PERIPHERAL RETINAL DISEASES
Lattice degeneration is an atrophic disease of the peripheral retina characterized by oval or linear patches of retinal thinning. It is bilateral in one third to one half of affected patients. Condensed vitreous at the margins of the lattice lesions may appear as vitreous opacities and represent regions of increased vitreoretinal adhesion. Retinal tears can occur with posterior vitreous separation pulling on the thinned retina, with an increased risk of retinal detachment. However retinal detachment is a relatively rare complication of lattice degeneration.
Lesions may be isolated or multifocal, variable in dimension, and usually are oriented concentric or slightly oblique to the ora serrata, located within the equatorial region of the fundus, typically inferotemporal.
