Examining the entire retina is critical. Some of the most pervasive eye diseases, such as retinal tearing, tumors, and macular degeneration, occur in the far periphery of the eye, making them difficult to detect. Symptoms often do not show up in the early stages and vision may not be affected until there is significant and unrecoverable damage.
The ultra-widefield retina exam is beneficial even if you feel your eyes are healthy. By examining the health of your fundus periodically, your eye doctor can view images from year to year and detect subtle changes in your eyes over time. These changes could go unnoticed and can be the sign of early changes in your eye health.
