There are six noticeable differences in retinal image quality in just one line of visual acuityHe stressed that visual acuity is in fact a poor performance metric. “It is therefore not surprising that cross-sectional studies correlating measures of retinal image quality and visual performance have been only moderately impressive,” he pointed out. So what connects the two? “The visual Strehl and neural strength tests are excellent metrics of visual image quality that are highly correlated with visual performance as measured by acuity,” explained Dr Applegate, suggesting that clinical investigators focus on these metrics.
