Quick Answer: You should see a retina specialist for new, sudden, or significantly increased floaters, especially if they occur with flashes of light, a shadow or curtain in your vision, or sudden vision loss. While many floaters are harmless and related to normal changes in the eye’s vitreous gel, a sudden increase in floaters can be a warning sign of a retinal tear or retinal detachment that requires prompt evaluation.

What Are Eye Floaters?

Eye floaters are spots, specks, lines, or web-like shapes that appear to drift across your vision. They are caused by small clumps or changes within the vitreous, the gel-like substance that fills the inside of the eye.

Floaters may be most noticeable when looking at a bright background, such as a clear sky, white wall, or computer screen. Many floaters are harmless, particularly when they have been present for a long time and have not changed.

However, new or suddenly increasing floaters are different and deserve attention.

When Are Floaters a Warning Sign?

Sudden floaters can happen when the gel inside your eye naturally pulls away from the retina, a common age-related change called a posterior vitreous detachment (PVD). Most of the time, this isn’t serious. However, sometimes the pulling can cause a tear in the retina, which needs prompt treatment.

A retinal tear can progress to a retinal detachment, which may cause permanent vision loss without prompt treatment.

Seek urgent evaluation if you notice:

• • A sudden increase or “shower” of new floaters
  • New flashes of light
  • A dark curtain or shadow across your vision
  • Sudden loss of peripheral vision
  • A new area of missing or distorted vision
  • Sudden vision loss

Do not wait for these symptoms to go away on their own. A dilated retinal examination can help determine whether a retinal tear or other retinal problem is present.

Do Floaters Always Mean Something Is Wrong With the Retina?

No. Floaters are common and often become more noticeable with age as the vitreous naturally changes.

They may also occur with:

• • Posterior vitreous detachment
  • Aging-related changes in the vitreous
  • Nearsightedness
  • Previous eye surgery
  • Eye inflammation
  • Bleeding inside the eye
  • Retinal tears or detachment

Since several different conditions can cause floaters, the appearance and timing of your symptoms matter. A retina specialist can determine whether the floaters are related to a normal vitreous change or something requiring treatment.

Should I See a Retina Specialist for New Floaters?

Yes, particularly when floaters appear suddenly or are accompanied by flashes or other vision changes.

A retina specialist has specialized training in diagnosing conditions affecting the retina and vitreous. During an evaluation, the specialist can examine the peripheral retina for tears, holes, detachment, bleeding, inflammation, or other abnormalities. This is especially important when symptoms develop quickly. Learn more about MERSI’s retina care and specialist expertise near Boston.

What Happens During an Evaluation for Floaters?

A retina evaluation typically begins with a detailed eye examination and may include dilation to allow the specialist to examine the retina thoroughly.

Depending on your symptoms, testing may include:

• • Dilated retinal examination
  • Optical Coherence Tomography (OCT)
  • Retinal photography
  • Wide-field retinal imaging
  • Other specialized diagnostic testing when appropriate

The goal is to identify the cause of the floaters and determine whether treatment or monitoring is needed.

Can a Retina Tear Cause Floaters?

Yes. A retinal tear can cause a sudden increase in floaters, often along with flashes of light.

A tear can happen when the vitreous, pulls on the retina. If the tear allows fluid to get underneath the retina, the retina can begin to separate from the back of the eye. This is called a retinal detachment and can threaten vision.

Since a retinal tear can sometimes be treated before it leads to a retinal detachment, sudden new floaters should be evaluated promptly by an eye specialist.

What If I Have Had Floaters for Years?

Long-standing floaters that have remained stable are often less concerning than floaters that appear suddenly or change significantly.

Even so, if an existing floater suddenly becomes more prominent, you develop additional floaters, or you notice flashes or changes in your vision, you should contact an eye specialist promptly.

When Should I See a Retina Specialist for Floaters?

Consider prompt retinal evaluation if you experience:

• • New floaters that appear suddenly
  • A sudden increase in the number of floaters
  • Floaters accompanied by flashes
  • A shadow or curtain in your vision
  • Sudden loss of peripheral vision
  • Any sudden or unexplained vision loss

These symptoms can sometimes indicate a retinal tear or detachment. Early evaluation gives a specialist the opportunity to identify problems before they cause permanent vision loss.

Get Your Floaters Evaluated at MERSI

New or suddenly increasing floaters shouldn’t be ignored. MERSI’s fellowship-trained retina specialists use comprehensive retinal examinations and advanced imaging to determine whether floaters are related to normal vitreous changes or a condition requiring treatment.

If you’ve noticed sudden floaters, flashes, or other unexpected changes in your vision, contact MERSI to schedule a retinal evaluation at our Waltham location, conveniently serving patients from Brookline and surrounding Boston communities.

Frequently Asked Questions About Floaters

Are eye floaters usually harmless?

Many floaters are harmless and result from normal age-related changes in the vitreous. However, new or suddenly increasing floaters can sometimes signal a retinal tear or other serious condition and should be evaluated promptly.

How many floaters are too many?

There is no specific number that is considered too many. A sudden “shower” or dramatic increase in floaters is more concerning than a few stable floaters that have been present for years.

Are floaters and flashes related?

They can be. When the vitreous pulls on the retina, it can cause both floaters and flashes. New flashes accompanied by a sudden increase in floaters should receive prompt retinal evaluation.

Can floaters cause blindness?

Floaters themselves usually do not cause blindness. However, the condition causing sudden floaters (such as a retinal tear, retinal detachment, or bleeding inside the eye) can threaten vision if not treated appropriately.

Should I go to the emergency room for sudden floaters?

Sudden floaters, particularly when accompanied by flashes, a curtain-like shadow, peripheral vision loss, or sudden vision loss, require immediate evaluation. Contact an eye specialist or seek emergency eye care rather than waiting for a routine appointment.
