What does it mean if you see a white circle in your vision? Most eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous) inside your eyes liquifies and contracts. Scattered clumps of collagen fibers form within the vitreous and can cast tiny shadows on your retina. The shadows you see are called floaters.
What is a Weiss ring? A “Weiss ring” is the circular peripapillary attachment that is visible within the vitreous after it has become detached from the optic nerve head. Figure 3: Optical coherence tomography (OCT) of the macula from a patient who had complete separation of the vitreous (arrowhead) from the fovea center.
What causes Weiss ring? A Weiss Ring floater is a large, ring-shaped floater that forms as a result of PVD when the vitreous cortex pulls off the posterior wall, taking with it some of the fibrous vitreous cortex that surrounds the head of the optic nerve.
Is a Weiss ring serious? While a Weiss ring is usually harmless and will disappear on its own eventually, in a small number of cases a PVD can cause a retinal tear. These are vision threatening and so it is vital to consult with an eye specialist, or an optometrist immediately after developing a Weiss ring.

What are the warning signs of a detached retina?
Detached retina (retinal detachment)
- dots or lines (floaters) suddenly appear in your vision or suddenly increase in number.
- you get flashes of light in your vision.
- you have a dark “curtain” or shadow moving across your vision.
- your vision gets suddenly blurred.
How do you treat a Weiss ring?
Often, Weiss rings can be treated in one session, with larger opaque floaters or amorphous clouds taking multiple treatment sessions with the laser. Limit any treatment to pseudophakic patients to avoid any risk of cataract formation from the abundant amount of laser energy used in the process.
How long does it take for a Weiss ring to disappear?
It is sometimes associated with some flashing lights. The vitreous gel usually then melts or liquefies over the next several weeks to months. The floaters often subside starting within a few days, and all but a few settle to the bottom of the eye and disappear within a 6-month period.
Can vitreous detachment heal itself?
This is a condition where the vitreous, which was gel when the person was younger, has become liquefied and has begun to peel away from the retina. This is a natural development in the majority of people over the age of 60. It doesn’t heal, but it usually doesn’t require any treatment either.
How long does it take for a posterior vitreous detachment to heal?
The posterior vitreous detachment may take 6 to 8 weeks to complete.
What does vitreous detachment look like?
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.
Can stress cause vitreous detachment?
Can stress cause posterior vitreous detachment? As with retinal detachment, stress on its own cannot cause a posterior vitreous detachment (PVD). A PVD is simply a normal process of aging in which the vitreous gel that fills the eye separates from the back of the eye.
How do you fix a vitreous detachment?
If you still have severe floaters after a few months, your doctor may give you the option to use a laser to reduce the floater or have surgery to take out the vitreous gel and clear the floaters. If you have a retina tear, laser surgery or cryopexy, which freezes the tear, can repair it.
Can rubbing eyes cause vitreous detachment?
In general, eye rubbing alone will not lead to retinal tears or detachment. You would have to press and rub your eyes very hard to damage or detach the retina. However, excessive and aggressive eye rubbing is a bad habit that can potentially harm the cornea or cause eye irritation.
How do you check for retinal detachment at home?
Cover one eye. Hold the grid about 10 inches away from the eye you are testing. Look at the center dot keeping your eye focused on it at all times. While looking directly at the center, and only the center, be sure that all the lines are straight and all the small squares are the same size.
Does vitreous gel grow back?
The vitreous body cannot regenerate, so the vitreous cavity must be filled with suitable vitreous substitutes that keep the retina in place and prevent insertion of prosthesis after enucleation of the eye.
How do I keep my vitreous healthy?
Ageing is inevitable, but damage from vitreous deterioration is not. Be sure to consume essential fatty acids, bioflavonoids, amino acids, hyaluronic acid, glucosamine sulfate, silica, vitamin C. Foods that support the vitreous humor include: broccoli.
Can high blood pressure cause vitreous detachment?
High blood pressure can’t directly cause retinal detachment.
How do I restore my vitreous?
Vitrectomy laser surgery can be performed to help alleviate any vitreous floaters. Vitrectomy is a surgical procedure in which the vitreous humor is removed and replaced with another fluid, and a laser is used to repair the retina.
What vitamin deficiency causes floaters in the eyes?
Riboflavin. A riboflavin, or vitamin B-2, deficiency might also increase your risk of seeing spots. Like vitamin C, vitamin B-2 appears to play a role in preventing cataracts, with high levels of riboflavin in your diet helping to prevent cataract development.
Is Omega-3 good for eye floaters?
They found that consumption of omega-3s (≥500 mg/d) significantly reduced the risk of DR. Participants who consumed at least 2 servings of oily fish per week at baseline also had a lower risk of DR. Eye Floaters: Similarly, there’s been promising evidence that supports omega-3 and eye floaters.
