To help the doctor with general screening of the health of your eyes you may have a test called an OCT. This test provides an incredibly detailed overview of the health of crucial structures in your eyes such as the optic nerve and macula. A visual field test provides information on how your eyes are functioning and remains the gold standard test in glaucoma management. A Pentacam is another test that provides exceptional anatomical detail and data on the refractive or focusing power of the eye. Further information is provided in the links below.
