Eye floaters are small, dark spots or lines that drift across your field of vision. They're usually caused by tiny pieces of debris floating in the vitreous humor, the gel-like substance that fills the back of your eye.
Eye floaters are very common, and most people will experience them at some point in their lives. They're usually not a sign of a serious problem, but they can be a nuisance.
In this article, we'll discuss the causes of eye floaters, how to get rid of them, and when to see a doctor.
what causes eye floaters
Eye floaters are small, dark spots or lines that drift across your field of vision. They're usually caused by tiny pieces of debris floating in the vitreous humor, the gel-like substance that fills the back of your eye.
- Aging
- Posterior vitreous detachment
- Eye inflammation
- Bleeding in the eye
- Retinal tears
- Eye surgery
- Diabetes
- High blood pressure
- Certain medications
In most cases, eye floaters are not a sign of a serious problem. However, they can be a nuisance and may interfere with your vision. If you're concerned about eye floaters, talk to your doctor.
Aging
As we age, the vitreous humor, the gel-like substance that fills the back of the eye, begins to shrink and liquefy. This process, called posterior vitreous detachment (PVD), is a common cause of eye floaters. During PVD, tiny pieces of debris in the vitreous humor can break loose and float around in the eye, causing floaters.
- Shrinking vitreous humor:
As we age, the vitreous humor loses volume and becomes more liquid. This can cause it to pull away from the retina, the light-sensitive tissue at the back of the eye. This process is called posterior vitreous detachment (PVD).
- Detachment of the vitreous humor:
PVD can cause the vitreous humor to detach from the retina. This can cause a sudden increase in the number of floaters you see.
- Bleeding in the eye:
PVD can also cause bleeding in the eye. This can lead to the formation of blood floaters.
- Retinal tears:
PVD can also cause retinal tears. Retinal tears are small breaks in the retina. They can lead to more serious problems, such as retinal detachment.
If you are experiencing a sudden increase in the number of floaters you see, or if you see floaters that are accompanied by other symptoms, such as flashes of light or blurred vision, it is important to see a doctor right away.
Posterior vitreous detachment
Posterior vitreous detachment (PVD) is the most common cause of eye floaters. It is a condition in which the vitreous humor, the gel-like substance that fills the back of the eye, separates from the retina, the light-sensitive tissue at the back of the eye. This can cause tiny pieces of debris in the vitreous humor to break loose and float around in the eye, causing floaters.
- Age-related changes:
PVD is most common in people over the age of 50. This is because the vitreous humor becomes more liquid and less viscous as we age, making it more likely to detach from the retina.
- Eye trauma:
PVD can also be caused by eye trauma, such as a blow to the head or a penetrating eye injury.
- Certain medical conditions:
PVD is more likely to occur in people with certain medical conditions, such as diabetes, high blood pressure, and sickle cell anemia.
- Eye surgery:
PVD can also be a complication of eye surgery, such as cataract surgery or retinal detachment surgery.
PVD is usually not a serious condition. However, it can sometimes lead to more serious problems, such as retinal tears and retinal detachment. If you experience a sudden increase in the number of floaters you see, or if you see floaters that are accompanied by other symptoms, such as flashes of light or blurred vision, it is important to see a doctor right away.
Eye inflammation
Eye inflammation, also known as uveitis, can cause eye floaters. Uveitis is a condition in which the uvea, the middle layer of the eye, becomes inflamed. The uvea contains the iris, the colored part of the eye, the ciliary body, which produces the fluid that fills the eye, and the choroid, which supplies blood to the retina.
There are many different causes of uveitis, including:
- Infections, such as toxoplasmosis, herpes simplex virus, and cytomegalovirus
- Autoimmune diseases, such as rheumatoid arthritis, lupus, and Crohn's disease
- Eye injuries
- Certain medications
- Cancer
Uveitis can cause a variety of symptoms, including:
- Eye pain
- Redness
- Blurred vision
- Floaters
- Sensitivity to light
If you experience any of these symptoms, it is important to see a doctor right away. Uveitis can lead to serious complications, such as glaucoma, cataracts, and retinal detachment, if it is not treated.
Treatment for uveitis depends on the underlying cause. Treatment may include:
- Anti-inflammatory medications
- Antibiotics or antiviral medications
- Immunosuppressive medications
- Surgery
Bleeding in the eye
Bleeding in the eye, also known as vitreous hemorrhage, can cause eye floaters. Vitreous hemorrhage occurs when blood vessels in the vitreous humor, the gel-like substance that fills the back of the eye, break and leak blood into the vitreous humor.
There are many different causes of vitreous hemorrhage, including:
- Posterior vitreous detachment (PVD)
- Retinal tears
- Retinal detachment
- Eye injuries
- Eye surgery
- Certain medical conditions, such as diabetes and high blood pressure
- Blood clotting disorders
- Cancer
Vitreous hemorrhage can cause a variety of symptoms, including:
- Sudden onset of floaters
- Blurred vision
- Redness
- Pain
- Loss of vision
If you experience any of these symptoms, it is important to see a doctor right away. Vitreous hemorrhage can lead to serious complications, such as glaucoma, cataracts, and retinal detachment, if it is not treated.
Treatment for vitreous hemorrhage depends on the underlying cause and the severity of the bleeding. Treatment may include:
- Observation
- Laser surgery
- Vitrectomy (surgery to remove the vitreous humor)
Retinal tears
A retinal tear is a small break in the retina, the light-sensitive tissue at the back of the eye. Retinal tears can be caused by a variety of factors, including:
- Posterior vitreous detachment (PVD)
- Eye injuries
- Lattice degeneration (a weakening of the retina)
- Retinal detachment surgery
- Certain medical conditions, such as diabetes and high blood pressure
Retinal tears can cause a variety of symptoms, including:
- Sudden onset of floaters
- Flashes of light
- Blurred vision
- A curtain-like shadow over part of your vision
If you experience any of these symptoms, it is important to see a doctor right away. Retinal tears can lead to retinal detachment, a serious condition that can cause permanent vision loss if it is not treated.
Treatment for retinal tears depends on the size and location of the tear. Treatment may include:
- Laser surgery
- Cryopexy (freezing the retina around the tear)
- Scleral buckle (a surgical procedure to support the retina)
- Vitrectomy (surgery to remove the vitreous humor)
Early diagnosis and treatment of retinal tears can help to prevent retinal detachment and preserve vision.
Eye surgery
Eye surgery can sometimes cause eye floaters. This is because eye surgery can damage the vitreous humor, the gel-like substance that fills the back of the eye. When the vitreous humor is damaged, it can release tiny pieces of debris that can float around in the eye, causing floaters.
Eye surgeries that can cause floaters include:
- Cataract surgery
- Glaucoma surgery
- Retinal detachment surgery
- Vitrectomy (surgery to remove the vitreous humor)
The risk of developing eye floaters after eye surgery is generally low. However, the risk is higher if you have a history of eye floaters, if you are over the age of 50, or if you have certain medical conditions, such as diabetes or high blood pressure.
If you experience eye floaters after eye surgery, it is important to see your doctor right away. In most cases, the floaters will go away on their own within a few weeks or months. However, in some cases, the floaters may be permanent.
If you are concerned about the risk of developing eye floaters after eye surgery, talk to your doctor before the surgery. Your doctor can discuss the risks and benefits of the surgery and help you decide if the surgery is right for you.
Diabetes
Diabetes is a chronic disease that affects how your body turns food into energy. There are two main types of diabetes: type 1 and type 2. Both types of diabetes can lead to eye problems, including eye floaters.
How diabetes can cause eye floaters
