How are visual impairments diagnosed?

Dr. Jeanne Morrison, PhD
Family Practitioner

In order to detect most visual impairments, your doctor will start with the standard eye chart test. You may have to look through a series of different lenses as well. Sometimes your doctor will shine lights in your eyes and look deep into your pupils for damage to your retina and optic nerve. Your pupils will usually be dilated for this test. Pressure on the optic nerve is checked through a test called tonometry. Finally, communication with your doctor will help determine what may be causing your visual impairment.
