Lattice degeneration is described as what process in the retina?

• A. Thinning and stretching of retinal tissue
• B. Increased tear production
• C. Inflammation of the ciliary body
• D. Swelling of the macula

Answer: (A)

Lattice degeneration reflects thinning and stretching of retinal tissue in the peripheral retina. This thinning creates fragile, atrophic areas that are more likely to develop tears under normal vitreous traction. If a tear forms, fluid can enter the retina and cause a rhegmatogenous retinal detachment, which is why lattice degeneration is a recognized risk factor in retinal detachments. The other options describe processes unrelated to this peripheral retinal thinning—tear production is a lacrimal function, inflammation of the ciliary body is uveal inflammation, and swelling of the macula involves the central retina rather than peripheral thinning.
