People say that the eyes are the windows to the soul yet they are actually a window to your health. Many people are unaware how many health issues can be detected or diagnosed in an eye exam.
The eye has two unique properties. The first is that the tissue on the back of the eye, the retina, is the only place in the body where blood vessels can be seen without any obstruction of other tissue. By examining the appearance of these blood vessels, your optometrist can see damage from systemic disease happening to the eye and if it is happening to the eye then it is also happening to the blood vessels throughout the body.
