(Group 1 is composed of subjects in whom the corrected location point of the superior peak was ≤ 48.78 in one or both eyes. Group 3 is composed of subjects in whom the corrected location point of the superior peak was ≥ 62.86 in one or both eyes. Group 2 is composed of subjects in whom the corrected location point of the superior peak was between 48.78 and 62.86 in both eyes.)
