“…The current descriptions of retinal shape were based only on the spherical equivalent refractive error. It has been suggested that the pattern of peripheral astigmatism indicates the unique growth mechanisms at different regions of the retina 30 . However, in the present study, no significant differences between SV and DIMS lenses were found with regard to changes in astigmatism.…”

“…It has been suggested that the pattern of peripheral astigmatism indicates the unique growth mechanisms at different regions of the retina. 30 However, in the present study, no significant differences between SV and DIMS lenses were found with regard to changes in astigmatism. Thus, investigation of the vertical peripheral refraction (and astigmatism), that could provide a more accurate retinal shape is warranted.…”

It has been suggested that the peripheral retina plays an essential role in eye growth and emmetropisation as there are more retinal neurons in the periphery than in the central fovea. 1 Numerous animal studies have suggested that peripheral visual input through form deprivation and lens induction could also guide eye growth. [2][3][4] The earliest proposal that peripheral refraction led to human myopia development came from Hoogerheide et al. 5 They measured refractive error in the horizontal visual field of young hyperopes and emmetropes who

“…On the other hand, the study by Li et al [27] provides a quantitative reference for the impacts of the expansion in retinal contour on ocular aberrations. This is useful for the wide-angle eye modeling procedure, indicating that finer modeling of the retinal contour is required to achieve a more accurate prediction of peripheral defocus at the last step of the eye modeling procedure.…”

Background: To assess retinal and optical changes associated with near vision reading for different lighting conditions in electronic screens. Methods: Twenty-four young healthy subjects participated in the study; an iPad and an Ebook were chosen as stimuli for 5 min of reading task with different lighting conditions. Central and peripheral retinal thicknesses in the macular ETDRS areas by optical coherence tomography were analyzed. Results: Significant differences were found between basal retinal thickness and retinal thickness after reading with iPad and high illumination, in the N6 (p = 0.021) and I6 (p = 0.049) areas, and low illumination (S3: p = 0.008, N3: p = 0.018, I3: p = 0.021, N6: p = 0.018 and I6: p = 0.020), being thinner after reading. The same trend was observed after reading with an Ebook and high lighting in the N3 (p = 0.037) and N6 (p = 0.028). For low lighting conditions, only retinal thinning was observed. After reading, retinal shape analysis revealed significant changes from computed basal eccentricity for high lighting conditions only. At the periphery, those differences in eccentricity values were statistically significant for both lighting conditions. Conclusions: Young people can recover visual quality after 5 min of reading tasks at different lighting levels on electronic devices, while peripheral retinal expansion remains altered, especially at low lighting levels.
