If lattice degeneration is area of atrophy of peripheral retinal pigment epithelium, can it be considered analogous to atrophy of skin epithelium?

If lattice degeneration is area of atrophy of peripheral retinal pigment epithelium, can it be considered analogous to atrophy of skin epithelium?

Sort of: Lattice degeneration is retinal thinning of inner retina that may progress to outer layers, when the retinal pigment epithelium can become sec. ...Read more

Atrophy (Definition)

Atrophy usually refers to the skin-as you get older or if you have had alot of sun in the past-the dermis (that is the layer below the top layer which is called the epidermis) gets thinner and the skin looks more wrinked. Muscles and fat can also get thinner -this is another form of atrophy. Even the top layer gets thinner ...Read more

Please explain what the retinal pigment epithelium is?

RPE: The retinal pigment epithelium, or rpe, is a layer of the retina just below the photoreceptors, also known as the rods and cones. The rpe takes care of these photoreceptor cells and is therefore very important in visual function. There are many eye diseases that occur primarily in this layer. ...Read more

Pattern dystrophy of the retinal pigment epithelium: What does this mean?

Pattern dystrophy of the retinal pigment epithelium: What does this mean?

Hereditary dystrophy: Pattern Dystrophy is a hereditary retinal dystrophy that often mimics macular degeneration. However it does not progress in the same manner and can be associated with preservation of good vision depending on the severity of the dystrophy. ...Read more

Can you tell me about pattern dystrophy of the retinal pigment epithelium?

Looks similar to AMD: Pattern dystrophy is a heterogeneous group of dominantly inherited macular disease. It has patterns of deposits of yellow, orange, or pigment changes in the macular area. It may be difficult to differentiate from AMD in late stages. Some may develop Choroidal neovascular membranes. ...Read more

What is the retinal pigment epithelium?

Many functions: The RPE is a layer underneath the retina that serves many roles. Its many functions include light absorption, epithelial transport, spatial ion buffering, visual cycle, phagocytosis, secretion and immune modulation. Without it, the retina degenerates as in various diseases including AMD. ...Read more

What is the retinal pigment epithelium?

Cells under retina: The retinal pigment epithelium are cells under the retina that work to keep your photoreceptors working properly and allow vision. They can become damaged in various diseases, probably the most common being AMD. ...Read more

After eye exam today, I was told I have a very small white spot, called retinal pigment epithelium drop out. However, the dr was not concerned at all. Should I be?

RPE dropout okay: Is a finding that may be quite common and not necessarily associated with anything wrong. As retinal specialists, we pay attention to the pigmentation changes especially in the macula. The rpe "dropout" lesions are usually pretty static and do not progress with time. We like to note where they are though. Pigment density is decreased in some retinal diseases. ...Read more

What is congenital hypertrophy of retinal pigmentation epithelium?

What is congenital hypertrophy of retinal pigmentation epithelium?

It is: A very darkly pigmented lesion of the retina found during an eye exam. It is similar to a mole or nevus, but has some distinctive differences. Unlike a mole, it cannot become cancerous. It does not affect the vision and should be of no concern to you. ...Read more

I have congenital hypertrophy of retinal pigmentation epithelium, any suggestions?

Depends: It depends on how many chrpe spots you have. If you only have one, observation is fine. If you have 4 or more, there is an increased risk for a type of cancer in the colon and you'll want to get that evaluated regularly. ...Read more

Can lattice degeneration be thought of (seen) as warts on the pigment epithelium of peripheral retina?

No: Lattice is a peripheral thinning found commonly in near sighted patients. It can be a risk factor for developing retinal tears which can lead to detachment of the retina. Lattice is not infectious, nor is it caused by a virus as are warts. The pigment epithelium does not get warts. ...Read more

Is an atrophic hole in your retina serious?

Atrophic hole, No: An atrophic hole in the retina is usually not considered to be dangerous. A full thickness atrophic hole can be treated with laser to stabilize it if the surgeon feels that it is a threat and may progress to a detachment. If it progresses to a detachment, that is serious. ...Read more

What is retinal pigmentation and is it serious?

Inherited eye diseas: Retinitis pigmentosa (rp) is a group of similar-appearing eye diseases that are hereditary in nature and can lead to blindness. There is no known effective treatment at this time. Rp often causes night blindness and reduction of peripheral vision. More advanced disease causes loss of central vision. The genetic defect in some autosomal dominant forms of rp is known. ...Read more

What's the meaning of retinal pigmentation?

Trauma, infection: The retina responds to trauma, infection and some inherited conditions by the production of pigment. The ophthalmologist can evaluate this and determine the source of the problem frequently by looking at this pigment. You cannot see your own pigment. ...Read more

With lattice retinal degeneration, how often should you get retinal exams to find new atrophic holes, etc, to prevent RD?

Once per year: Annual exams should be adequate unless you have sudden symptoms of new floaters, flashes of light, veils or curtains in your vision. If any of these develop you should be examined within 48 hours. ...Read more

Do atrophic retinal holes caused by lattice retinal degeneration produce any symptoms if no traction? How to tell if new one / when to go in?

No symptoms. Flash: Atrophic Holes usually cause no symptoms. Flashing lights in the peripheral vision often indicates retinal traction which increases one's risk of retinal tear especially in patients with lattice degeneration and atrophic holes. Increased flashes and floaters are an indication for peripheral retina exam by a qualified ophthalmologist. ...Read more
