Lattice degeneration affects the peripheral retina and is found in 6-8% of the population. Understanding this condition is key to maintaining optimal retinal health.
Lattice degeneration is a condition that affects the peripheral retina—the thin layer of tissue in the back of your eye responsible for capturing light and sending signals to your brain. It is a common degenerative change seen in the retina, found in approximately 6-8% of the population. Although the term “degeneration” can sound worrisome, many people with lattice degeneration experience little to no vision problems.
Lattice degeneration involves thinning and structural changes in the retina, particularly in its peripheral regions. During an eye exam, our eye doctors may observe these areas as elongated, circumferential patches with a distinctive appearance, often described as “cigar-shaped” bands. In many cases, these lesions exhibit a whitening or pigmentation pattern that makes them stand out against the normal retinal background.
This condition is generally asymptomatic, meaning that most people do not notice any changes in their vision. It is usually discovered during routine dilated eye examinations. Despite its subtle nature, lattice degeneration is important to understand because it can be linked to a higher risk of retinal tears and detachment, albeit rarely.
Studies indicate that lattice degeneration is present in roughly 6-8% of the general population. For those who have it in one eye, about 50% will also have signs of the condition in the other eye. This bilateral occurrence underscores the importance of regular comprehensive eye exams, especially if you are at risk.
Additionally, it is common for about 40% of lattice lesions to have associated atrophic holes. Although these tiny breaks are usually not problematic on their own, they are a reminder that the thinned retinal tissue is more vulnerable to complications.

During a dilated eye exam, our eye doctors use special lenses and bright lights to closely inspect the retina. Lattice degeneration appears as elongated, circumferential areas that are either lighter in color or display a mix of whitening and pigmentation. These areas are typically oriented in a manner that resembles stretched bands or “cigars” along the edge of the retina.
The affected retina is noticeably thinner than surrounding tissue. One crucial aspect of lattice degeneration is the behavior of the vitreous gel—the clear, gel-like substance that fills the inside of the eye. In areas of lattice degeneration, the vitreous tends to be more tightly adhered to the retina. This increased adherence can create a scenario where the normal aging process, which causes the vitreous to shrink, may lead to a pulling force on the retina near the degenerated areas.
While lattice degeneration itself is not exclusive to any one group, there are several factors that can increase the likelihood of its presence:
Understanding these risk factors is key, as they can help in identifying individuals who might benefit from more frequent monitoring by our eye doctors. It is essential not only for peace of mind but also for proactive retinal health care.
