![]() The break may be associated with symptoms or may be asymptomatic. ![]() A break in the retina can be categorized as a tear or a hole. A Cochrane systematic review evaluating surgical interventions for rhegmatogenous retinal detachments is in preparation. This review is concerned with the prophylactic treatment of the asymptomatic retinal breaks and areas of degeneration that might cause rhegmatogenous retinal detachment. Retinal detachments can be rhegmatogenous (caused by a break in the retina) or non-rhegmatogenous (caused by leakage from beneath the retina or by traction (pulling) on the retina). Nevertheless, treatment of these problems is frequently recommended, in spite of the fact that the effectiveness of this therapy is unproven.Ī retinal detachment is a separation of the sensory retina from the retinal pigment epithelium, with an accumulation of fluid in the potential space between them. Retinal tears and holes unassociated with acute symptoms and lattice degeneration are significantly less likely to be the sites of retinal breaks that are responsible for later retinal detachment. This therapy is of value in the management of retinal tears associated with the symptoms of flashes and floaters and persistent vitreous traction upon the retina in the region of the retinal break, because such symptomatic retinal tears are associated with a high rate of progression to retinal detachment. Creation of an adhesion surrounding retinal breaks and lattice degeneration, with laser photocoagulation or cryotherapy, has been recommended as an effective means of preventing retinal detachment. Retinal detachments occur when fluid in the vitreous cavity passes through tears or holes in the retina and separates the retina from the underlying retinal pigment epithelium. Asymptomatic retinal breaks and lattice degeneration are visible lesions that are risk factors for later retinal detachment.
