Errors of Refraction and Their Sequele
In theory no doubt any existing refractive error should be found and treated, so that the individual may enjoy the most perfect optical conditions possible. But it must always be borne in mind that the eyes are only part of the living organism, dependent on the whole, deriving from it and adding to it. This may modify the position. A comfortable and efficient ocular mechanism depends on much mo...
متن کاملModes of inheritance of errors of refraction.
Eighteen families in which both parents had refractions within the range of + 4 0 D to 4 0 D and axial lengths seen in emmetropia (22.3-26-0 mm) showed coefficients of correlation of the order 0 5 indicative of polygenic inheritance. Such coefficients were seen for axial length (0.407) and for the cornea (0-487), but not for the lens (which is known to be yoked to the axial length). No such coe...
متن کاملImage Processing and Analysis to Diagnose Ocular Refraction Errors
We describe ongoing research on the development of a functional system for diagnosing and measuring ocular refractive errors in the human eye (astigmatism, hypermetropia and myopia) by automatically analyzing images of the human ocular globe acquired with the Hartmann-Shack (H-S) technique. H-S images are to be input into a system capable of recognizing the presence of a refractive error and ou...
متن کاملPeripheral refraction profiles in subjects with low foveal refractive errors.
PURPOSE To study the variability of peripheral refraction in a population of 43 subjects with low foveal refractive errors. METHODS A scan of the refractive error in the vertical pupil meridian of the right eye of 43 subjects (age range, 18 to 80 years, foveal spherical equivalent, < ± 2.5 diopter) over the central ± 45° of the visual field was performed using a recently developed angular sca...
متن کاملInborn errors of metabolism causing epilepsy.
Seizures may be the first and the major presenting feature of an inborn error of metabolism (IEM), for example in a neonate with pyridoxine-dependent epilepsy. In other IEMs, seizures may be preceded by other major symptoms: by a reduced level of consciousness in a child with an organic acidaemia or urea cycle defect; or by loss of skills, progressive weakness, ataxia, and upper motor signs in ...
