 The cause is unknown, but pathology reveals inadequate blood flow resulting in ischemia and fibrosis.Lattice degeneration occurs in approximately 6–8% of the general population and in approximately 30% of phakic retinal detachments.Similar lesions are seen in patients with Ehlers-Danlos syndrome, Marfan syndrome, and Stickler syndrome, all of which are associated with an increased risk of retinal detachment.
