Loss of depth perception in older adults

Depth perception in elderly adults
One often overlooked aspect of vision loss that many adults experience as they age is loss of depth perception. Older adults are 10 times more likely to lose depth perception and be at increased risk of falls and the often serious injuries that result. Early detection and treatment are key to reducing the risk of serious injuries.

A new study published in the journal, Optometry & Vision Science, examined one cause of depth perception loss: anisometropia.  The study has confirmed what we already know from working with with elderly patients in our Vancouver optometry clinic: changes in the eyes as we age can degrade our ability to see depth (stereopsis) and in three dimensions (3D vision).

One famous example of a case of depth perception loss and successful treatment using optometric vision therapy rehabilitation is the case of the father of neuroscientist Susan Barry, which you can read about here.
