What causes a pigment epithelial detachment?

Pigment epithelial detachment is a condition that happens when specific layers of cells behind your eye come apart, or get detached. 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).

What are retinal pigment epithelial changes?

As the retinal pigment epithelium (RPE) ages, a number of structural changes occur, including loss of melanin granules, increase in the density of residual bodies, accumulation of lipofuscin, accumulation of basal deposits on or within Bruch’s membrane, formation of drusen (between the basal lamina of the RPE and the …

How is pigment epithelial detachment treated?

Treatment. Currently no treatment for serous PED is proven effective, nor are recommendations for treatment guidelines established. Several strategies, however, have being used to treat vascularized PEDs, including laser photocoagulation, photodynamic therapy (PDT), intravitreal steroids and anti-VEGF therapy.

Does retinal pigment epithelium regenerate?

Clinical observations have shown that in vivo the RPE has very limited ability to regenerate and consequently degeneration of these cells leads to photoreceptor death and irreversible blindness.

Can retinal cells regenerate?

Eye injuries and certain eye diseases that damage retinal tissue can lead to blindness. In the mammalian eye, injured retinal cells can’t regenerate. Retinal cells do naturally regenerate in zebrafish.

What does pigment epithelial Detachment (PED) involve?

What does pigment epithelial detachment (PED) involve? Pigment epithelial detachment (PED) is a manifestation of neovascular (wet) age-related macular degeneration (AMD). There are different forms of PED, and some have a better prognosis than others, but unfortunately, all forms of PED can cause progressive visual loss.

What is retinal pigment epithelium mottling?

Definition: Mottling (spots or blotches with different shades) of the retinal pigment epithelium, i.e., localized or generalized fundal pigment granularity associated with processes at the level of the retinal pigment epithelium.

What does pigment epithelium of Eye Mean?

Pigment Epithelium of Eye. The layer of pigment-containing epithelial cells in the RETINA; the CILIARY BODY; and the IRIS in the eye.
