What is vitreous detachment?

The vitreous is the gel-like fluid that fills your eye. It’s full of tiny fibers that attach to your retina (the light-sensitive layer of tissue at the back of the eye).

As you get older, the fibers of your vitreous pull away from the retina. This is called vitreous detachment. It usually happens after age 50. You may not notice when your vitreous detaches — or you may notice symptoms that affect your vision.

If you notice symptoms of vitreous detachment, talk to your eye doctor.

What are the symptoms of vitreous detachment?

The most common symptom of vitreous detachment is a sudden increase in floaters (small dark spots or squiggly lines that float across your vision). When your vitreous detaches, strands of the vitreous often cast new shadows on your retina — and those shadows appear as floaters.

You may also notice flashes of light in your side (peripheral) vision.

Sometimes, vitreous detachment causes more serious eye problems that need treatment right away. The only way to tell if vitreous detachment has caused a serious eye problem is to get a dilated eye exam. So if you notice symptoms of vitreous detachment, it’s important to go to your eye doctor right away.

If your vitreous detachment doesn’t cause a serious eye problem, you’ll probably stop noticing symptoms as much after a few months.

What other problems can vitreous detachment cause?

Vitreous detachment can sometimes lead to more serious eye conditions:

• Retinal tear. Sometimes, the vitreous fibers tear a hole in the retina when they pull away. If you don’t get treatment quickly, this can lead to retinal detachment.
• Retinal detachment. Sometimes vitreous detachment pulls the entire retina away from its normal position at the back of the eye. This can be a medical emergency. Learn more about retinal detachment.
• Macular hole. Sometimes vitreous detachment tears a hole in the macula (the part of the retina that controls your central vision). This can happen before or after the vitreous detaches enough to cause floaters or flashes of light. Learn more about macular hole.
• Macular pucker. Sometimes vitreous detachment causes a thin layer of scar tissue to grow over the macula. This usually happens slowly in the months or years after vitreous detachment. Learn more about macular pucker.

These conditions can cause vision loss — but treatment may help preserve your vision. Tell your eye doctor right away if you notice symptoms of vitreous detachment so they can check for these more serious problems.

Am I at risk for vitreous detachment?

If you’re age 50 or older, you’re at risk for vitreous detachment — and your risk increases as you age. Vitreous detachment is very common in people over age 80. You’re also at higher risk if you’re nearsighted.

If you have vitreous detachment in 1 eye, you’re at higher risk of getting it in the other eye.

How will my eye doctor check for vitreous detachment?

Eye doctors can check for vitreous detachment as part of a dilated eye exam. Your doctor will give you some eye drops to dilate (widen) your pupil and then check your eyes for vitreous detachment and other eye problems.

This exam is usually painless. The doctor may press on your eyelids to check for retinal tears, which may be uncomfortable for some people.

What’s the treatment for vitreous detachment?

If your vitreous detachment doesn’t cause a more serious eye condition, you probably won’t need any treatment. If your vitreous detachment causes a serious condition — like a retinal tear — you may need treatment for that condition.

If your floaters still bother you after a few months and make it hard to see clearly, your eye doctor might suggest a surgery called a vitrectomy to remove them. Talk with your doctor about the risks and benefits of this surgery.

Your eye care provider will discuss treatment options with you. You may need a combination of treatments for the best results.

Treatments include:

• Laser therapy or cryopexy.
• Pneumatic (gas bubble) retinopexy.
• Scleral buckle.
• Vitrectomy.

Laser (thermal) therapy or cryopexy (freezing)

Sometimes, your provider will diagnose a retinal tear before the retina starts pulling away. Your provider uses a medical laser or a freezing tool to seal the tear. These devices create a scar that holds the retina in place.

Pneumatic retinopexy

Your provider may recommend this approach for the right candidates. During pneumatic retinopexy:

1. Your provider injects a small gas bubble into the eye.
2. The bubble presses against the retina, closing the tear.
3. You may need laser or cryopexy (freezing) to seal the tear.
4. Your body reabsorbs the fluid that collected under your retina. Your retina can now stick to your eye wall the way that it should. Eventually, your body also absorbs the gas bubble.

After surgery, your provider will recommend that you keep your head still for a few days to promote healing. Your provider may also tell you what position you should lie in or sleep in.

These recommendations may seem uncomfortable or annoying, but they’re particularly important. It’s a short-term sacrifice for long-term benefits.

Scleral buckle

During a scleral buckle surgery:

1. Your provider surgically places a silicone band or sponge (buckle) around the eye.
2. The band holds the retina in place and stays there permanently. You can’t see the band.
3. Your provider seals the tear with a laser or cryopexy.
4. Your provider may inject a gas bubble or drain the fluid under the retina to help reattach it.

Vitrectomy

During a vitrectomy, your provider:

1. Surgically removes the vitreous.
2. Uses laser or freezing to seal all retinal tears or holes.
3. Places a bubble of air, gas or oil in the eye to push the retina back in place.

If your provider uses an oil bubble, you’ll have it removed a few months later. Your body reabsorbs gas and air bubbles. If you have a gas bubble, you may have to avoid activities at certain altitudes. The altitude change can increase the size of the gas bubble and the pressure in your eye. You’ll have to avoid flying and traveling to high altitudes. Your provider will tell you when you can start these activities again.

Complications/side effects of treating retinal detachment

While surgery to reattach your retina is often very successful, any surgery can have risks or complications. These risks and complications include:

• Bleeding.
• Infection.
• Higher pressure in your eye (intraocular pressure).
• The chance that you may need another surgery.
• Membranes that form after surgery that can shrink and pull tissues out of place. The name for this is proliferative retinopathy or epiretinal membrane.
• Rapid cataract formation that requires additional cataract surgery.

What can I expect after retinal detachment surgery?

After treatment for a detached retina, you may have some discomfort. It can last for a few weeks. Your provider will discuss pain medicine and other forms of relief. You’ll also need to take it easy for a few weeks. Talk with your provider about when you can exercise, drive and get back to your regular activities.

What does a scar on the left eye mean?

These scars can be caused by improper use of contact lenses, deep scratches, lacerations, burns, and some diseases like shingles and syphilis. After major damage, clear corneal tissue may be replaced by scar tissue or become occluded by new blood vessels (a problem called neovascularization).

What is the scar that goes through your eye?

A corneal scar blocks or distorts light as it enters the eye and can lead to decreased vision. Corneal scars are most commonly caused by an infection, injury or disease; however, procedures such as an eyelash lift and laser eye surgery also pose a slight risk. The cornea is the clear front surface of the eye.

What does a corneal scar look like?

They look like a white opacity in the normally clear cornea. Sometimes, corneal scars are visible to the naked eye. Some types of scars are more difficult to detect. Scars that change the shape of the cornea, making the surface more irregular, may not be apparent to your doctor with a routine exam.

What are the early warning signs of a detached retina?

Symptoms.

The sudden appearance of many floaters — tiny specks that seem to drift through your field of vision..

Flashes of light in one or both eyes (photopsia).

Blurred vision..

Gradually reduced side (peripheral) vision..

A curtain-like shadow over your field of vision..
