Observation
When the retina is intact and floaters are uncomplicated, monitoring and clear return precautions are common.
Symptom guide
Eye floaters & flashes
Most floaters are related to changes in the vitreous, but a sudden increase can be a warning sign of a retinal tear or detachment.
Sudden change? Arrange urgent retinal examination
Seek urgent in-person eye care for many new floaters, repeated flashes, a curtain or shadow, loss of side vision, sudden blur or symptoms after injury.
Understanding the concern
A clear diagnosis comes before a treatment plan
Floaters can look like dots, cobwebs, strands or rings moving across the vision. Flashes may look like brief streaks of light. They often occur as the vitreous gel changes and separates from the retina with age.
A symptom description cannot rule out a retinal tear. New or suddenly increased floaters and flashes need a dilated retinal examination, especially when accompanied by a shadow or reduced vision.
What patients notice
Describe what you are seeing
These features can overlap with other eye conditions. Examination is needed to establish the cause.
- New dots, strands, rings or cobwebs
- A sudden shower of small dark spots
- Brief flashes at the edge of vision
- Haze or a moving dark patch
- A fixed shadow or curtain
- Symptoms after trauma or eye surgery
Specialist assessment
What the consultation may involve
The goal is to identify the cause and, most importantly, exclude a retinal tear, bleeding or detachment.
01
Dilated retinal examination
The peripheral retina is examined carefully for tears, holes, detachment, pigment or bleeding.
02
Vitreous examination
The vitreous is assessed for posterior vitreous detachment, inflammation, blood and other opacities.
03
Ultrasound when needed
If blood or another opacity blocks the retinal view, ocular ultrasound may provide additional information.
Treatment planning
Treatment depends on the cause
Many uncomplicated floaters become less intrusive with time. Retinal tears, bleeding, inflammation or detachment require cause-specific care.
Laser or cryotherapy for a tear
A retinal tear may be sealed to reduce the risk of fluid passing underneath and causing detachment.
Treat the underlying condition
Inflammation, vitreous haemorrhage and retinal detachment are managed according to their specific cause and severity.
From first assessment to follow-up
- 01Note whether symptoms are new, sudden or increasing
- 02Seek urgent examination when warning signs are present
- 03Dilate the pupil and examine the peripheral retina
- 04Treat a tear or other cause if found
- 05Follow return precautions for any new shadow, blur or increase in symptoms

Checking new floaters and flashes safely
As a vitreoretinal specialist, Prof. Amer Awan evaluates floaters in the context of posterior vitreous detachment, retinal tears, bleeding and retinal detachment rather than treating the symptom in isolation.

Questions patients ask
About Floaters & flashes
Are all floaters dangerous?
No. Many are harmless, but the appearance alone cannot reliably exclude a retinal tear. Sudden onset or increase warrants an urgent dilated retinal examination.
Can a phone photo or online chat rule out a tear?
No. A dilated retinal examination is needed to assess the peripheral retina.
Do floaters go away?
They may become less noticeable as they move or the brain adapts, but some persist. Management depends on cause and visual impact.
