What are eye floaters?
Eye floaters are small specks or cobweb-like shapes that drift across your field of vision. They are especially noticeable when you look at something plain, like a blank wall or blue sky. Eye floaters occur when tiny pieces of the vitreous, the clear, jelly-like substance that fills the inside of your eye, break loose within your eye. These pieces cast shadows on your retina, the light-sensitive layer of tissue at the back of your eye that sends visual signals to your brain, resulting in the appearance of specks or strings drifting through your field of vision.
As we age, the vitreous humor tends to shrink and detach from the retina, causing clumps or strands of connective tissue to become “floating” within the eye. Most eye floaters are caused by age-related changes that occur as the vitreous becomes more liquid. The collagen fibers that make up the vitreous tend to clump and can cast tiny shadows on the retina. These small specks or shapes are called floaters.
What causes eye floaters?
There are a few different causes of eye floaters:
– Age-related vitreous changes: As we get older, the vitreous jelly inside the eyes tends to liquefy and shrink slightly. This allows pieces of debris and protein strands to float freely within the eye. These pieces cast shadows on the retina, appearing as spots or strand-like shapes. Age-related vitreous changes are the most common cause of eye floaters.
– Posterior vitreous detachment: As the vitreous shrinks, it can detach from the retina at the back of the eye. This separation is called a posterior vitreous detachment. It can allow more vitreous debris to float freely within the eye.
– Inflammation: Eye inflammation or injuries may result in debris that causes eye floaters. Inflammation due to uveitis or eye trauma can cause proteins and blood cells to enter the vitreous, casting shadows on the retina.
– Bleeding: Bleeding into the eye, from conditions like diabetic retinopathy, retina tear or detachment can cause blood cell floaters. The blood cells cast shadows on the retina as they break down and float around within the vitreous jelly.
– Deposits in the eye: Fibrous scar tissue due to eye surgery, fatty cholesterol deposits due to high cholesterol, or other types of deposits within the eye can lead to eye floaters.
– Complications from cataract surgery: During cataract surgery, the vitreous may be inadvertently disturbed, causing small fragments of material to float within the eye. These can cast annoying shadows and cause floaters.
Are eye floaters serious?
For the most part, eye floaters are not serious. They are very common, especially as people age. More than half of people over age 60 experience eye floaters due to age-related changes in the vitreous humor.
Most floating spots or strands are harmless specks of vitreous material that do not impair vision or cause complications. However, there are some instances when new onset eye floaters can indicate an underlying problem:
– Sudden increase in eye floaters may signal a posterior vitreous detachment, which can sometimes lead to a retinal tear.
– New floaters along with light flashes can signify a retinal detachment, which should be evaluated immediately.
– Floaters coupled with loss of peripheral vision can indicate retinal detachment or vitreous bleeding.
– Appearance of dark, cobweb-like floaters may indicate bleeding inside the eye, which should be assessed right away.
– People with diabetes may experience new floaters due to bleeding from proliferative diabetic retinopathy.
So while most specks and shapes that appear in your vision are normal age-related changes, it’s a good idea to get your eyes examined if you notice a sudden increase in eye floaters or other vision changes. Retinal tears and detachments require prompt treatment.
Can eye floaters go away or disappear?
In most cases, eye floaters do not completely go away and tend to persist long-term once they appear. This is because the vitreous changes that cause them are permanent. However, there are a few instances in which eye floaters may improve or even disappear.
– Very small specks or strands may fade over time. The tiny shadows they cast may dissipate so they become less bothersome, although usually some floaters remain visible.
– Blood caused eye floaters from hemorrhages often gradually disappear within several weeks to months as the blood is absorbed and cleared from the eye.
– Posterior vitreous detachment floaters may dissipate after some time, sometimes 6-12 months. As the vitreous continues to degenerate, there is less traction on the retina so fewer debris clouds are visible.
– With a vitrectomy surgery, the vitreous is removed and replaced with a saltwater solution. Since most eye floaters originate from the vitreous, their removal eliminates the debris that causes floaters.
It can take time, but the human brain has a remarkable ability to tune out and adapt to the distraction of eye floaters. With time, most people learn to simply ignore the presence of new floaters. However, it takes patience for the brain to adjust to them.
How are eye floaters treated?
1. Eye exams – It’s important to have periodic eye exams by an ophthalmologist. They can rule out any worrisome causes of new onset eye floaters like retinal tears or detachment.
2. Reassurance – For normal age-related floaters, providing reassurance that they are not vision-threatening can give comfort.
3. Adaptation & ignoring floaters – Learning to consciously ignore eye floaters can help the brain learn to filter them out better so they become less bothersome over time.
4. Vitrectomy – This type of eye surgery involves removing the vitreous humor and replacing it with a salt solution. By removing the vitreous, most of the debris that leads to eye floaters is eliminated. However, there are risks with any eye surgery so this option is usually reserved for severe, persistent, disabling floaters.
5. Laser vitreolysis – A YAG laser is used to vaporize large, bothersome vitreous strands or clumps that cause significantly distracting floaters. This less invasive office-based laser procedure can diminish certain large floaters.
6. Atropine – Dilating eye drops like atropine can help temporarily alleviate floaters by dilating the pupil. This seems to minimize the shadows that debris casts on the retina.
7. Nutritional supplements – Although more evidence is needed, some studies suggest supplements like bromelain, vitamin E, and zinc may help relieve certain types of eye floaters. Always check with your doctor before trying new supplements.
8. Hot compresses – Applying warm compresses to the eyes may help temporarily disperse some vitreous clumps and debris, potentially minimizing floaters. However more studies are needed.
9. Reduce stress – Stress and anxiety can make floaters seem more noticeable. Relaxation exercises may lessen the perception of eye floaters.
10. Dark glasses – Wearing certain glasses that have polarized gray lenses can make floaters less visible in bright outdoor light.
Can hot compresses help eye floaters?
Using hot compresses around the eyes may offer some temporary relief from annoying eye floaters caused by vitreous debris. Here’s how it may help:
– Warmth from hot compresses can sometimes loosen up and break apart some clumped vitreous strands within the eye. This can reduce traction on the retina.
– Heat compresses can also create fluid circulation within the eye that may gently disperse some vitreous condensations, minimizing debris clumps.
– The temporary warmth may also slightly expand the eyeball and dilate the pupil, which can diminish the shadows that bits of debris cast on the retina, making floaters less noticeable.
– Applying warm compresses can have a relaxing, therapeutic effect which may reduce overall eye strain and tension. This may make floaters seem subjectively less bothersome.
However, there is limited clinical evidence regarding the effectiveness of hot compresses for treating eye floaters specifically. Some anecdotal reports indicate the following methods may help provide temporary floater relief:
– Soak a clean washcloth in hot water, wring it out, then place the warm washcloth directly over closed eyes for 5-10 minutes.
– Microwave a fabric bag of dry rice for 20-30 seconds to heat it up, then place the warm bag over closed eyes for 5-10 minutes.
– Fill a clean sock with dry white rice, tie off the end, and heat it for 1-2 minutes in the microwave. Apply the heated sock to closed eyes for 5-10 minutes.
– Use an eye/facial mask that can be warmed in the microwave, then apply the warm mask over the eyes for 5-10 minutes.
– Commercially available eye compresses that can be heated up may be used for 5-10 minutes over closed eyes.
It’s important not to make the compress too hot to avoid eye injury or damage. Test your DIY compress on your wrist first to ensure proper temperature. The key is maintaining a comfortably warm, not hot, temperature against the eyelids and surrounding eye area. Discuss trying warm compresses for eye floaters with your eye doctor first to ensure proper technique and safety.
Are hot compresses safe for eye floaters?
When used appropriately, warm compresses can be a safe way to find temporary relief from annoying eye floaters. However, it’s important to keep the following safety precautions in mind when using heat therapy for eye floaters:
– Avoid temperatures that are too hot, which could burn or damage the delicate skin around the eyes. Test any DIY solutions on your wrist first to ensure proper heat.
– Microwave any heat wraps at lower power for short increments to prevent overheating. Check that heated products aren’t too hot before applying.
– Use only clean, hygienic materials to avoid risk of infection around the eyes.
– Apply the warm compress only to closed eyes, never directly on open eyes.
– Limit heat sessions to 5-10 minutes at a time, allowing eyes to rest completely afterwards.
– Discontinue use if any discomfort, pain or vision changes occur.
– Avoid warm compresses if you have any eye injuries, inflammation or conditions affecting the eyes or eyelids.
– Consult your ophthalmologist before trying any at-home remedies like warm compresses for your specific case.
With some simple precautions, warm soaks and compresses can be a beneficial way to find temporary relief from eye floaters. However, they should never replace proper medical treatment if new onset floaters appear suddenly or you experience any concerning vision symptoms. See an eye doctor promptly in these cases.
When to see a doctor about eye floaters
In most instances, normal age-related eye floaters are not a major cause for concern. However, it’s important to see an eye doctor right away if you experience:
– Sudden increase in number and density of new eye floaters
– New floaters along with light flashes in your vision
– Appearance of dark, spiderweb-like floaters
– Floaters accompanied by curtain or veil over any part of your vision
– Any loss of peripheral or side vision
– Persistent floaters that affect your ability to see clearly
– History of injury or trauma to the eye
– Diabetes or history of diabetic retinopathy
– Symptoms of infection like eye pain or redness
– Severe near-sightedness
– Previous cataract surgery
– Younger than age 40 with new onset floaters
Prompt medical evaluation is crucial if any signs of retinal tear or detachment are present, like sudden appearance of dark floaters, light flashes, or loss of visual field. Retinal detachment is a true ophthalmologic emergency requiring urgent treatment.
Conclusion
Eye floaters are very common visual disturbances caused by tiny bits of debris floating in the vitreous humor of the eye. While mostly harmless, new floaters or an increase in them warrants an eye exam to rule out any retinal damage or tears. Though not proven, some people find that applying warm compresses helps temporarily disperse vitreous condensations and minimize eye floaters. When used safely and correctly, warm soaks may provide temporary relief by relaxing the eyes and dispersing some debris. However, floaters treatment ultimately depends on the underlying cause. If new floaters arise, be sure to see your eye doctor promptly for an evaluation, especially if you have any sudden vision changes or loss. With a proper eye assessment and advice from your ophthalmologist, you can determine if simple warm compresses are appropriate for providing temporary relief in your individual case.
