Eye Floaters: Causes, Symptoms, and Treatment

What kind of doctor treats Eye Floaters?
An ophthalmologist, an eye doctor who is a medical doctor, usually checks eye floaters. Your eye doctor can check for floaters as part of a dilated eye exam. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What are eye floaters?
Floaters are small dark shapes that float across your vision. They can look like spots, threads, squiggly lines, or even little cobwebs.
The specks are not on the surface of your eyes but inside them. They are bits of cell debris that drift around in the fluid, called the vitreous, in the back of your eye. Most adults have at least a few floaters.
Most of the time floaters are harmless.
Symptoms
Floaters move as your eyes move. When you try to look at them directly, they seem to move away. When your eyes stop moving, floaters keep drifting across your vision.
You may notice floaters more when you look at something bright, like white paper or a blue sky. They can also be more visible when you are reading, especially if the floater is dense or dark.
Most people have floaters that come and go.
Causes and who gets it
Floaters usually happen because of normal changes in your eyes. As you age, tiny strands of the vitreous, the gel-like fluid that fills your eye, stick together. They cast shadows on the retina, the light-sensitive layer of tissue at the back of the eye. Those shadows appear as floaters.
Almost everyone develops floaters as they get older. You are at higher risk if you:
- Are very nearsighted.
- Have diabetes.
- Have had surgery to treat cataracts.
Sometimes floaters have more serious causes, including:
- Eye infections.
- Eye injuries.
- Uveitis, which is inflammation in the eye.
- Bleeding in the eye.
- Vitreous detachment, when the vitreous pulls away from the retina.
- A retinal tear, when vitreous detachment tears a hole in the retina.
- Retinal detachment, when the retina gets pulled away from the back of the eye.
How doctors diagnose it
Your eye doctor can check for floaters as part of a dilated eye exam. The doctor gives you eye drops to dilate, or widen, your pupil. Then the doctor checks your eyes for floaters 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.
Treatment
Treatment depends on the cause. If another eye condition causes your floaters, you may need treatment for that condition. If aging causes them and they do not bother you, you probably will not need treatment.
It is difficult to eliminate floaters. If floaters make it hard to see clearly and get in the way of daily life, your eye doctor might suggest a surgery called a vitrectomy. A vitrectomy is a major eye operation, and many doctors feel it is too risky for a minor problem such as floaters. Talk with your doctor about the risks and benefits.
A laser treatment called YAG can break up floaters and possibly make them less visible, but it does not really remove them. Atropine eye drops can make floaters less visible, but they may cause blurred vision. Some homeopathic eye drops are sold for floaters, but they have not been shown to have proven benefit.
When to see a doctor
Go to your eye doctor or the emergency room right away if you notice signs of a retinal tear or retinal detachment, such as:
- A lot of new floaters that appear suddenly, sometimes with flashes of light.
- A dark shadow, like a curtain, or a blurry area in your side or central vision.
Retinal tear or detachment can be a medical emergency. Retinal detachment can cause permanent vision loss, but getting treatment right away can help protect your vision.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A direct primary care doctor can talk through your symptoms and help you get an eye exam. They can also refer you to an eye doctor.
Common questions
Are eye floaters dangerous?
Most of the time, floaters are harmless. But sometimes floaters can be a sign of a more serious eye condition. A sudden increase in floaters, or floaters with flashes of light, may be a sign of a retinal tear or detachment.
Do eye floaters need treatment?
Often they do not. If aging causes your floaters and they do not bother you, you probably will not need any treatment. If another eye condition causes them, that condition may need treatment.
When are eye floaters an emergency?
They can be an emergency when they come with signs of a retinal tear or detachment. These signs include a lot of new floaters that appear suddenly, sometimes with flashes of light. They also include a dark shadow or curtain over part of your vision. Go to your eye doctor or the emergency room right away.
Does everyone get eye floaters?
Almost everyone gets them as they get older. Seeing a few floaters is normal. You are at higher risk if you are very nearsighted, have diabetes, or have had cataract surgery.
