A single small speck drifting across your vision can be distracting, especially against a bright wall, computer screen or Sydney sky. So, are floaters urgent? Often, they are not. However, a sudden shower of new floaters can sometimes be the first warning sign of a tear or detachment in the retina, the light-sensitive tissue at the back of the eye. Knowing the difference can help you protect your sight.
Floaters are common, particularly as we get older, but they should never be dismissed when they appear suddenly or come with other visual changes. A prompt eye assessment can determine whether the cause is harmless or needs urgent treatment.
What eye floaters look like
Floaters may look like tiny dots, squiggly lines, cobwebs, threads or faint shadows that move when your eyes move. They are most noticeable when looking at a pale, evenly lit background. You may try to look directly at one, only to find it drifts away.
They are usually caused by small clumps within the eye’s vitreous, the clear gel that fills the space between the lens and retina. Over time, this gel naturally becomes more liquid and can pull away from the retina. This is called a posterior vitreous detachment, and it is a common age-related change.
For many people, floaters are annoying but harmless. They may become less noticeable as the brain learns to ignore them, even if they do not completely disappear.
Are floaters urgent when they start suddenly?
New floaters need more attention than longstanding, stable floaters. When the vitreous changes or pulls away, it can occasionally tug hard enough on the retina to cause a retinal tear. Fluid may then pass through that tear and lift the retina away from the back of the eye, causing a retinal detachment.
This is why sudden floaters should be assessed as soon as possible, even if they are not painful. Retinal problems are often painless, but time matters because early treatment can help prevent permanent vision loss.
Arrange a same-day urgent eye examination if you notice a sudden increase in floaters, particularly if this is new for you. At Boda Family Eye Care, an urgent assessment can include a thorough examination of the back of the eye to check the retina and identify whether specialist care is needed.
Symptoms that need same-day assessment
Contact an optometrist for urgent advice or seek same-day eye care if you develop new floaters along with flashes of light, especially brief flashes at the edge of your vision. You should also act promptly if you notice a dark curtain, veil or shadow moving across your sight, missing patches of vision, or a clear drop in vision.
A large number of tiny black dots that appear suddenly, sometimes described as pepper, soot or a swarm of insects, can also indicate bleeding inside the eye. This needs assessment without delay.
If an eye injury has occurred, new floaters should be treated as urgent. This includes being hit in the eye, a fall, sport-related trauma or an accident at work. Do not wait to see whether symptoms settle after trauma.
When to attend an emergency department
If you have sudden severe vision loss, a curtain across your vision, significant eye pain, or symptoms after a serious injury, seek emergency medical care immediately. If you cannot access an urgent optometry appointment, attend your nearest emergency department.
For people with new flashes and floaters but no severe loss of vision, an urgent optometrist appointment is often the appropriate first step. An optometrist can examine the retina, explain the findings clearly and arrange a prompt referral to an ophthalmologist if a retinal tear, detachment or another eye condition is suspected.
When floaters can usually wait for a routine appointment
Floaters that have been present for months or years, have not changed, and are not accompanied by flashes, shadows or reduced vision are less likely to be an emergency. It is still sensible to mention them at your next comprehensive eye examination, especially if you have never had them checked.
That said, your own pattern matters. If an old floater changes shape, becomes much more noticeable, or is joined by new symptoms, arrange an appointment sooner. You know what is normal for your vision better than anyone else.
People who are very short-sighted, have had previous eye surgery, have a history of retinal tears or detachment, or have had an eye injury may have a higher risk of retinal problems. Diabetes and inflammation inside the eye can also cause floaters for different reasons. In these situations, it is wise to have a lower threshold for booking an assessment.
What happens at an urgent eye examination?
An urgent eye examination is not simply a check of your glasses prescription. The focus is on finding the cause of the floaters and making sure the retina is healthy.
Your optometrist will ask when the symptoms began, whether they are increasing, and whether you have seen flashes, shadows or vision loss. They will assess your vision and eye pressure, then examine the front and back of your eyes. Drops may be used to dilate the pupils, allowing a much wider and clearer view of the retina.
Dilation can make your vision blurry and light-sensitive for several hours. If possible, bring someone to drive you home, or avoid driving until your vision feels safe and comfortable. Sunglasses can make the trip home more pleasant on a bright day.
If the examination shows a retinal tear or detachment risk, you may be referred urgently to an ophthalmologist. Some retinal tears can be treated with laser therapy to seal the affected area before a detachment develops. The right treatment depends on the finding, which is why timely assessment is so valuable.
Do not rely on a mobile camera or online symptom checker
Floaters cannot usually be assessed safely by looking at an eye in a mirror, taking a photo or comparing symptoms online. The concern is not the floater itself but what may be happening at the back of the eye, where the retina cannot be seen without the right examination equipment.
It is also unhelpful to try eye drops, supplements or exercises as a response to sudden floaters. These will not treat a retinal tear or detachment. While general eye health matters, new warning symptoms call for an examination rather than home treatment.
A clear plan if you notice floaters today
If you have had the same small floaters for a long time with no changes, book a routine comprehensive eye examination if you are due. If the floaters are new, suddenly more numerous, or paired with flashes, a shadow or reduced vision, contact an optometrist for a same-day appointment. If vision loss is sudden or severe, or there has been significant trauma, seek emergency care immediately.
Most floaters do not mean something serious is wrong. The reassuring part is that a careful examination can usually tell the difference, giving you either peace of mind or the prompt care needed to protect your vision.
