CHANGES IN AXIAL LENGTH AND OTHER DIMENSIONS OF THE EYEBALL WITH INCREASING AGE

A significant reduction in axial length of the eyeball with increasing age was found when one essentially normal eye of each of 72 persons was studied (p < 0.01). In 53 of these subjects, the horizontal diameter of the cornea also became less with increasing age (p < 0.01). Lens thickness became greater and anterior chamber depth less (p < 0.001 each). “Against‐the‐rule”, rather than “with‐the‐rule” corneal astigmatism was found in old age (p < 0.001).
