Lattice Degeneration

Typically affecting nearsighted patients 25 years and older

Condition


Lattice degeneration is a peripheral retina condition in which the retinal tissue is thinned, atrophied and the blood vessels are fibrosed (scarred) in a “lattice-like” appearance. Lattice lesions, usually localized, appear as round/oval or linear patches in the far peripheral retina. In uncommon cases, it may be accompanied by retinal detachment.

Risk factors


The typical patient with lattice degeneration is over 25 years of age and usually, but not always, nearsighted. There is currently no known procedure for the prevention of lattice degeneration, although accompanying retinal detachment can be prevented with lasers or cryoretinopexy.

Prevalence


Lattice degeneration is present in about 8 percent of the general population, 45% of the time affects both eyes, and occurs in about 30 percent of eyes with retinal detachment.

Symptoms


The patient usually does not experience any symptoms, except for possible complaints of flashing lights.

Treatment


Most of the time, no treatment is needed.  Lasers or cryoretinopexy are sometimes used prophylactically to help prevent retinal detachments in more risky appearing eyes (eyes with atrophic holes, traction, and/or subretinal fluid in the lattice).
