A MODEL FOR DEMONSTRATING OCULAR REFRACTION

Optometry and Vision Science, 1972
ABSTRACT A method of constructing a model eye composed of a corneal lens and a crystalline lens contained in aqucous solution is demonstrated, By use of laser illumination, one is able to construct a bundle of rays whose path clearly demonstrates the nature of ocular refraction.

Ocular anatomy and refraction

Documenta Ophthalmologica, 1983
An examination is made of possible relations between ocular morphology and refraction in man. Special attention is paid to astigmatism, prematurity, the eye at birth, and differences as between the eyes of men and women respectively. Some functional correlates are also pointed out.

Hormonal influences on ocular refraction in the rat

Nature, 1978
WE report here that thyrotrophin (TSH) has a marked influence on ocular refraction in rats. In the clinical experience of one of us (C.C.K.-V.A.), adolescent myopia is not infrequently accompanied by increased height, suggesting a common, possibly hormonal, cause for both phenomena.

Ocular refraction at low illuminations

Vision Research, 1966
Abstract A survey of literature concerned with ocular refraction at reduced illuminations reveals that most eyes become myopic with approaching darkness. The three causes of this myopia are considered and evidence for a night near response presented.

Refractive error and ocular motility in plagiocephaly

Child's Nervous System, 1994
Plagiocephaly, which is caused by premature closure of one of the coronal sutures, leads to fronto-orbital asymmetry. The aim of this work was to study the repercussions of orbital deformation on the visual system. Twenty-one patients presenting with plagiocephaly at birth and operated on by the same craniofacial technique (bilateral approach with ...

Changes in ocular dimensions and refraction with accommodation

Ophthalmic and Physiological Optics, 1997
The purpose of this study was to measure the changes in ocular dimensions with accommodation, with particular reference to the radius of curvature of the posterior surface of the crystalline lens. The increase in power of the eye with accommodation is considered to arise primarily from a decrease in the radius of curvature of the anterior surface of ...

Ocular Torticollis Caused by Refractive Error

Archives of Ophthalmology, 1982
• A patient with bilaterally dislocated lenses assumed a head tilt for optimum vision through spectacles prescribed for her myopia. Phakic and aphakic refractions could be obtained in either eye with changes in head position. A unilateral aphakic contact lens provided useful vision and corrected the head tilt.

Ocular Integrity after Refractive Procedures

Ophthalmology, 1997
The purpose of the study was to determine the integrity of human eyes after refractive procedures.Whole human globes underwent either radial keratotomy (RK) with eight incisions, automated lamellar keratoplasty (ALK), photorefractive keratectomy (PRK), or excimer laser assisted in situ keratomileusis (LASIK).

Heritability of refractive value and ocular biometrics

Experimental Eye Research, 2008
The aim of this work was to analyse genetic influences on ocular refractive value and axial length using the hypothesis of a polygenic control. The genealogical records of 55 families were used in the analyses. The cohort included 723 individuals and clinical data were collected for 445 individuals with a mean age of 37.86 years.

Ocular Refractive Characteristics in Cerebral Palsy

Archives of Pediatrics & Adolescent Medicine, 1961
This study was undertaken because of the clinical impression that ocular refractive errors in cerebral palsied children were different from those of normal children and of children with neuromuscular handicaps other than cerebral palsy. A study of a limited number of patients warrants some preliminary observations.
