Other Eye Exams May Be Conducted
Eye doctors look for yellow deposits located beneath the retina known as drusen when performing a dilated eye exam. In addition to a dilated eye exam, an eye doctor may perform an optical coherence tomography, which is an ultrasound that uses light waves to take pictures of the tissues in the eye to search for abnormalities. Amsler grid is a test that can be used to verify a person's central vision accuracy. Fluorescein angiograms occur when a dye is injected into the patient's arm, and pictures are taken as the dye passes through the blood vessels in the eyes.
