Since the vitreous hydrogel is attached to the lens and retina, perturbations of the vitreous (e.g., caused by inflammation or surgery) or of the lens can contribute to the development of rhegmatogenous RD by creating retinal traction, which can lead to tear or hole formation. ![]() The vitreous is more firmly attached in three locations: the peripheral posterior lens capsule, the vitreous base that overlies the peripheral edge of the retina (the pars plana and ora ciliaris retinae), and the margin of the optic nerve. The vitreous gel is a homogeneous collagen fibril network with hyaluronic acid molecules filling the interfibrillar spaces. The pathogenesis of rhegmatogenous RD involves the presence of an abnormal retina (i.e., thinned as a result of degeneration, age, or other diseases) that is predisposed to formation of tears or holes, combined with an abnormal vitreous, as with vitreous syneresis (liquefaction), traction (from vitreal floaters or postinflammatory debris), or vitreous detachment. This type of RD is less common than exudative RD in small animals and occurs more frequently in dogs than in cats. Rhegmatogenous RD is associated with the formation of one or more retinal tears or holes. Small areas of active chorioretinitis are associated with focal, low retinal detachments.
