Overall, a small percentage of retinal detachments are caused by lattice degeneration with atrophic holes (2.8% from one study). As this cuff typically remains stable over time, it is believed that the overlying liquid vitreous does not communicate with the greater vitreous body. These holes rarely progress to a clinical retinal detachment though may develop a small cuff of subretinal fluid stemming from the overlying liquefied vitreous. This occurs via two mechanisms: (1) atrophic retinal hole or (2) retinal tear.Ītrophic round holes occur within the substance of the lattice lesion and likely represent the end-stage of retinal thinning and subsequent dissolution of tissue. It is well documented that lattice degeneration increases the risk of retinal tears or subsequent retinal detachments.
