Sometimes lesions cause holes or breaks in the retina, which are atrophic in nature. Atrophic means that they are due to the wasting away or diminishing of portions of the retina. Unlike retinal detachment, these breaks and holes are not associated with pulling between the vitreous and retina. They are usually an incidental finding of a dilated ophthalmologic examination that may occur within the lattice (present in 25–35%) and result from progressive retinal thinning. The fine lines seen in lattice degeneration are present in roughly only 10% of all lesions. The other 90% are known as uncomplicated lattice degeneration, with lesions but no tears, holes, or breaks.
