Why be Dilated?

External examination of the eye includes evaluation of the cornea, eyelids, conjunctiva and surrounding eye tissue using bright light and magnification.

Evaluation of the lens, retina and posterior section of the eye may be done through a dilated pupil to provide a better view of the internal structures of the eye. Without drops to dilate the pupil, which holds the pupil open when bright light is shown into the eye, your eye doctor cannot accurately evaluate all the necessary structures inside the eye.
