Retinal detachment, despite being rare is a very serious problem as it can result in blindness and permanent vision loss. Lattice Degeneration can increase your risk of developing a retinal detachment. The cause is not known but is more common in near-sighted people and generally runs in families. Regional developmental absence of the internal limiting membrane versus abnormal vitreoretinal traction dynamics appears to be the most cogent argument proposed. The pathogenesis of lattice degeneration is not well understood, although several theories have been proposed. Lattice degeneration also commonly leads to the development of retinal holes. It is common for the condition to be found in both eyes. It is seen in about 1 out of every 10 people in the general population. Lattice degeneration is the most common type of peripheral retinal degeneration. The far peripheral retina, responsible for the extreme side vision can degenerate and become very week and thin in some cases. Generally, only a small part of the center of the retina is used to view most of the things. The retina is the layer of specialized nerve tissue lining the back of the eye that allows you to see. It is considered to be minimally progressive but retinal detachment may result as its rare complication. By the second decade of life, the prevalence of lattice degeneration is at the peak level. The symptoms typically resolve within 1 to 2 weeks but may not resolve fully.Lattice Degeneration is an atrophic disease of the peripheral retina which is marked by the presence of linear patches of retinal thinning. Some patients also experience some difficulty focusing up close. Possible side effects include an increase in pupil size in the treated eye. Side effects are reasonably uncommon, but the risk of side effects increases with the amount of lattice and treatment required. Lattice degeneration is typically treated with laser to strengthen the retina in areas where it is weak. However, other risk factors such as nearsightedness and a family history of retinal tears or detachment convey additional risks that may prompt your doctor to recommend treatment. The current literature regarding prevention of retinal detachment does not provide sufficient information to strongly support routine treatment of lesions other than symptomatic flat tears. If a new retinal tear or a retinal detachment develops, these should be promptly treated with current techniques. Among patients with lattice degeneration associated with tiny atrophic holes, only 2% will be in danger of a later retinal detachment. Retinal tears are much more common and are ideally discovered and treated before they lead to a retinal detachment. These adhesions represent the chief clinical danger of this disease because of their ability to lead to retinal tears and detachment after PVD.ĭuring the lifetime of a patient with lattice degeneration, the likelihood of having a retinal detachment on this basis is in the range of 1% to 2%. Lattice degeneration is located at the edge of the retina and is associated with abnormally strong adhesions between the retina and the vitreous gel that fills the eye. Depending on symptoms and hole appearance, a decision is made whether to treat the lesion or observe. Occasionally, holes may be found in the lattice. To discover all such lesions, it is necessary to perform a dilated eye exam combined with scleral indentation, where an instrument is used to put gentle pressure on the eyelids to better examine the edge of the retina. Lattice Degeneration represents an area of retinal thinning, usually located near the outer edge of the retina. Lattice degeneration is almost always discovered inadvertently, either in the course of a routine eye examination or in conjunction with symptoms of a PVD. Ultimately, a retinal detachment can occur following a retinal tear. Occasionally, if an acute posterior vitreous detachment (PVD) occurs, a retinal tear may be observed at a lattice lesion the tear then may produce symptoms of this event (floaters or light flashes). No symptoms are associated with this condition. What are the symptoms of Lattice Degeneration? It usually shows an autosomal dominant pattern and occurs in about 8% of healthy individuals of both sexes. Lattice degeneration is a very common, inherited, congenital abnormality of the peripheral retina.
