An optometrist or ophthalmologist will usually do the following to check for glaucoma:

• Ask whether you have any risk factors for glaucoma.
• Check your vision.
• Measure the fluid pressure inside your eyes.
• Measure the thickness of your cornea (the clear front surface of the eye).
• Check side and central vision. Glaucoma usually affects vision on the side, which is harder to notice than the loss of central vision.
• Look at your retina (the inner surface of your eye).
• Check your optic nerve for signs of damage.
• Do additional tests if needed.
