Does astigmatism alter with cycloplegia?
To determine the effect of the cyclopentolate 1% on the cylindrical and spherical components of the refraction.Three hundred seventy-five eyes of 195 subjects, including 74 males and 121 females, aged from 3 to 59 years were refracted before and 30 min after cyclopentolate 1% eye drop instillation. To compare cylindrical data, power vector analysis (J0

Purpose To explore the influence of myopia during different spectacle correction status on binocular vision function. Methods A total of 1446 myopic patients (2892 eyes) with different glasses‐wearing states, with a mean age of 22.38 ± 4.74 years, were randomly selected from the Corneal Refractive Department of Jinan Mingshui Eye Hospital between ...

Abstract Purpose To evaluate the effectiveness of 12 months of spectacle lens wear incorporating cylindrical annular refractive elements (CARE) in slowing myopia progression compared to single vision (SV) spectacle wear. Methods In an ongoing 2‐year prospective, double‐masked, multi‐centre clinical trial, 240 Chinese children aged 6–13 years, spherical

Abstract Purpose To investigate 2‐year changes in macular choroidal thickness (ChT) in children receiving 0.01% atropine eyedrops and its relationship with spherical equivalent refraction (SER) progression and axial length (AL) elongation. Methods A total of 250 myopic children aged 6–16 years (167%–0.01% atropine, 83‐placebo) were enrolled in the ...

Assumption-free estimation of the genetic contribution to refractive error across childhood [PDF]
Purpose: Studies in relatives have generally yielded high heritability estimates for refractive error: twins 75–90%, families 15–70%. However, because related individuals often share a common environment, these estimates are inflated (via misallocation ...
