![]() In this case the fluid isĪccumulating between the retina and the pigment layer (RPE). Into the subretinal space and for 2% of patients, leads to "rhegmatogenous" retinal detachment. The overlying liquefied vitreous has the ability to pass through the hole That a full-thickness hole atrophies through the retinaĪt the lattice lesion. The vitreous is then able to move through the retina into the space behind the retina Sometimes retinal thinning is so great that holes develop through the retina at the the vitreous contracts away from the retinaĪnd at the same time becomes more strongly attached to the retina, tearing it, detaching it, or causing.the vitreous gel becomes more liquid over the retina lesion.larger blood vessels stiffen and become clogged.the retina atrophies, forming a lesion, and becomes thinner due to obstructed blood supply.Several things happen as the condition develops: The lattices usually form along the vertical meridians and perpendicular to the retinal equator. Sometimes thinning also occurs in the retinal pigment layer and rarely along the fine blood capillaries. The thinning typically involves the vitreous and the inner layers of the retina. Lattice degeneration may show up as sharply demarcated areas of thinning. The vitreous base lies toward the front of the eye where the retina, vitreous membrane, and pigmented layers firmly attach to each other. The retinal equator is an imaginary boundary midway between the front and the back of the eyeball. Lattice degeneration occurs between the retinal equator and the vitreous base. The other 90% are known as uncomplicated lattice degeneration, with lesions but no tears, holes, or breaks. The fine lines seen in lattice degeneration are present in roughly only 10% of all lesions. They are usually an incidental finding of a dilated ophthalmologic examination that may occur within the lattice (present in 25–35%) and result from progressive retinal thinning. Unlike retinal detachment, these breaks and holes are not associated with pulling between the vitreous and retina. Atrophic means that they are due to the wasting away or diminishing of portions of the retina. Sometimes lesions cause holes or breaks in the retina, which are atrophic in nature. Clinical features may include retinal thinning, branching, whitish lines on the retinal surface, and even small holes in the retina. 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. Patients with lattice degeneration are typically symptom-free. Approximately 45% of those affected have lattice degeneration in both eyes. It also appears that neither race nor sex is a risk factor. It occurs in 7–8% of the general population, most often in patients with myopia (nearsightedness) and over the age of 20. 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.
