What is an ophthalmoscopy test?

Ophthalmoscopy (say "awf-thul-MAW-skuh-pee") is a test that lets your doctor see the inside of the back of your eye. Your doctor looks at the eye using a magnifying scope (an ophthalmoscope) and a light source.

Why is an ophthalmoscopy test done?

Ophthalmoscopy is done to:

  • Find problems or diseases of the eye, such as retina problems.
  • Help find other conditions or diseases that damage the eye.
  • Look for the cause of symptoms, such as headaches.
  • Find other problems or diseases, such as head injuries or brain tumors.

This exam is usually done as part of a regular eye exam. Other eye tests that may be done include vision testing and testing for glaucoma.

How is an ophthalmoscopy test done?

Tell your doctor if you or someone in your family has glaucoma. And tell your doctor if you are allergic to any type of eyedrops.

Your doctor will shine a bright light in your eyes. Then the doctor will look at your eyes.

Before the test, your doctor may use eyedrops to widen (dilate) your pupils. This helps the doctor see the back of the eye. Your doctor may also use drops to numb your eyes. It takes about 15 to 20 minutes to fully dilate the pupils.

How do you prepare for an ophthalmoscopy test?

In general, there's nothing you have to do before this test, unless your doctor tells you to.

What do the results of an ophthalmoscopy test mean?

Ophthalmoscopy results

Normal:

  • All of the structures inside the eye look normal.

Abnormal:

  • The retina is detached.
  • Swelling of the optic nerve (papilledema) is found.
  • Optic nerve damage caused by glaucoma is found.
  • Changes in the retina (such as hard, white deposits beneath the retina called drusen, or broken blood vessels called hemorrhages) point to macular degeneration.
  • Damaged blood vessels or bleeding in the back of the eye is seen. This could be caused by diseases such as high blood pressure or diabetes.
  • Cataracts are found.
