What is lattice degeneration?
Lattice degeneration is a thinning and weakening of the peripheral retina (the outer edges of the retina at the back of the eye). It is a common condition, affecting about 7–10% of the general population. While lattice degeneration itself usually does not cause symptoms or vision loss, it can increase the risk of retinal tears or retinal detachment, which are serious conditions that can threaten vision.
Causes and risk factors
- Genetics: Lattice degeneration often runs in families.
- High myopia (nearsightedness): People with moderate to high myopia are at increased risk.
- Age: Most commonly detected in teens and young adults, but can be found at any age.
- Previous retinal detachment: Increases the risk in the other eye.
- Other eye conditions: Certain inherited retinal diseases may be associated with lattice degeneration.
Symptoms
Lattice degeneration itself usually does not cause symptoms. However, if a retinal tear or detachment develops, you may notice:
- Sudden increase in floaters (small spots or cobwebs in your vision)
- Flashes of light
- A shadow or curtain over part of your vision
- Sudden decrease in vision
If you experience any of these symptoms, seek prompt evaluation.
Diagnosis
Diagnosis is made during a comprehensive dilated eye exam:
- Dilated retinal exam: The ophthalmologist uses special lenses to examine the peripheral retina for areas of thinning, holes, or tears.
- Imaging (if needed): Optical coherence tomography (OCT) or widefield retinal imaging may be used to document findings.
Treatment options
- Observation: Most cases of lattice degeneration do not require treatment and are simply monitored with regular eye exams.
- Laser treatment (retinal photocoagulation): If there are associated retinal tears, holes, or if you are at high risk for retinal detachment, laser treatment may be recommended to seal the retina and prevent detachment.
- Surgical intervention: Rarely needed unless a retinal detachment occurs, in which case prompt surgery is required.
Prognosis and ongoing care
- Most people with lattice degeneration never develop complications and maintain normal vision.
- Regular eye exams are important to monitor for changes, especially if you are nearsighted or have a family history of retinal detachment.
- Early detection and treatment of retinal tears or detachment can prevent permanent vision loss.
