Eye floaters are very common, especially as people age.
Did you know…?
70%
of people over 60 experience eye floaters at some point. However, in a small percentage of cases, floaters can signal a more serious issue such as a retinal tear or detachment.
1 in 10
people who suddenly develop new floaters (especially with flashes of light or loss of peripheral vision) may have a retinal tear.
30-50%
Of those with a retinal tear, 30-50% can progress to a retinal detachment if not treated promptly.
Early diagnosis and treatment can make a life-changing difference in preserving vision, especially in cases of retinal detachment.
One of the most critical factors influencing visual outcomes is the time between the onset of symptoms and surgical intervention. When the detachment does not involve the central part of the retina (the macula), surgical results are typically positive. However, once the detachment extends to the macula, the area responsible for sharp, central vision, even successful surgery may not fully restore sight.
This occurs because the retina is part of the brain’s delicate nervous tissue. When it detaches, the connection between the retina and its underlying support layer is disrupted. Although surgery can reattach the retina, the microscopic connections rarely return to their original state.
Recognising symptoms early and seeking immediate medical attention is therefore essential to protect vision.
Key Symptoms of Retinal Detachment
Two main warning signs should prompt an urgent consultation with an ophthalmologist:
- A dark curtain, shadow, or veil moving across vision
- Blurred or distorted vision
- Loss of peripheral vision
- Central vision loss if the macula becomes involved
If you notice any of these symptoms, book a consultation with one of our consultant ophthalmologists:
When to See an Ophthalmologist
Not all floaters or flashes indicate retinal detachment, but they should never be ignored. A comprehensive eye examination, including a detailed retinal (fundus) assessment, is essential to determine the cause.
In some cases, symptoms may result from a natural, age-related process known as posterior vitreous detachment (PVD). In others, they may signal a retinal tear or detachment requiring urgent treatment to prevent permanent vision loss.
In Summary
Early evaluation saves vision.
If new floaters, flashes of light, or sudden changes in vision occur, seek an ophthalmological assessment without delay.
Vision is precious, and timely action can make all the difference.
