Abstract:
Two methods have been described for measuring tonic accommodation (TA) under clinical conditions. One is the near retinoscopy (NEAR) method; the other uses Nott retinoscopy as the patient views a low spatial frequency difference of Gaussian (DOG) target. The purpose of this study was to compare the TA measures made by these two procedures on a group of 6- to 14-year-old children. The data indicate that the procedures yield significantly different information.
