# Retinal tear

[A retinal tear is a small rip in the light-sensitive layer at the back of the eye.](https://bluefinvision.com/blog/what-is-a-retinal-tear-understanding-causes-symptoms-and-treatment/) It can lead to retinal detachment if untreated, so prompt diagnosis and treatment are vital.

## Why retinal tears occur

Most tears happen when the ageing vitreous gel pulls strongly on the retina. This is often linked with posterior vitreous detachment but can also follow trauma.

- Short-sighted eyes are at higher risk because they are longer and the retina is thinner.
- Previous retinal tears or detachments increase the chance of further problems.
- Tears can occur after eye injury or surgery.
- Symptoms include sudden floaters, flashes, or a shower of black spots.
- Some tears cause no symptoms and are found during routine checks.

## Treatment and urgent signs

Sealing a tear early can prevent retinal detachment. Treatment is usually quick and done with laser or freezing therapy under local anaesthetic.

- Laser creates small burns that form a scar around the tear.
- Cryotherapy uses cold to achieve a similar sealing effect.
- Most patients go home the same day and can resume gentle activities soon.
- Seek emergency care if you notice a dark curtain, side vision loss, or sudden blur.
- Regular follow-up monitors for new tears or changes in the other eye.
