Retrospective multicentric observational case series data were used. Pigment epithelial detachment followed by retinal cystoid degeneration leads to vision loss in treatment of neovascular age-related macular degeneration. The retinal pigment epithelium (RPE) is a monolayer of highly pigmented hexagonal cells that lies between the neuroretina and the choriocapillaris (CC) [].The RPE has several important functions, including a key function in the visual cycle, the spatial buffering of ions in the sub-RPE space, and the phagocytosis of photoreceptor outer segments []. The phrase "detachment of the retinal pigment epithelium" is used quite often, not always in the correct association and with no clear differentiation between its various types. Fluorescein and . 1,2 What is the retinal pigment epithelium? In the large majority of cases, large serous or typical fibrovascular retinal pigment epithelial detachment (PED) is not observed, although a small sub-RPE component can be noticed . Types of Pigment Epithelial Detachment Based on the type of depositions that may accumulate under the RPE space, we have three types of PED: Drusenoid pigment epithelial detachment - Appear as yellow or yellow-white deposits that result in elevations of the RPE.

In contrast, type 1 MNV is typically associated with the presence of an elevation or a detachment of the RPE and appears as a sub-RPE lesion [ 20 , 21 ]. Retinal pigment epithelium detachment (PED) is an area of retinal pigment epithelium (RPE) elevation with minimal or no sensory retinal detachment resulting from the accumulation of sub-RPE fluid. p igment epithelial detachment (ped) is a pathological process in which the retinal pigment epithelium separates from the underlying bruch's membrane due to the presence of blood, serous exudate, drusen, or a neovascular membrane. Very brief flashes of light (photopsia) in the extreme peripheral (outside of center) part of vision. Retinal pigment epithelium detachment (PED) is a pathological condition in which retinal pigment epithelium is separated from the underlying Bruch's membrane due to the formation of a . The patient appeared to have drusenoid retinal epithelial detachments and minimal intraretinal fluid. The RPE plays a central role in vision because of both physical and metabolic reasons [1,2]. Methods: This is a multicenter genetic association study. We correlated the type of detachment with visual acuity and anatomic outcome. We identified six types of RPE detachments: pseudo-vitelliform, confluent drusen, serous, vascular, and hemorrhagic lesions as well as PEDs associated with a retinal vascular abnormality. This material can include fluid, proteins, fibrous tissue, or blood vessels. Secondly, the lipid nature of this membranous debris creates a hydrophobic barrier in Bruch's membrane, resulting in the accumulation of fluid and enlargement of the detachment.3-6 Different types of PED have been identified in the Treatment with anti-vascular endothelial growth factor agents led to prompt involution of the lesion and resorption of the intraretinal and subretinal pigment epithelium fluid . With indocyanine green angiography (ICGA), drusenoid PED appears as a homogeneous hypolueorescent lesion [4]. Both Type 1 and 3 eyes showed a significant decrease in pigment epithelial detachment size, subretinal fluid, and subretinal hyperreflective material; however, Type 3 eyes had a greater reduction . Purpose: To describe the spectrum of pigment epithelial detachments (PEDs) occurring mainly in age-related macular degeneration and central serous chorioretinopathy and also in other inflammatory, neoplastic and iatrogenic, retinal, and systemic disorders.. Methods: Pigment epithelial detachments are divided into drusenoid, serous, vascularized, or mixed categories. The prognosis for these detachments depends on the underlying disease process. Yu, J. J. et al. The phrase "detachment of the retinal pigment epithelium" is used quite often, not always in the correct association and with no clear differentiation between its various types. Serous Pigment Epithelial Detachment A serous pigment epithelial detachment often causes visual distortion and loss of vision. Retinal Detachment.

Drusenoid pigment epithelial detachment (DPED) is characterized by a fairly well-circumscribed elevation of the retinal pigment epithelium and a confluence of drusen. It is important to identify the specific nature of detachment of the retinal pigment epithelium, and to establish an accurate diagnosis and treatment plan. Classically, three main types of PEDs are noted: a) drusenoid, b) serous, and c) vascularized. The fluid separates the retina from the retinal pigment epithelium, which is the membrane that provides your retina with nourishment and oxygen, causing the retina to detach. Retinal Pigment Epithelial (RPE) Tears, also known as RPE tears or rips, is a phenomenon first described in 1981 [1] in which the RPE acutely tears from itself and retracts in an area of retina usually overlying a pigment epithelial detachment (PED) at the junction of detached RPE and flat RPE, leaving the underlying Bruch's membrane and choroid exposed. The intervening detached cavity may contain a combination of exudate, blood, drusenoid material, and neovascular tissue. The amount of permanent visual loss varies a lot. This presentation will show the clinical characteristics and types of pigment epithelial detachment in non-ARMD cases such as polypoidal choroidal vasculopathy and central serous chorioretinopathy. Pigment epithelium detachment (PED) is an important clinical manifestation of multiple chorioretinal diseases, which can cause loss of central vision. Retinal pigment epithelial detachment is in the family of macular degeneration but is not necessarily associated with wet (new blood vessel growth) macular degeneration. The authors did not report whether the differences in anatomical response resulted in any visual acuity benefit. This kind of detachment happens when you have extra fluid or other material under a layer of cells in the back of your eye, called the retinal pigment epithelium (RPE). Retinal detachment is a sight threatening condition with an incidence of approximately 1 in 10000. Disease. Methods.
