Have you ever wondered if your body was showing a symptom of a future illness that no one caught from your annual physical? Ever thought about why your Optometrist or Ophthalmologist always prefers to dilate you? Well, it isn’t for torture. The truth is your eyes can portray lots of things related to your health that other tests cannot. Dilation expands your pupil giving a view to the very back. In the back portion of your eye your doctor is able to see blood vessels, the macula, and optic nerve, just to touch on a few. Abnormal blood vessels or new blood vessel growth in the retina could be one sign of diabetic retinopathy that is likely not visible without dilation or retinal fundus photography.
