Many diseases, such as glaucoma, start out with no symptoms at all. Eventually if left undetected, however, these conditions can have devastating results, even causing blindness. As part of a complete eye examination we look at the whole eye, not just evaluating if you can read 20/20 or not. The saying goes that the eye is the window to your soul, but it is also the window into what’s going on in the rest of your body as well. A dilated eye exam often allows us to see conditions before they show up elsewhere. Common problems that can sometimes be picked up in the eye before elsewhere in your body include diabetes, high blood pressure, high cholesterol, multiple sclerosis, and other auto-immune disorders.
