Condition
Retinal tear
Clinically reviewed · Last reviewed 2026-06-13
What it is
As the vitreous gel shrinks it can tug on the retina, creating a tear. Fluid may then pass through the tear, lifting the retina off — retinal detachment.
Warning symptoms
Treat these as urgent.
- Sudden new flashes of light
- A sudden shower of floaters
- A shadow or curtain spreading across vision
- Symptoms after eye injury or in very short-sighted people
Risk factors
High short-sightedness, previous eye surgery, injury, lattice degeneration and family history of detachment increase risk. Posterior vitreous detachment is a common trigger in older adults.
Treatment
Laser or cryotherapy around the tear creates a scar barrier that prevents detachment. When caught early, treatment is quick and often done in clinic. A spreading shadow suggests detachment and needs emergency surgery.

Frequently asked questions
Is a retinal tear an emergency?
Yes. New flashes, floaters or a shadow need same-day eye assessment. Early laser treatment can prevent retinal detachment.
What is the difference between a retinal tear and detachment?
A tear is a split in the retina; detachment is when the retina lifts away. A tear can be sealed before detachment occurs if treated promptly.
How is a retinal tear treated?
Laser or freezing treatment around the tear seals the retina and greatly reduces detachment risk. It is usually done promptly in clinic or hospital.
