What are floaters?
Floaters are small moving spots, threads, cobweb-like shapes, or shadows that drift across the field of vision. They are often more noticeable when looking at a bright background such as the sky or a white wall.
Many floaters are related to natural changes in the vitreous, the gel-like substance inside the eye. Although they are often harmless, a new change in floaters should still be assessed properly.
What are flashes?
Flashes are brief flickers or streaks of light that may appear in the peripheral vision. They can occur when the vitreous gel pulls on the retina.
Some flashes are related to common vitreous changes, but new or persistent flashes can sometimes indicate traction on the retina and should not be ignored.
Common causes
Floaters and flashes are often caused by age-related vitreous changes, including posterior vitreous detachment. In some cases, however, they may be associated with a retinal tear or retinal detachment.
Because the symptoms can overlap, a comprehensive eye examination is important in order to determine the underlying cause.
When the symptoms may be urgent
Prompt assessment is important if floaters or flashes are:
- new in onset
- suddenly much more numerous
- accompanied by a curtain-like shadow in the vision
- associated with a sudden drop in vision
- present after eye trauma
These features may suggest a retinal tear or retinal detachment and should be evaluated without delay.
Retinal tears and retinal detachment
A retinal tear occurs when traction on the retina creates a break. If fluid passes through that break, the retina can begin to detach.
Because this can threaten vision, warning symptoms such as a sudden increase in floaters, flashes, or a shadow in the field of view should be assessed promptly. More information about retinal assessment and follow-up is available on the Retinal Care & Injections page.
Not all floaters require treatment
Many floaters become less noticeable with time and do not require any intervention. The priority is first to confirm that there is no retinal tear, retinal detachment, or other sight-threatening cause.
Once the eye has been properly examined, patients can usually be advised on what to expect and what warning signs should prompt review.
When to see an ophthalmologist in Paphos
If you notice new floaters, new flashes, or a change in your vision, it is sensible to arrange ophthalmic assessment. You can also read more about urgent eye symptoms on When to See an Eye Doctor or visit the main Ophthalmologist in Paphos page.
