What does RPE mean in ophthalmology?
The retinal pigment epithelium (RPE) is an specialized epithelium lying in the interface between the neural retina and the choriocapillaris where it forms the outer blood-retinal barrier (BRB).
What is RPE changes in eye?
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 …
What is RPE thickening?
The retinal pigment epithelium (RPE) is a pigmented layer of the retina which can be thicker than normal at birth (congenital) or may thicken later in life. Areas of retinal pigment epithelial (RPE) hypertrophy usually do not cause symptoms. They are typically found during routine eye examinations.
Is RPE part of the retina?
The pigmented layer of retina or retinal pigment epithelium (RPE) is the pigmented cell layer just outside the neurosensory retina that nourishes retinal visual cells, and is firmly attached to the underlying choroid and overlying retinal visual cells.
What is PVD eye?
Posterior vitreous detachment (PVD) occurs when the gel that fills the eyeball separates from the retina. It’s a natural, normal part of aging. PVD can cause floaters or flashes in your sight, which usually become less noticeable over time. The condition isn’t painful, and it doesn’t cause vision loss on its own.
What is RPE?
The retinal pigment epithelium is a fundamental component of the retina that plays essential roles in visual functions. Damage to the structure and function of the retinal pigment epithelium leads to a variety of retinopathies, and there is currently no curative therapy for these disorders.
Is RPE macular degeneration?
Research suggests that the retinal pigment epithelium (RPE) is where macular degeneration begins. This pigmented layer of cells next to the retina serves as a pass-through between the light-sensitive photoreceptors of the retina and a layer of blood vessels, called the choroid, lying below.
What layers separate in a retinal detachment?
Retinal detachment refers to separation of the inner layers of the retina from the underlying retinal pigment epithelium (RPE, choroid). The choroid is a vascular membrane containing large branched pigment cells sandwiched between the retina and sclera.
What is Chrpe Ophthalmology?
Congenital hypertrophy of the retinal pigment epithelium (CHRPE) is a typically benign, asymptomatic, pigmented fundus lesion. It is a congenital hamartoma of the retinal pigment epithelium (RPE) and occurs in three variant forms: solitary (unifocal), grouped (multifocal) and atypical.
What is a chirpy in the eye?
About CHRPE A flat, pigmented spot within the outer layer of the retina at the back of the eye is called a congenital hypertrophy of the retinal pigment epithelium (CHRPE). The pigmentation of the lesion can range from a light gray to black.
How is the HRT used in ophthalmology?
The results from HRT are used to formulate the most effective individual treatment plan possible. HRT is a simple fast painless test that is performed in your doctor’s office. Your doctor may dilate your eyes before the procedure. You will be seated for the test, and your head will rest in a positioning frame.
How is the retinal pigment epithelium ( RPE ) described?
Description. The retinal pigment epithelium (RPE) is a pigmented layer of the retina which can be thicker than normal at birth (congenital) or may thicken later in life. Areas of retinal pigment epithelial (RPE) hypertrophy usually do not cause symptoms. They are typically found during routine eye examinations.
How does the Heidelberg retinal tomograph ( HRT ) work?
Heidelberg Retinal Tomograph (HRT) Introduction Heidelberg Retinal Tomograph (HRT) is a state-of-the-art imaging method used to evaluate the optic nerve for subtle changes related to glaucoma. The optic nerve carries nerve signals about what you see to your brain for processing. Glaucoma is an eye disorder that results from damage to…
