![]() ![]() Overall, following an acute retinal tear, the risk of retinal detachment is about 52%, and this is the group that requires treatment. The presence of subretinal fluid is taken as a bad sign in such cases. This may lead to clinical or subclinical retinal detachment. In a rating decision in April 1993, service connection for bilateral lattice degeneration, vision 20/20 bilaterally was granted with a noncompensable disability rating assigned. However, the same pull on the retina that produced the tear may also cause the retina to continue to detach. ![]() ![]() The retinal break in such cases may be hard to find because it is covered by the flap. Operculated tears are produced by traction and progress to retinal detachment in up to 20% of cases.įlap tears that produce symptoms have up to 40% risk of producing retinal detachment, as opposed to 0-10% for those tears that are asymptomatic. Only 2 in 100 atrophic holes, however, progress to retinal detachment. This accounts for less than a third of rhegmatogenous retinal detachments. Retinal holes may occur in lattice degeneration of the retina. The most common cause of a retinal hole is posterior vitreous detachment. This is called rhegmatogenous retinal detachment. It allows fluid to seep underneath the sensory or photoreceptor layer of the retina, peeling it off from the retinal pigment epithelium underneath. Retinal tears and retinal detachmentĪ retinal tear or break is any tear leading to a discontinuity in the full thickness of the retina. Finally, it peels off the macula and this leads to posterior vitreous detachment.Īs the vitreous shrinks, the places where it is firmly attached undergo traction, and this may lead to retinal tears. Finally the vitreous collapses on itself, leading to its pulling away from the retina, starting from the back of the eyeball. The fibrils become coarser, and liquefaction takes place. With advancing age, the vitreous loses its gel-like consistency. Along the edges of an area of lattice degeneration.The macula, which is the central part of the retina where the cones are concentrated.The base of the vitreous where it is attached to the ora serrata of the retina.The vitreous is a mass of jelly traversed by millions of collagen fibrils, which attach to the retina at certain spots. ![]()
