What is Lattice Degeneration?

​Lattice degeneration is a thinning and weakening of the retina — the light-sensitive tissue at the back of the eye that helps you see. It occurs in a crisscross or "lattice" pattern and is most commonly found in the outer edges (peripheral retina) of the eye.

​

Who Gets It?

• Common in nearsighted people (myopia)

• Can be found in about 10% of the general population

• Often develops in both eyes

• May be hereditary (runs in families)

​

Is It Dangerous?

Lattice degeneration by itself usually does not affect vision. However, in some cases, it can increase the risk of:

• Retinal tears

• Retinal detachment (a serious condition that may lead to vision loss)

​

Why Does It Matter?

Because the retina is thin in lattice areas, it may be more vulnerable to:

• Small holes or tears

• Fluid leaking underneath, which can cause a retinal detachment

This is why people with lattice degeneration need regular eye exams, especially if they experience symptoms.

 

Symptoms to Watch For

Most people with lattice degeneration have no symptoms. But seek immediate care if you notice:

• Flashes of light

• New or increased floaters (tiny specks or strings in your vision)

• A shadow or curtain over part of your vision

• Sudden decrease in vision

These can be signs of a retinal tear or detachment, which needs urgent treatment.

 

Diagnosis

Your eye doctor can diagnose lattice degeneration during a dilated eye exam. They may use special lenses and imaging tests to closely examine the retina.

 

Treatment

• No treatment is needed in most cases — just regular monitoring.

• Laser treatment or cryotherapy (freezing) may be recommended if:

  • There’s a retinal tear

  • There’s a high risk of retinal detachment

  • You have symptoms or a family history of detachment

These treatments aim to seal the retina and prevent further problems.

 

Living with Lattice Degeneration

• Most people live their whole lives with no issues.

• Have regular eye exams, especially if you are nearsighted or have a family history of retinal problems.

• Avoid high-impact activities if advised by your eye doctor.

 

When to Call Your Eye Doctor

Seek urgent care if you notice:

• Flashes of light

• Sudden floaters

• Vision loss or changes

• Any visual disturbance that feels new or unusual
