What is retinal pigment epitheliopathy?

What is retinal pigment epitheliopathy?

Epitheliopathy or acute posterior multifocal placoid pigment epitheliopathy (APMPPE) refers to an acquired inflammatory illness affecting the retinal pigment epithelium. It can affect one or both eyes, and is characterized by multiple yellowish white or light-colored lesions that form in the retina.

What is APMPPE eye disease?

Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) is a rare eye disorder of unknown (idiopathic) cause. The disorder is characterized by the impairment of central vision in one eye (unilateral) but, within a few days, the second eye may also become affected (bilateral).

What causes APMPPE?

The exact etiology of APMPPE is unknown, however some believe that it is secondary to a delayed-type hypersensitivity-induced occlusive vasculitis. Gass originally posited that inflammation of the outer retina and RPE causes the APMPPE phenotype.

Is APMPPE an autoimmune disease?

The syndrome of APMPPE has also been associated with other systemic autoimmune diseases such as necrotizing vasculitis,21 Wegener granulomatosis,22 cerebral vasculitis,23 polyarteritis nodosa,24 and ulcerative colitis.

What is Pachychoroid pigment Epitheliopathy?

Pachychoroid Pigment Epitheliopathy PPE is thought to represent a form fruste or precursor of CSCR, as it has features of retinal pigment epithelium disturbances similar to CSCR but without clinical or imaging evidence of acute or chronic subretinal fluid.

What causes retinal pigmentation?

What causes RP? RP is an inherited disorder that results from harmful changes in any one of more than 50 genes. These genes carry the instructions for making proteins that are needed in cells within the retina, called photoreceptors.

What is white dot syndrome?

Abstract. The white dot syndromes are a group of inflammatory chorioretinopathies of unknown etiology which have in common a unique and characteristic appearance of multiple yellow-white lesions affecting multiple layers of the retina, retinal pigment epithelium (RPE), choriocapillaris, and the choroid.

How common is APMPPE?

Acute posterior multifocal placoid pigment epitheliopathy (APMPPE), for example, is an immune-mediated chorioretinal disease that usually affects young adults—about 40% of whom report influenza-like symptoms prior to the onset of visual symptoms. While uncommon, this white-dot syndrome may end up in your chair.

What is Pachychoroid disease?

A “pachychoroid” (pachy-[prefix]: thick) is defined as an abnormal and permanent increase in choroidal thickness often showing dilated choroidal vessels and other structural alterations of the normal choroidal architecture. Central serous chorioretinopathy is just one of several pachychoroid-related macular disorders.

What is Pachydrusen?

While drusen is thought to be diagnostic of AMD, the entity pachydrusen was recently coined by Rick Spaide in 2018 to describe drusenoid lesions, large size of >125 μm and solitary, in the context of a thickened choroid and distinct from the typical soft drusen of AMD [3].

What are the signs of retina problems?

How does epitheliopathy affect the retina in both eyes?

Why do I have contact lens wiper epitheliopathy?

It is believed to result from an increase in friction between the palpebral lid and the opposing bulbar conjunctiva, cornea, or contact lens (Korb et al, 2002; Korb et al, 2005).

What is the severity of lid wiper epitheliopathy?

The severity of LWE is clinically graded for each eye on a discrete 0 to 3 scale (Korb et al, 2005) or a 0 to 4 scale (Willis et al, 2011) on the basis of the horizontal and vertical extent of lid margin staining with sodium fluorescein (NaFl), lissamine green (LG), or rose bengal (RB) vital stains.
