![]() Isolated tears are considered the most severe retinal degeneration with high risk of rhegmatogenous retinal detachment. Peripheral retinal tear is a deep defect in the sensory retina. However, the indications for prophylactic laser treatment are not universally accepted. Retinal tuft is a small area of retinal degeneration, in which retina is attached to and pulled by the vitreous causing a considerable vitreous traction, that often leads to retinal tears and detachments. Laser surgery does not always prevent the retinal detachment because new retinal tears can occur in seemingly healthy retina therefore prophylactic laser treatment remains controversial. Vitreous traction often causes retinal tears and rhegmatogenous retinal detachment making this condition a severe peripheral vitreochoreoretinal degeneration. Lattice degeneration appears as retinal thinning with the loss of neurosensory layer and marked vitreoretinal adhesion at the margins. This degeneration is often complicated by retinal holes, less frequently by flap tears with traction, and secondary retinal detachment. Snail-track degeneration is characterized by retinal thinning, vitreous liquefaction above the lesion, and vitreoretinal tractions, that often cause retinal tears. In this chapter, we demonstrate different variants of OCT scans of the main vitreoretinal peripheral degenerations: snail-track degeneration, lattice degeneration, retinal tufts and peripheral retinal tears.
