Eventually it cannot fill the whole volume of the eye’s vitreous cavity (which remains the same size during adulthood) and so the gel separates from the retina, located at the very back of the eye cavity. The lesions consist of retinal degeneration leading to an atrophy of the tissues with lipid deposits in the internal retinal layers and they have the same complications and clinical protocols. Over time, the vitreous gel that fills the eye becomes liquid and condenses (shrinks) due to age and normal wear and tear. Many authors consider it to be early stage of lattice degeneration. Snail-track retinal degeneration is a clinical variation of lattice degeneration, occurring mainly in young myopic eyes, characterized by long circumferential areas of retinal thinning with a glistening appearance. It occurs more commonly in but is not limited to myopic eyes. History Patients with lattice degeneration are typically asymptomatic, and the lesions are usually an incidental finding of dilated ophthalmologic examination. The vast majority of patients will have lesions that are completely stable or slowly progressive. If you’ve had a cataract operation, the jelly-like vitreous inside your eye can be disturbed, which may increase your risk of a detached retina. The acute onset of floaters, flashes, peripheral field loss, or central vision loss may indicate the presence of a retinal tear or detachment. PVD can lead to tears in your retina, which may then develop into retinal detachment. Patients with lattice degeneration are asymptomatic. Lesions may be isolated or multifocal, variable in dimension, and usually are oriented concentric or slightly oblique to the ora serrata, located within the equatorial region of the fundus, typically inferotemporal. However retinal detachment is a relatively rare complication of lattice degeneration. Retinal tears can occur with posterior vitreous separation pulling on the thinned retina, with an increased risk of retinal detachment. Condensed vitreous at the margins of the lattice lesions may appear as vitreous opacities and represent regions of increased vitreoretinal adhesion. It is bilateral in one third to one half of affected patients. Lattice degeneration is an atrophic disease of the peripheral retina characterized by oval or linear patches of retinal thinning.
