Journal ArticleDOI
Cortical magnification factor predicts the photopic contrast sensitivity of peripheral vision.
TL;DR: The results indicate that peripheral contrast sensitivity and acuity are inferior to foveal performance, because of the diminished cortical projection area.
Journal Article
Resolution of gratings oriented along and across meridians in peripheral vision.
TL;DR: The origin of the oblique effect seems to be neural because it was not caused by peripheral refractive errors or optical distortion of the peripheral retinal image, and resolution was systematically best for meridionally oriented grating Bars and worst for grating bars perpendicular to the visual-field meridians.
Journal ArticleDOI
Temporal contrast sensitivity and cortical magnification.
TL;DR: It is concluded that central and peripheral vision are qualitatively similar in spatiotemporal visual performance.
Journal ArticleDOI
Contrast sensitivity in evaluation of visual impairment due to diabetes
TL;DR: Both visual acuity and contrast sensitivity measurements are useful in the evaluation of the nature of visual impairment due to diabetic eye disease.
Journal ArticleDOI
Critical flicker frequency and M-scaling of stimulus size and retinal illuminance.
Jyrki Rovamo,Antti Raninen +1 more
TL;DR: Using various stimulus areas and luminances, monocular critical flicker frequency (CFF) was measured as a function of eccentricity in the temporal visual field and was not independent of visual field location when stimulus area was scaled by the magnification factor of the human striate cortex.
