Glaucoma is detected through a comprehensive eye exam that includes:
Visual acuity test. This eye chart test measures how well you see at various distances.
Tonometry. An instrument measures the pressure inside the eye. Numbing drops may be applied to your eye for this test.
Visual field test. This test measures your side (peripheral) vision. It helps your eye care professional tell if you have lost side vision, a sign of glaucoma.
Dilated eye exam. Drops are placed in your eyes to widen, or dilate, the pupils. Your eye care professional uses a special magnifying lens to examine your retina and optic nerve for signs of damage and other eye problems.
Pachymetry. Your eye care professional uses an ultrasonic wave instrument to measure the thickness of your cornea
Retinal scan(OCT)- To check the change in thickness of your retina
Fundus photography-Photograph of your retina is taken for future reference to document any change in your nerve.
