> **Summary:** A torn retina is a break in the retinal layer that, if untreated, can let the retina separate from the tissue beneath it (retinal detachment) and cause sight loss. Because it is often painless, its signs, such as flashes of light and floaters, must be recognised early.

## Quick Facts
- **Pain:** Usually none
- **Most common sign:** Sudden bursts of light
- **Main treatment:** Retinal laser to seal the tear, under local anaesthetic
- **Return to daily life:** A short while after the procedure

## Signs of a Torn Retina
- A dark area forming in the vision
- Sight that has fallen compared with before
- Floaters in the eye
- Beams or sudden flashes of light

If one or more of these appear, an ophthalmologist should be seen at once. Regular eye examinations help early detection.

## What Is the Retina?
The retina lies at the back of the eye and perceives light. The cornea and lens at the front carry light to it, and the retina passes it to the brain through the optic nerve. The back of the eye is filled with about five millilitres of vitreous gel, with the consistency of egg white, attached to the retina and making up about eighty per cent of the eye's volume. With age the gel breaks down: collagen fibres clump and cause floaters.

## How the Retina Tears
As the hyaluronic acid and collagen of the vitreous break down, the gel separates from the retina, producing bursts of light. If the retina is abnormally attached to the gel, the pull can cause larger tears. Fluid can then pass through the tear and separate the retina from the choroid (the vessel layer that nourishes it), which is retinal detachment. Untreated, this can cause permanent sight loss.

## Causes and Risk Factors
- Age-related deterioration of the vitreous (the most prominent cause).
- Previous cataract surgery, since patients are usually older and gel deformation is more likely.
- Myopia, because the myopic eye is larger than normal.
- Injuries and accidents.
- A family history of retinal tears.

## Diagnosis and Treatment
- A detailed eye examination, then confirmation with devices such as ultrasound.
- The tear's condition and other factors are assessed and a surgical plan made.
- Tears are generally treated with laser; a retinal laser seals the tear, applied the tear in a sterile setting by specialists.
- The procedure is short, under local anaesthetic; patients return to daily activities soon after and should follow the doctor's advice.
