The cells controlling night vision, called rods, are most likely to be affected. However, in some cases, retinal cone cells are most damaged.

They are the first to link two new gene mutations in two French-Canadian families to loss of vision in humans. Their findings are published in this month's issue of the American Journal of Ophthalmology. This project was funded by the Canadian Institutes of Health Research (CIHR), les Fonds de la recherche en santé du Québec (FRSQ) and the Canadian Foundation Fighting Blindness.

Retinitis Pigmentosa "During the day it's like walking in a tunnel, but at night I am wholly blind" The Problem The group of conditions known as Retinitis Pigmentosa (RP) is the most common cause of inherited blindness. There is an initial loss of rod photoreceptors, which die off in the outer part, or periphery, of the retina. Over time, cell death advances inexorably towards the centre of vision, the macula, and the cones are also lost. The devastating progression of the disease is clearly reflected in the symptoms. Loss of night vision is a typical early sign. Peripheral daylight vision then progressively deteriorates culminating in tunnel vision and in some cases complete blindness. Some forms of RP are present at birth whilst others appear in later life. The progression of RP is unstoppable. Most people with the disease are registered blind before they reach their fortieth birthday. How does it happen? RP results from a mutation in one or more genes and approximately one in every 80 people is a carrier of one of these mutations. Often, however, RP develops only when both copies of the gene are mutated. So, a child may be born with RP to parents who do not have the condition but carry the gene. Similarly, someone with RP may have both affected and unaffected children. Spectacular progress has been made in identifying many mutations in a large number of genes that cause retinitis pigmentosa and related conditions at the Institute of Ophthalmology and patients from Moorfields have contributed hugely to this success. At the same time as trying to find more mutations in more genes we are now using the knowledge gained so far to understand how a given mutation can lead to cell death. We believe that in this way new treatments will become available to patients. Some of our innovations in this exciting and challenging area are outlined later in this section.

MAIN SEARCH INDEX Retinitis pigmentosa Definition Description Causes and symptoms Diagnosis ... Resources Definition Retinitis pigmentosa (RP) refers to a group of inherited disorders that slowly leads to blindness due to abnormalities of the photoreceptors (primarily the rods) in the retina. Description The retina lines the interior surface of the back of the eye. The retina is made up of several layers. One layer contains two types of photoreceptor cells referred to as the rods and cones. The cones are responsible for sharp, central vision and color vision and are primarily located in a small area of the retina called the fovea. The area surrounding the fovea contains the rods, which are necessary for peripheral vision and night vision (scotopic vision). The number of rods increases in the periphery. The rod and cone photoreceptors convert light into electrical impulses and send the message to the brain via the optic nerve. Another layer of the retina, called the retinal pigmented epithelium (RPE), may also be affected. In RP, the photoreceptors (primarily the rods) begin to deteriorate and lose their ability to function. Because the rods are primarily affected, it becomes harder to see in dim light, thus causing a loss of night vision. As the condition worsens, peripheral vision disappears, which results in tunnel vision. The ability to see color is eventually lost. In the late stages of the disease, there is only a small area of central vision remaining. Ultimately, this too is lost.

Home What's New Search Site Français Retinitis Pigmentosa What is Retinitis Pigmentosa? Causes and Symptoms Treatment Research What is Retinitis Pigmentosa? Retinitis pigmentosa (RP) refers to a group of diseases which tend to run in families and cause slow, but progressive loss of vision. The retina is the tissue which lines the inside of the eye and sends visual images to the brain. In RP, there is gradual destruction of some of the light sensing cells in the retina. Causes and Symptoms The cause of retinitis pigmentosa has not been clearly identified. About fifty percent of RP cases are sporadic with the remaining cases being hereditary. Learning more about the history of people with RP may help predict how the disease will progress for the affected person, although variations can exist even from person to person within a family. The first symptoms usually start during young adulthood, although it may be seen first at any age. The two most common symptoms are night blindness (where adjusting to the dark happens very slowly) and the loss of side vision. Loss of side or peripheral vision makes mobility very difficult. Once this occurs, a person is left with only central vision (as if looking down a tunnel). Treatment While developments are on the horizonparticularly in the area of genetic researchas yet, there is no cure for retinitis pigmentosa. The retina is attached to the optic nerve and transplants are not yet an option.

German/Deutsch Italian/Italiano Portuguese/Portuguese Our research aims at (1) discerning the disease mechanisms that underlie degenerative disorders of the retina, particularly those types collectively known as retinitis pigmentosa (RP), and (2) using this knowledge to design mechanism-based therapies that are effective and easily available to large groups of patients. The Art of War , the classic book on strategy, articulated the principles of adaptation and impasse. Can this ancient philosophy aid in our search for the answer to the RP riddle? Based on Master Sun's teaching, our research focuses on the cellular and molecular signaling mechanisms that operate in the diseased retina, especially those steps common to a variety of hereditary retinal disorders, each having a different molecular etiology. Studying such common pathways would help to elucidate general biological principles that govern the collective response of the retinal cells to injury. Accordingly, any successful therapeutic intervention that aims at these common mechanisms could be applicable in the treatment of broad classes of retinal degeneration.

Although Retinitis Pigmentosa (RP) would not itself eliminate the possibility of refractive surgery , there are some concerns that indicate current refractive surgery techniques and technology may not be suitable for a person with RP. As there are many types of RP, the symptoms can vary but in the most common type an early symptom is difficulty seeing at night or in areas of poor illumination. The disease is progressive and the field of vision gradually decreases resulting in the condition often referred to as Tunnel Vision . In another type of RP, the side vision is retained for some time but there is central loss leading to an inability to read or carry out close work.

Site Search: Shop Online View Shopping Cart Customize Site To Your Vision Home ... Contact Us Retinitis Pigmentosa Retinitis Pigmentosa (RP) is one of a group of inherited visual disorders that causes the degeneration of the retina of the eyes. Vision gradually decreases and may eventually be lost. RP can be associated with deafness and other malfunctions, central nervous system and metabolic disorders, and chromosomal abnormalities. Most cases of Retinitis Pigmentosa take a long time to develop and vision loss is gradual. Signs usually appear during childhood or adolescence, beginning with night blindness followed by a slow loss of peripheral vision. The disease will cause further loss of side vision and eventually, people with RP may often bump into chairs and other objects as their vision becomes limited to one direction. They can only see straight ahead, as if in a tunnel, which gives the disease its common term tunnel vision. Not much is known about the cause of Retinitis Pigmentosa, except that it is inherited. Sometimes the disease is genetically dominant, meaning only one gene needs to come from a parent for the child to have Retinitis Pigmentosa. Other times the disease is X-linked, meaning that only one gene passed from the mother will cause the child to develop the disease. While there is no cure for RP, research indicates that vitamin A and lutein may slow the rate at which the disease progresses. Occupational therapy is a good idea before too much vision is lost since it may be easier to learn how to work around vision loss while vision is still available.
