Lattice degeneration
Clinically reviewed · Last reviewed 2026-06-13
What it is
Lattice degeneration appears as fine white lines or patches at the edge of the retina where the tissue is thinner. It is not a disease you can feel, but an observation made when the back of the eye is examined.
Symptoms
Lattice degeneration itself causes no symptoms. It matters because it can occasionally predispose to retinal tears.
- Usually no symptoms
- Discovered during dilated eye examination
- Important to report new flashes, floaters or shadows
- More common in short-sighted people
Risk and monitoring
Most people never develop problems. Higher vigilance is sensible if you are very short-sighted, have a family history of retinal detachment, or have had an eye injury. New flashes or a curtain shadow need urgent assessment.
Treatment
No treatment is needed for lattice degeneration alone. If tears develop at its edge, laser or freezing treatment can seal them before detachment occurs. Regular eye checks help catch changes early in high-risk people.
Frequently asked questions
Is lattice degeneration serious?
Usually not. Most people have no problems, but it can increase retinal tear risk in some, especially with high short-sightedness. New flashes or shadows need urgent checks.
Does lattice degeneration need treatment?
The lattice itself does not need treatment. If a retinal tear forms, that tear is treated to prevent detachment.
How is lattice degeneration found?
It is usually seen during a dilated eye examination of the retina, often incidentally in otherwise healthy eyes.
