Fundoscopy (Ophthalmoscopy)

Looking inside a person’s eyes is a tried-and-true method for gauging a person’s overall health. And fundoscopy is a test that medical providers of all backgrounds and specialties can use to take in that view. This simple, painless test is a key tool in many types of medical examinations, routine and otherwise.

Overview

Fundoscopy gives an eye specialist a look at the inner back wall of your eye, and some devices can even take photos of it.
Fundoscopy lets your eye care specialist look at and even photograph the inner back wall of your eye.

What is fundoscopy?

Fundoscopy is a simple exam where a healthcare provider uses magnifying tools with an attached light to look into your eyes. It’s a common part of many routine medical exams. And it’s also a common part of diagnosing illnesses, injuries and many other conditions.

The term gets its name from the word “fundus,” the medical term for the inner back wall of your eye. Fundoscopy is also commonly known as ophthalmoscopy (pronounced “off-thal-MOSS-co-pea”) because an ophthalmoscope is one of the tools most often used for it.

There are two types of fundoscopy that a provider can perform, with a specific device for each type:

  • Direct ophthalmoscopy. This type uses a handheld device with a single magnifying window and a mounted light. The light aligns and points at whatever you’re trying to see through the magnifying window. Your provider will sit in front of you, holding this device in their hand and looking through the magnifying window and into your eye.
  • Indirect ophthalmoscopy. This type often uses a ring-shaped frame a provider can wear on their head, with a viewing bar at the front that they can look through with one or both eyes. The provider will also use a handheld condensing lens they hold just in front of your eye. Angling that condensing lens lets your provider get a wider, more magnified view of the back of your eye. If they’re using both eyes, your provider can also see this in 3D.

There’s also a variant of indirect ophthalmoscopy where a provider uses a handheld ophthalmoscope in one hand that they look through with one eye while using their other hand to use a condensing lens. This variant is called monocular indirect ophthalmoscopy. It doesn’t have the advantage of 3D vision and depth perception, though.

When is this test performed?

Fundoscopy (pronounced "fun-DOSS-ko-pea") is a routine part of medical visits of many kinds. It’s especially common with seeing primary care providers or children’s visits to pediatricians. It can also be part of the following:

Providers can also take this test a step further and do what’s called “extended ophthalmoscopy.” Doing that involves taking a closer view and sketching or drawing what the back of your eye looks like. It’s more common after retinal surgeries or with specific types of retinal conditions.

Test Details

How does fundoscopy work?

The pupil of your eye is actually just a window-like opening. The iris, a ring of muscular tissue around the pupil that gives you your eye color, controls how wide the pupil is. Light entering your eye through your pupil is one of the earliest steps in how your vision works.

Healthcare providers can take advantage of how your eye works by using an ophthalmoscope to look into your eyes. The light on the ophthalmoscope illuminates the inside of your eye, and magnifying lenses give your provider a more detailed view.

When using an ophthalmoscope, your provider is looking for specific things that should be visible at the back of your eye. The things they’re trying to see include your:

What should I expect before fundoscopy?

Fundoscopy usually doesn’t take any preparation on your part (your provider or eye specialist can tell you if there are any exceptions to that).

In some cases, fundoscopy happens after a provider or eye specialist gives you eye drops to dilate your pupils. This is especially common when fundoscopy is part of an eye exam.

What to expect during fundoscopy?

During fundoscopy, a healthcare provider or eye specialist will have you seated in front of them or lying down. This often happens in rooms with dimmed lights to make it easier to see into your eyes. They’ll have you look straight ahead or occasionally have you turn your eyes to look in various directions. If they’re doing indirect ophthalmoscopy, they’ll also hold a handheld lens just in front of your eye. They’ll then align the handheld lens so they can see through it and the viewing window in the ophthalmoscope.

Eye dilation is often part of this test, especially if it’s happening during an eye exam. Dilation lets your provider get a wider view inside your eyes, which can make it easier to see smaller or otherwise hidden issues. They can also tell you about what they’re looking for and what — if anything — they see that might be a cause for concern.

What to expect after the test?

If they see anything that might be a cause for concern, they may also recommend an additional test like fundus photography or a slit lamp exam. It varies, so don’t hesitate to ask your provider or eye specialist more about any tests they recommend and what their concerns might be.

Results and Follow-Up

What do your results mean?

Your provider or eye specialist can tell you what they saw inside your eyes. That includes explaining any potential causes for concern. They can also offer guidance on what you might need to do or understand moving forward.

Some providers may choose to talk you through the process as they’re doing it, giving you a play-by-play description. Other providers may choose to focus on the exam and tell you what they saw in more detail afterward. For the most part, how they tell you is a personal preference. But if you’re anxious or worried, you can tell your provider that before they start doing the fundoscopy exam. They can take your concerns and feelings into account to help reassure you and ease those concerns.

A note from Cleveland Clinic

The eyes are the window to the soul, as the saying goes. But they’re also a window to your health. Medical professionals from many specialties and backgrounds use fundoscopy to look into your eyes and gauge the health of your eyes, brain and body. Fundoscopy (also known as ophthalmoscopy) is one of the most important ways for providers to look into your eyes for important clues or changes that could indicate an issue that needs care.
