What is Lattice Degeneration?
Lattice degeneration gets its name from the crisscrossing, fine, white lines on the surface of the retina, which an eye doctor can see during examination. It occurs in 7–8% of the general population, most often in patients with myopia (nearsightedness) and over the age of 20. It also appears that neither race nor sex is a risk factor. Approximately 45% of those affected have lattice degeneration in both eyes. Patients with lattice degeneration are typically symptom-free.
Lattice degeneration occurs when the outside edge of the retina (away from the central macula), responsible for peripheral vision, shrinks, thins, develops holes, or otherwise atrophies. Clinical features may include retinal thinning, branching, whitish lines on the retinal surface, and even small holes in the retina. In addition, lesions can form.
