Optomap« allows an unprecedented view of the retina - the back of the eye - using state of the art technology and without the need for drops to dilate the eye.

The retina is like the film of your eye's "camera", lining the back inside surface of the eyeball and capturing light entering through the pupil.  These light signals are gathered together and transmitted through nerve cells on the retina via the optical nerve (your "blind spot") to the brain.  The brain then interprets the signals as an image which we perceive as sight.  In the normal eye this process goes on without us being aware of it, but occasionally something goes wrong and the pathways may be disrupted, leading to a disturbance in our vision.  Optomap« shows us if the problem lies within the retinal tissues. 

But sometimes the disturbance does not affect our vision at first, and we may be unaware that anything is amiss.  That's where Optomap« really comes into its own, allowing the Optometrist to detect changes before they affect our sight, and in many cases this will give us time to have interventional treatment if that is available.

Normally by using the conventional ophthalmoscope, the Optometrist can see up to a 30║ angle of the retina, but with Optomap« technology this improves to up to 200║.   The analogy we like to use is being able to see right into a room by opening the door, rather than trying to see it through the keyhole.  The difference is "night and day" for the Optometrist as he is able to see so much more than ever before.

All of the above images provide about  6-7 times greater field of view than even a dilated eye using the conventional ophthalmoscope.
