Three other forms of autosomal dominant corneal dystrophy are also caused by mutations in this gene, which maps to chromosome 5q31. Lattice dystrophy is caused by mutation in the gene encoding keratoepithelin. Early lattice and recurrent lattice arising in the donor cornea responds well to treatment with the excimer laser. Although people with lattice dystrophy have an excellent chance for a successful transplant, the disease may also arise in the donor cornea in as little as three years. In this case, a corneal transplant may be needed. By about age 40, some patients have scarring under the corneal epithelium, resulting in a haze on the cornea that can greatly obscure vision. With effective care, these erosions usually heal on the surface within three days, although occasional sensations of pain may occur for the next 6-to-8 weeks.Īlthough lattice dystrophy can occur at any time in life, the condition usually arises in children between the ages of 2 and 7. In some cases, an eye patch may be used to immobilize the eyelids. ![]() ![]() To ease this pain, eye drops and ointments may help by reducing the friction on the eroded cornea. Even the involuntary act of blinking can be painful. These erosions also expose the nerves that line the cornea, causing severe pain. These erosions alter the cornea's normal curvature, resulting in temporary vision problems. This condition is known as recurrent epithelial erosion. These abnormal protein fibers can accumulate under the cornea's outer layer - the epithelium - causing it to erode. They also gradually converge, giving the cornea a cloudiness that may also reduce vision. Over time, the lattice lines grow opaque and involve more of the stroma. These deposits in the stroma appear on an eye examination as clear, comma-shaped overlapping dots and branching filaments, creating a lattice effect. What does lattice mean Proper usage and audio pronunciation (plus IPA. But the authors in 1 defined an L-fuzzy lattice based on a fuzzy set of a crisp lattice, so the scope is very limited, and they gave its characterizations. lattice noun A partially ordered set in which every pair of elements has a unique supremum and an infimum. lattice noun a regular spacing or arrangement of geometric points, often decorated with a motif. Lattice dystrophy: A form of hereditary corneal dystrophy in which there is an accumulation of amyloid deposits, or abnormal protein fibers, throughout the middle and anterior stroma of the cornea. Definition of lattice in the Dictionary. lattice noun A flat panel constructed with widely-spaced crossed thin strips of wood or other material, commonly used as a garden trellis.
