What does PI mean in Ophthalmology?
PI – Peripheral iridectomy/iridotomy.
What does RPE stand for in eyes?
The retinal pigment epithelium (RPE) performs highly specialized metabolic and transport functions essential for homeostasis of the neural retina (Bok 1993).
What is PL PR in Ophthalmology?
“PL” or “Pl” means “Plano.” The easy way to understand this is to just think of “zero” when you encounter it in a glasses prescription or in any other assessment of refractive error and vision.
What is drusen and RPE?
Drusen are variably sized extracellular deposits that form between the retinal pigmented epithelium (RPE) and Bruch’s membrane. They are commonly found in aged eyes, however, numerous and/or confluent drusen are a significant risk factor for age-related macular degeneration.
What is primary angle closure glaucoma?
Primary angle closure (PAC) is defined as appositional or synechial closure of the anterior chamber angle which can lead to aqueous outflow obstruction and raised IOP, in the absence of glaucomatous optic neuropathy. PAC is generally bilateral.
What is primary angle closure suspect?
Primary angle-closure suspect (PACS) was defined as nonvisibility of the filtering trabecular meshwork for 180° or more in the absence of PAS with normal intraocular pressure (IOP). Primary angle closure (PAC) can be further classified as synechial or appositional.
Where is RPE in the eye?
The RPE is a pigmented layer of cells that are located outside the retina and attached to the choroid. The role of the RPE is to nourish the retinal cells.
What is RPE for 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 does PL mean in visual acuity?
If the sphere indicates “Pl” or “Plano” for both eyes, it means that you do not suffer from myopia or hyperopia. A positive sphere indicates hyperopia. People affected by farsightedness have either an eyeball that is too short, or a retina curvature of that is not pronounced enough.
What does SC and CC mean in Optometry?
CC refers to “with correction” while SC refers to “without correction.” PH refers to “pinhole.” A pinhole is similar to squinting in that it removes the effects of refractive errors.
Does drusen always mean macular degeneration?
Drusen are typically associated with age-related macular degeneration in people over the age of 60; however they can arise as hereditary degenerations in young people. Drusen are a risk factor for macular degeneration but having drusen does NOT mean you have macular degeneration.
What is RPE mottling?
Retinal pigment epithelial mottling + 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. Granular macular appearance. Synonyms.
What is the retinal pigment epithelium (RPE)?
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.
What is the function of RPE in the eye?
The RPE has several functions, namely, light absorption, epithelial transport, spatial ion buffering, visual cycle, phagocytosis, secretion and immune modulation. Light absorption: RPE are responsible for absorbing scattered light.
What is the shape of the surface of the RPE?
The RPE is composed of a single layer of hexagonal cells that are densely packed with pigment granules. When viewed from the outer surface, these cells are smooth and hexagonal in shape.
How is retinal pigment epithelial hypertrophy (RPH) diagnosed?
Retinal pigment epithelial hypertrophy can be diagnosed by ophthalmic examination. This will include a careful history for familial colon disease (polyposes). The eye examination will concentrate on the appearance of the retinal pigment epithelial hypertrophy. These lesions tend to be black or atrophic.
