Retinal imaging is the ability to either photograph or take a picture if you will an image of the back of the retina. When we look inside an eye during an eye exam we can observe the blood vessels, we can observe the retinal tissue and any of the subtle changes that exist. Normally we would write those changes or maybe slight abnormalities down not that they are serious or can cause vision loss but just to note them so we would know the next time we looked in the eye if there is a change or deviation from the first visit that we had. When we have a picture of an eye or retinal imaging we can look at that image look inside the eye and compare to notice even the most subtle change that exists. This allows us to be more effective in that patient’s care and management.
