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

• Ask if you have any risk factors for glaucoma.
• Check how well you can see.
• Measure the pressure inside your eyes.
• Measure the thickness of your cornea (the clear front part of your eye).
• Check your side and central vision. Glaucoma often affects side vision first, which can be hard to notice.
• Look at your retina (the inside back part of your eye).
• Check your optic nerve for signs of damage.
• Do other tests if needed.
