You could have lattice degeneration right now and feel completely fine. That's exactly what makes this common retinal condition so easy to overlook — and so important to catch through routine screening. Affecting roughly 6-10% of the general population, lattice degeneration causes no pain, no blur, and no obvious warning signs on its own. Yet in a small percentage of cases, it can quietly set the stage for a retinal tear or detachment. For adults over 40, especially those who are nearsighted or have a family history of retinal disease, understanding this condition is the first step toward protecting long-term vision.
What Is Lattice Degeneration?
Lattice degeneration is a thinning of the peripheral retina that forms a distinctive crisscross, or "lattice-like," pattern of weakened tissue.
Where It Occurs and Why
According to RVAF's detailed overview of lattice degeneration, the condition typically develops at the outer edges of the retina and affects both eyes in roughly one-third to one-half of cases. The exact cause isn't fully understood, but it's believed to involve reduced blood flow to the peripheral retina over time.
Who Is Most at Risk
Lattice degeneration doesn't discriminate by gender or race, but certain factors raise the odds of developing it.
Myopia and Family History
The condition is most common in people with myopia, or nearsightedness, and tends to cluster within families even without a clear inheritance pattern. As RVAF explains, it's often discovered incidentally — meaning most people find out only because they went in for a routine dilated exam, not because anything felt wrong.
Why It Matters: The Retinal Detachment Connection
Think of the retina like a stretched canvas. In areas of lattice degeneration, that canvas becomes thin and fragile, making it more prone to small tears.
The Numbers Behind the Risk
While roughly 30% of retinal detachments occur in eyes with lattice degeneration, the overall risk of detachment for any individual with the condition remains low, estimated at only 1-2%. Still, because a detachment can threaten permanent vision loss within days if untreated, monitoring matters even when the odds are small.
Why Symptoms Alone Can't Be Trusted
Because lattice degeneration itself is silent, waiting for symptoms before scheduling an exam means waiting too long.
Warning Signs of a Related Complication
If a retinal tear or detachment does develop from an area of lattice, symptoms tend to appear suddenly: new floaters, flashes of light, or a shadow or curtain moving across the field of vision. Any of these warrants an urgent evaluation, not a wait-and-see approach.
The Role of the Dilated Eye Exam
A comprehensive, dilated fundus exam is the only reliable way to detect lattice degeneration before it causes a problem.
What the Exam Involves
During the exam, dilating drops widen the pupil so a specialist can examine the far periphery of the retina — the exact region where lattice tends to hide. It's a simple, non-invasive step that can catch a fragile area of retina years before it ever becomes symptomatic.
How Often to Get Screened
Adults over 40, and especially those with myopia, diabetes, or a family history of retinal detachment, benefit from an annual dilated exam rather than waiting for vision problems to prompt a visit.
Treatment Options When Monitoring Isn't Enough
Most cases of lattice degeneration require nothing more than periodic observation. But when a retinal hole or tear is found within an area of lattice, or when the fellow eye has a history of detachment, your doctor may recommend preventive treatment.
Laser Therapy (Barrage Laser)
A Retina Specialist can perform in-office laser treatment that creates a controlled scar around the weakened area, essentially "welding" the retina to the underlying tissue to reduce the risk of a future tear progressing to detachment.
Protecting Your Vision Starts With a Simple Exam
Lattice degeneration is a reminder that healthy-feeling eyes don't always mean healthy retinas. Because this condition and its complications develop silently, a regular dilated eye exam remains the single best tool for catching problems before they threaten your sight. If you're over 40, nearsighted, or simply overdue for a comprehensive retinal exam, don't wait for symptoms to appear. Schedule a consultation with a Retina Specialist at Retina Vitreous Associates of Florida today and give your vision the proactive protection it deserves.
