Floaters — the difference between routine and retinal emergency
Floaters are the little specks, threads or cobwebs that drift across your vision. Most are harmless age-related changes in the vitreous gel — but a sudden shower of new floaters, especially with flashes of light, is a red flag for a retinal tear.
What can cause this — and how each feels different.
Age-related vitreous degeneration
The vitreous gel liquefies with age; the resulting strands cast shadows on the retina. Common after 50, painless, gradual.
Posterior vitreous detachment (PVD)
The vitreous suddenly pulls away from the retina — often causing new floaters with brief flashes. Needs a dilated retina check to rule out a tear.
Retinal tear or detachment
Emergency. A sudden shower of new floaters + flashes + a shadow / curtain in the vision needs same-day retinal surgery.
Vitreous haemorrhage
Blood in the vitreous, often in a diabetic patient — reduced vision, red-tinged floaters.
Uveitis
Inflammatory cells create hazy 'snow-globe' floaters with a red painful eye.

Questions patients ask us most.
Do floaters go away on their own?
The floaters usually stay but the brain learns to ignore them over 3-6 months. Rarely, floaters that block central vision may benefit from a vitrectomy.
Are floaters common after cataract surgery?
Yes — cataract surgery can trigger a posterior vitreous detachment, which is why we advise a follow-up retina check if new floaters appear post-op.
Can floaters cause blindness?
Floaters themselves do not. But the retinal tear that some floaters warn of can — which is why sudden new floaters always need a dilated retina examination.
