Signs/Symptoms Treatment Retinitis Pigmentosa Overview Retinitis pigmentosa (RP) is a rare, hereditary disease that causes the rod photoreceptors in the retina to gradually degenerate. The rods are located in the periphery of the retina and are responsible for peripheral and night vision. Cones, another type of photoreceptor, are densely concentrated in the macula . The cones are responsible for central visual acuity and color vision. The disease may be X-linked (passed from a mother to her son), autosomal recessive (genes required from both parents) or autosomal dominant (gene required from one parent) trait. Since it is often a sex-linked disease, retinitis pigmentosa affects males more than females. People with RP usually first notice difficulty seeing in dim lighting and gradually lose peripheral vision. The course of RP varies. For some, the affect on vision may be mild. Others experience a progression of the disease that leads to blindness. In many cases, RP is diagnosed during childhood when the symptoms begin to become apparent. However, depending on the progression of the disease, it may not be detected until later in life.

The Information Service of the Canadian Ophthalmological Society Retinitis pigmentosa 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 horizon-particularly in the area of genetic research-as yet, there is no cure for retinitis pigmentosa. The retina is attached to the optic nerve and transplants are not yet an option.

Text Version Retinitis pigmentosa What is retinitis pigmentosa (retinal dystrophy)? Retinitis pigmentosa (RP) is a congenital inherited condition which causes the breakdown of pigment in the retina. As the retina gradually breaks down images are not transmitted to the brain. What causes RP? Pigmented cells, which respond to light and send signals to the visual cortex. The reason for this is not known. How does RP affect vision? Retinitis pigmentosa usually starts, with difficulty seeing at night (night blindness). During the day people may be able to see very well. However, as the condition worsens people may experience difficulty seeing in dim light. Eventually RP may progress to loss of peripheral vision, which leads to tunnel vision Colour vision may also be affected. Read this interview with a person who has RP.

Retinitis Pigmentosa Definition Symptoms Treatment Clinic Information Definition Retinitis Pigmentosa (RP) refers to a group of diseases which cause a slow but progressive vision loss. In each of them there is a gradual loss of the light-sensitive retinal cells called rods and cones. An estimated 200,000 people in the United States have some form of RP. Most forms of RP are inherited or genetic, though its signs do not necessarily appear in every generation. Learning more about your family history may help you and your doctor to make informed decisions about treatment and eventually a cure for RP. In some cases, RP may be associated with other health problems, such as hearing loss. People with RP may also develop other treatable eye diseases, such as glaucoma and cataract Symptoms Night blindness Loss of peripheral vision (Symptoms usually start during young adulthood, although RP may be seen at any age.) The symptoms described above may not necessarily mean that you have retinitis pigmentosa However, if you experience one or more of these symptoms, contact your eye doctor for a complete exam.

Appointment Retinitis Pigmentosa What is retinitis pigmentosa? Retinitis pigmentosa is actually the name given to a group of hereditary eye disorders, all of which involve the eye's retina, the light-sensitive nerve layer that lines the back of the eye, and all of which cause a gradual, yet progressive, loss or reduction in visual ability. What causes retinitis pigmentosa? Retinitis pigmentosa is caused by a variety of different inherited retinal defects all of which affect the ability of the retina to sense light. The retinal defect may be found in the retina's rod cells (a type of retinal cell found outside of the central portion of the retina that help to transmit dim light and allow for peripheral vision), the retina's cone cells (a type of retinal cell found inside the center of the retina that help to transmit the color and detail of images), and/or in the connection between the cells that compose the retina.

In these conditions the retina slowly degenerates losing its ability to transmit images to the brain. In advanced stages of the conditions characteristic clumps of pigment appear in the retina. Often the first symptom is night blindness, followed by narrowing of side vision leading to 'tunnel' vision. Inheritance patterns For retinitis pigmentosa inheritance may be autosomal dominant (usually milder forms of the condition), autosomal recessive or X-linked. In other related conditions inheritance patterns depend upon the specific condition. For example Best disease, butterfly-shaped dystrophy, and Bull's-eye dystrophy are autosomal dominant.

Causes, incidence, and risk factors Return to top Retinitis pigmentosa commonly runs in families. The disorder can be caused by defects in a number of different genes which have recently been identified. The cells controlling night vision, called rods, are most likely to be affected. However, in some cases, retinal cone cells are most damaged. The hallmark of the disease is the presence of dark pigmented spots in the retina As the disease progresses, peripheral vision is greadually lost. The condition may eventually lead to blindness , but this is usually not complete blindness. Signs and symptoms often first appear in childhood, but severe visual problems do not usually develop until early adulthood. The main risk factor is a family history of retinitis pigmentosa. It is an uncommon condition affecting about one in 4,000 people in the U.S.

Retinitis Pigmentosa Retinitis pigmentosa is an inherited condition of the retina in which specific photoreceptor cells, called rods, degenerate. The loss of function of these rod cells diminishes a patient's ability to see in dim light and with time can also diminish their peripheral vision. Retinitis pigmentosa is probably caused by mutations in at least ten different genes. Until seven years ago, none of the retinitis pigmentosa genes were known. In 1989, however, researchers in Ireland found that the mutation that caused retinitis pigmentosa in a large Irish family was very near if not within the rhodopsin gene. Soon thereafter, researchers at Harvard identified a specific mutation in the rhodopsin gene that caused retinitis pigmentosa. Our laboratory developed an assay for rhodopsin mutations based on a technique developed by Dr. Sheffield known as "GC-clamped denaturing gradient gel electrophoresis." Using this assay, we have identified over 50 different rhodopsin mutations in our patients. Retinal appearance of a patient with retinitis pigmentosa caused by a mutation in the rhodopsin gene. The brown pigment in the lower half of the eye is the finding that gives the condition its name. The sharp demarcation between the normal retina above and the abnormal retina below is characteristic of rhodopsin mutations.

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.
