![]() ![]() ![]() ![]() For more information on the types and causes of retinal detachment see the National Eye Institute’s website at: Retinal detachment can cause permanent visual loss or permanent reduction of visual function, especially if the macula is involved, in which case it is considered a medical emergency in the United States. 3) Exudative, in which fluid accumulates between the neural retina and the retinal pigmented epithelium pushing the two apart the retinal tissue is not torn. 2) Tractional, in which some force (usually contracting cells or vitreal “strands”) acts on the surface of the retina to pull it away from the retinal pigmented epithelium. In this form the retina experiences a physical tear through the retinal layers and the torn retina peals away from the retinal pigmented epithelium by the movement of fluid into the space between the two. There are three recognized types of retinal detachment in clinical practice: 1) Rhegmatogenous, the most common type. It also creates a greater distance between the photoreceptors and their sole blood supply, the choroidal circulation.Ĭlinical retinal detachments occur as different types ![]() When the retina is separated from its normal position apposed to the RPE surface, it is said to be “detached.” This detachment creates a pathological, fluid-filled space between the neural retina and the retinal pigmented epithelium. The retina is firmly attached to the apical surface of the retinal pigmented epithelium, or RPE (see earlier retinal anatomy sections). Lewis, Kenneth A Linberg, Edward Barawid and Mark V. ![]()
