Association of number of foci and specks per eye (n=101)1 with visual function in the eye that underwent dark adaptation testing.2

Number of foci per eye Number of specks per eye
Correlation coefficient p-value Correlation coefficient p-value
Best-corrected visual acuity (logMAR) 0.15 0.1264 0.16 0.1082
Contrast sensitivity (log sensitivity) −0.14 0.1786 −0.22 0.0278
Low luminance acuity (logMAR) 0.25 0.0117 0.33 0.0010
Low luminance deficit 0.20 0.0513 0.29 0.0031
Mesopic light sensitivity −0.15 0.1957 −0.36 0.0018
Scotopic light sensitivity −0.16 0.1695 −0.46 <0.0001
Rod-mediated dark adaptation (RIT) 0.38 <0.0001 0.57 <0.0001

RIT=rod intercept time; MAR=minimum angle of resolution

101 participants (eyes) underwent all visual function testing except mesopic and scotopic light sensitivity, which 75 participants (eyes) completed

Association from Pearson partial correlation coefficient, adjusted for age. For positive correlations, increases in the value associated with the visual function test indicate worse function. For negative correlations, decreases in the value associated with the visual function test indicate worse function. While not all associations are significant, all correlations show poorer function with increases in the number of foci and specks.
