Lattice Degeneration
Clinical Findings:
The vast majority of affected patients are asymptomatic with lattice being noted as an incidental finding on a dilated retinal examination. Some patients may complain of photopsias and floaters. Typical lattice consists of sharply demarcated spindle-shaped areas of retinal thinning usually located in the retinal periphery between the equator of the retina and the posterior border of the vitreous base (Fig. 26.1.1). Lattice degeneration occurs more frequently temporally and superiorly in the retina. The retina may be thinned and atrophic. Atrophic holes are the most commonly seen type of retinal break, which typically remain stable, and are rarely associated with retinal detachments. Occasionally, vitreous traction over lattice can cause formation of horseshoe retinal tears which may result in retinal detachment.
