Dr. John J. Guerriero demonstrates a retinal camera that makes images of the interior of patients eyes and enables the optometrist to view blood vessels and determine if there is damage from conditions such as diabetes and macular degeneration. Unlike the old days, when the doctor had to remember from examination to examination, the images of the eye can be kept from year to year to make comparisons to determine if a condition has changed.
