiovascular diseases, may provide new insights into the genetic contribution of early microvascular disease. A combined 374 monozygotic and 536 dizygotic twin pairs and 322 siblings from the Twins Eye Study in Tasmania and the Brisbane Adolescent Twin Study underwent complete ophth...
