Lattice Degeneration
-
What it is: Lattice degeneration is a peripheral retinal change seen on exam in which certain areas of the retina become thin, white, and crisscrossed in a lattice-like pattern. These areas may also develop small atrophic holes. It is a common degenerative finding in the retina and is usually discovered during routine dilated eye exams.
-
Who it affects: It can occur in many people and is more likely in individuals with myopia (nearsightedness). Lattice changes may be found in one or both eyes.
-
Symptoms:
-
Most people with lattice degeneration do not have any symptoms. However, if the retina develops a tear or a retinal detachment in the area of the lattice, symptoms may include:
-
Flashes of light
-
New floaters
-
A shadow or curtain in peripheral vision
-
-
Treatments:
-
Lattice degeneration itself usually does not require treatment if it’s stable and without tears. However, if associated with retinal holes or early detachment, treatment such as laser retinopexy may be recommended to help “wall off” the area and reduce risk of retinal detachment.

Frequently Asked Questions
Q: What causes lattice degeneration?
The exact cause is not fully understood. Lattice degeneration is believed to be related to normal aging changes of the retina and its blood supply. It is more commonly seen in people who are nearsighted (myopic) and may occur in one or both eyes.
Q: Is lattice degeneration serious?
In most cases, lattice degeneration is not serious and does not affect vision. Many people have lattice degeneration for years without any complications. However, because the retina is thinner in these areas, there is a slightly increased risk of retinal tears or detachment, which is why regular monitoring is important.
Q: Does lattice degeneration cause symptoms?
Most people with lattice degeneration have no symptoms at all. Symptoms only occur if a retinal tear or detachment develops. These symptoms may include flashes of light, new floaters, or a shadow or curtain in the vision.
Q: Can lattice degeneration lead to retinal detachment?
Yes, lattice degeneration slightly increases the risk of retinal detachment, but the overall risk remains low for most patients. The majority of people with lattice degeneration never develop a retinal detachment, especially when the condition is carefully monitored.
Q: Does lattice degeneration need treatment?
Lattice degeneration itself usually does not require treatment. Preventive laser treatment may be recommended in select cases, such as when there are associated retinal tears, high-risk features, or a history of retinal detachment in the other eye. Your retina specialist will determine whether treatment is appropriate.
Q: Can lattice degeneration go away on its own?
No, lattice degeneration does not go away, but it often remains stable over time. Many patients live their entire lives with lattice degeneration without any vision problems or need for treatment.
Q: How often should lattice degeneration be monitored?
Monitoring frequency depends on individual risk factors, such as degree of myopia, presence of retinal holes, or symptoms. Most patients are followed with regular dilated eye exams every 6-12 months, and additional imaging may be used when needed.
Q: Can lifestyle or activity increase the risk of complications?
Normal daily activities are generally safe for patients with lattice degeneration. In rare cases, your doctor may advise temporary activity modifications if there are high-risk retinal findings. Protecting overall eye health and attending routine exams are the most important steps.
