Does lattice with very small holes have a greater risk of developing into a retinal tear (due to traction) than lattice without holes or unrelated?
Minor difference. Lattice develops as a means for the young retina to stabilize deeper attachments to prevent detachment. This along with the gelatinous nature of the vitreous is very protective. The holes probably reflect slightlly thinner retina and a very slightly increased risk. Detachment is unlikely until past age 40 when the vitreous naturally liquefies and is less protective.
