First of all, it saves a great deal of time for the patient and our doctor. Secondly, it does a better job assessing the inside of the eye. Unlike dilation or any other retinal imaging device, Optomap allows the doctor to see over 80% of the retina, which helps him detect problems more quickly and easily. It also allows the digital image to be reviewed with the patient and saved for future review and comparisons. Last, but not least, it does not interfere with vision testing, contact lens evaluation, or the selection of new glasses or sunglasses. These are common problems with dilation.
