Understanding the Visual Problems of Retinitis Pigmentosa Richard L. Windsor, O.D., F.A.A.O. Laura K. Windsor, O.D. Retinitis pigmentosa is a term coined by Donders in 1855. It is not one disease, rather a group of retinal diseases with common attributes. The incident seems to be about one in every 4,000. It can be inherited by at least three different methods. Severity and speed of vision loss vary with each form of inheritance. The following are problems common to RP. Tunnel Visual Field Progressive loss of visual fields is a hallmark of RP. The visual field loss often begins as a donut like ring in mid-periphery. As it progresses both centrally and peripherally, the resultant tunnel vision begins to affect the patient’s activities, driving and mobility. Many patients still drive automobiles in the early stages of RP, but the risks for accidents increase as the field reduces. The functional field will be worse at night and in bad weather. Even RP patients in the early stages should not drive in these situations. As the field loss progresses, daytime driving must be curtailed. Studies suggest that on average, the visual field of the RP patient declines by 5% of the remaining field per year.

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.

NEWS FLASH !!! NEW GENE FOR RP DISCOVERED IN CAPE TOWN The geneticists at the Department of Human Genetics at the University of Cape Town have made another dramatic discovery- a new gene mutation causing a dominant form of Retinitis Pigmentosa. This dedicated team led by Professors Raj Ramesar and Jacqui Greenberg have identified the exact location of the gene causing RP in a large South African family. This gene find, the second discovery of an RP gene by this team, was thanks to the participation of dozens of South Africans affected by Retinitis Pigmentosa [RP]. This particular type of RP is caused by a single gene mutation that can be inherited from either parent. RP starts off with night blindness, followed by loss of side vision which leads to tunnel vision and sadly partial blindness. This particular gene is expressed in the tiny blood vessels underneath the retina, the lens of the eye and even in the kidneys. The South African team collaborated with Dr William Sly from Missouri, USA, to find the gene.

Your donation to RP International will help to fight blindness. R.P. = BLINDNESS It's as simple as that! This equation is the unfortunate reality for millions of children and adults with degenerative diseases of the retina. With your help, we at RP INTERNATIONAL can continue our fight against blindness and change the equation to read: We have found a cure for R.P. WHO NEEDS YOUR GIFT? CHILDREN: Like other diseases, RP strikes people of all ages. Unfortunately children are most commonly diagnosed. Day by day, children slowly lose a little more of their vision. ADULTS: While some people with RP will be totally blind by the age of 20, others are able to maintain partial sight into later years. These people make up a group called: "The Sighted Blind" WHERE YOUR MONEY GOES! RESEARCH: Our research advisory board invites requests for funds from prestigious research centers, then evaluates them and awards the most promising. We are determined to stop RP within this generation. INFORMATION SERVICES: It is more difficult to raise funds for diseases which are little known to the public. Despite the millions who have retinal degenerative diseases, names like Retinitis Pigmentosa (RP) Macular Degeneration and Usher's Syndrome are unfamiliar to most ears. We're spreading the word. HUMAN SERVICES: Counseling and comforting victims and their families occupies a tremendous amount of our time and effort. We help the blind and partially sighted.

Western Australian Retinitis Pigmentosa Foundation Fighting Blindness What is Retinitis Pigmentosa? Retinitis Pigmentosa is the name given to a group of diseases which affect the retina of the eye. The retina, located in the back of the eye, is the part of the eye that acts like the film in a camera. It is a delicate layer of cells which picks up the picture and transmits it to the brain - where "seeing" actually occurs. In RP, the retina begins to degenerate, which causes vision to diminish. One of the earliest symptoms of RP is difficulty seeing at night or in dimly lit places (night blindness). Later there is a reduction in side (peripheral) vision. The symptoms of RP generally increase over the years. It is known that certain cells in the retina, known as rods and cones, die in RP. The cause of cell death however, is not known at present, but research provides us with the opportunity to seek solutions. RP bodies throughout the world support research in a number of medical centres and hospitals internationally to find the cause, prevention and treatment of retinal degenerative diseases like Retinitis Pigmentosa, Usher syndrome and Macular Degeneration. Some of these centres also provide a clinical evaluation of the patient's RP or other retinal degenerations. They may also perform special tests requested by the patient's own ophthalmologist. Through the efforts of RP organisations in many countries, the number of highly qualified investigative scientists working full time on RP and related diseases continues to grow. Research efforts into these types of retinal diseases are difficult because there is no opportunity to safely biopsy - that is, remove and examine living retinal tissue under a microscope - the delicate eye.

Western Australian Retinitis Pigmentosa Foundation Back to RP Home CLINICAL DESCRIPTION DIAGNOSIS PROGNISIS ... WHAT ARE THE OBJECTS OF RP GROUPS? In this condition, the cone cells situated at the macula, deteriorate in function and eventually die. The rod cells generally remain in tact. Symptoms usually start at a young, age - usually under 20 when decreased central vision is first noticed. TOP CLINICAL DESCRIPTION On examination, the retina of affected individual shows a macular lesion (structural change) surrounded by yellow-white flecks, or spots, with irregular shapes. The retina consists of layers of light-sensing cells that line the inner back wall of eye and are essential in normal vision. The macula is located in the centre of the retina and is responsible for the fine, detailed central vision used in reading and colour vision. TOP DIAGNOSIS The diagnosis is usually made as a result of deterioration in visual acuity and typical appearances around the macula when the ophthalmologist looks into the eye. Electrical tests, such as the electroretinogram (ERG),electrooculogram and dark adaption testing, can measure the progress of the disease, but are not usually necessary for its diagnosis. TOP PROGNOSIS People with Stargardt's disease start to experience difficulty with reading and fine handbook as well as distinguishing colours. These symptoms progress with age. In some, this deterioration is rapid, while in others it is much slower. There is no way of detecting how fast this deterioration will occur in any individual. By the age of 50, about half will have a visual acuity of 6/60 or worse (see below for definition of "legal blindness"). People with Stargardt's disease do not usually have a problem with peripheral vision, and hence usually have little problem with bumping into objects when moving around. They may however experience difficulties in adjusting to light.

RETINITIS PIGMENTOSA SIGNS AND SYMPTOMS Patients with retinitis pigmentosa (RP) may present with varying symptoms. The onset is often gradual and insidious, and many patients fail to recognize the manifestations of this condition until it has progressed significantly. When patients do report symptoms, they commonly include difficulty with night vision (nyctalopia) as well as loss of peripheral vision. Many patients with RP also experience photopsiae as the disorder progresses; typically they report small flashes of light or a twinkling, shimmering sensation in the midperipheral or peripheral field. These are believed to represent aberrant electrical impulses from the degenerating retina. Central visual acuity is generally not affected until the very late stages of RP, although variants have been encountered that cause devastating macular compromise early in the disease course (e.g., X-linked recessive RP). Color vision is typically remains intact as long as visual acuity is better than 20/40. Attenuation of the retinal arterioles is the earliest observable sign in RP. Retinal pigmentary changes occur in the form of fine mottling or granularity with surrounding areas of atrophy. Later, stellate pigment hyperplasia may be noted at perivascular locations in the midperipheral retina. These hyperplastic formations are often referred to as "bone spicules."

35. RETINITIS PIGMENTOSA retinitis pigmentosa retinitis pigmentosa or RP is a group of geneticallydetermined, progressive degenerations of the rods and cones of the retina. http://www.medhelp.org/lib/retinit.htm

RETINITIS PIGMENTOSA James D. Reynolds, M.D., Univ. of Arkansas School of Medicine Retinitis pigmentosa or RP is a group of geneticallydetermined, progressive degenerations of the rods and cones of the retina. The term retinitis pigmentosa was coined in 1857 by Donders, and like many older terms, it is a misnomer. Despite the "itis," there is no inflammatory or infectious component to this group of diseases. RP classically occurs as an isolated, hereditary condition, but it can be associated with a variety of other diseases. Physiology The retina is the actual sense organ of the eye. The rest of the eye provides support, nourishment, and focusing power. The retina contains several layers of cells, but the group of cells that initially responds to light are the rods and cones. These extremely specialized and sensitive cells transform light energy into electrical energy which is processed in the retina and transmitted to the brain via he optic nerve. Compared to the cones, the rods are a more sensitive, less discriminating cell population. They function best in the dark or near dark. The cones are less sensitive, but more discriminating. They function in well-lighted conditions and are the cells which provide us with our optimal 20/20 vision. The cones are also the cells responsible for the perception of color. These two groups of cells form a complimentary dual system. Classification Generalized rod-cone degenerations are classified in a variable way and few authors agree completely on the classifications. The following grouping is somewhat simplified:
