Retinal image in axial and refractive ametropia.
THERE are some features relative to the size of the retinal images in these two conditions which are of general interest, though they are rarely discussed. Axial Ametropia.-The " basic " (blurred) retinal image is smallest in hyperopia, intermediate in emmetropia, and largest in myopia. The size of a blurred retinal image is best taken from the points in the diffusion circles at the extremities...
متن کاملDistribution of axial, corneal, and combined ametropia in a refractive surgery unit.
PURPOSE To group eyes in our refractive surgery unit on the basis of the origin of their ametropia and to assess the percentage of eyes in the different groups. METHODS Refractive parameters and the axial eye length (AL) of 131 eyes of 131 persons with different refraction were measured. The eyes were initially classified into five groups on the basis of the grade of their ametropia: hypermet...
متن کاملImage defocus and altered retinal gene expression in chick: clues to the pathogenesis of ametropia.
PURPOSE Because of the retina's role in refractive development, this study was conducted to analyze the retinal transcriptome in chicks wearing a spectacle lens, a well-established means of inducing refractive errors, to identify gene expression alterations and to develop novel mechanistic hypotheses about refractive development. METHODS One-week-old white Leghorn chicks wore a unilateral spe...
متن کاملCiliary muscle morphologic changes with accommodation and axial ametropia.
PURPOSE To use anterior segment optical coherence tomography (AS-OCT) to analyze ciliary muscle morphology and changes with accommodation and axial ametropia. METHODS Fifty prepresbyopic volunteers, aged 19 to 34 years were recruited. High-resolution images were acquired of nasal and temporal ciliary muscles in the relaxed state and at stimulus vergence levels of -4 and -8 D. Objective accomm...
متن کاملInfluence of refractive error and axial length on retinal vessel geometric characteristics.
PURPOSE To evaluate the influence of refractive error and axial length (AL) on retinal vascular network geometry measurements in an adult Asian population. METHODS This was a population-based, cross-sectional study on 2882 persons with diabetes in the Singapore Malay Eye Study. Spherical equivalent refraction was assessed using an autokeratorefractometer and subjective refraction. AL retinal ...
