Peripheral refraction and retinal contour in stable and progressive myopia.
PURPOSE To compare the patterns of relative peripheral astigmatic refraction (tangential and sagittal power errors) and eccentric eye length between progressing and stable young-adult myopes. METHODS Sixty-two right eyes of 62 white patients participated in the study, of which 30 were nonprogressing myopes (NP group) for the last 2 years and 32 were progressing myopes (P group). Groups were m...
متن کاملRetinal stretching limits peripheral visual acuity in myopia
Axial elongation of the myopic eye has the potential to stretch the retina, thereby reducing the sampling density of retinal neurons. Resolution acuity in the peripheral field of normal eyes is known to be sampling-limited, which suggests that retinal stretching in the myopic eye should have a direct effect on resolution acuity everywhere in the visual field except perhaps the fovea, which is u...
متن کاملPeripheral retina in myopia. With particular reference to retinal breaks.
Since Gonin (1921, 1930) established the role of retinal breaks in the aetiology of retinal detachment, the closure or isolation of retinal breaks has become an essential part of all procedures for the treatment of this condition. The "prophylactic" treatment of retinal breaks is practised in many centres, but in recent years it has been shown that asympto-matic retinal breaks without detachmen...
متن کاملPeripheral refraction in different ethnicities.
PURPOSE Peripheral refraction is commonly used to infer retinal shape. Because of the different prevalence of myopia in the white compared with East Asian populations, peripheral refraction along the horizontal meridian was compared in white and East Asian young adults with emmetropic, low myopic, and moderately myopic refractive errors. METHODS Thirty-five white and 37 East Asian subjects we...
متن کاملPeripheral refraction along the horizontal and vertical visual fields in myopia
Peripheral refractions were measured to 35 degrees eccentricity using a free-space autorefractor in young adult emmetropic and myopic subjects. Refractions were measured along horizontal and vertical visual fields for 116 subjects and a 43 subject subset, respectively. Along the horizontal visual field, peripheral myopic shifts in spherical equivalent M of emmetropes changed to relative hyperme...
