In rhegmatogenous retinal detachment, lattice degeneration is associated with which type of retinal break?

• A Dialysis at the ora serrata
• B Round atrophic holes within the lattice lesion ✓
• C Horseshoe (flap) tears from dynamic vitreoretinal traction at the posterior edge of lattice
• D Giant retinal tears along the posterior lattice margin

Explanation

Lattice degeneration is characterized by thinning and atrophic change within the lesion, and the breaks most commonly found within lattice are round atrophic holes, which can cause slowly-progressive chronic retinal detachment often with demarcation lines. Horseshoe tears from vitreous traction at the lattice edge also occur but less commonly than atrophic holes within the lattice. Dialyses are associated with blunt trauma and are not a feature of lattice.
