Frequently Asked Questions about Retinitis Pigmentosa Q: What is retinitis pigmentosa? Retinitis pigmentosa (RP) is a group of diseases that cause deterioration of the retina, the thin layer of tissue that lines the inside of the back of the eye. The retina captures images that are transmitted to the brain by the optic nerve. Two types of cells within the retina are necessary for vision: rod-shaped cells and cone-shaped cells. Although the reasons are not fully understood, these rod-shaped cells slowly stop functioning in patients with RP. Peripheral (side) vision and night vision depend on these rod-shaped cells of the retina. As the disease progresses over the years, peripheral vision diminishes so that patients often can see only a small tunnel of vision straight ahead. In more severe cases, RP can affect certain cone cells, which are used to see colors and for optimal central vision. Approximately 400,000 Americans have retinitis pigmentosa and other related retinal disorders. Q: What are the symptoms of RP?

Symptoms Diagnosis Expected Duration ... Additional Info What Is It? Retinitis pigmentosa is a disorder in which the rods and cones of the retina (the light receptors of the eye) slowly degenerate. People with retinitis pigmentosa experience progressive loss of night vision, peripheral vision and visual sharpness in both eyes. Over time, the disorder leads to tunnel vision, in which the outer edges of vision are dark leaving a shrinking circle of vision in the center. Eventually, total blindness can result, but most people with retinitis pigmentosa retain some vision even in old age.

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.

Retinitis pigmentosa is a progressive degeneration of the retina that affects night vision and peripheral vision. The cause of this disorder is unknown, but it may be an inherited disorder. The cells controlling night vision, called rods, are primarily affected. Dark pigmentation may be present on the retina. As the disease progresses, peripheral vision is lost as well and may lead to blindness. Signs and symptoms often first appear in childhood, but visual incapacity does not develop until early adulthood. The risk factors are a family history of retinitis pigmentosa. It is a rare condition. For more information, go here

RETINITIS PIGMENTOSA DESCRIPTION: TREATMENT: There is no known treatment for R.P. There is considerable research effort in this direction. Monitoring of retinal degeneration (locus and rate of change) via ERG and ophthalmoscopy of widest retinal periphery. A variety of optical aids may be effective (e.g., magnifiers if fields are not severely restricted, hand telescopes, CCTV, and "pocketscopes" - infra-red devices for highs use). Prism lenses may be useful. Higher levels of illumination may be helpful. IMPLICATIONS: GENETIC COUNSELING IS ESSENTIAL. Functional vision evaluations may need to be "as needed" (rather than annually). Identification of the type of R.P. is essential in establishing prognosis. Retinal specialists are usually better qualified to examine the widest area of the retina viewable. Regular eye exams are desirable, to track the rate and degree of deterioration.

Eye Site Retinitis Pigmentosa Reviewed: Last Updated: 12/01/87 Created: 12/01/87 Revised: More than 100,000 Americans are affected with one of a group of progressive night-blinding disorders collectively known as retinitis pigmentosa (RP). Night blindness refers to difficulty seeing in the dark; it is the initial symptom of RP and usually occurs within the first two decades of life. Within the third decade most patients will also experience some impairment of peripheral, or side vision, which in the majority of instances progresses to a profound loss. In addition, about half of all patients with RP will have variable degrees of cataracts. The diagnosis of RP is suspected due to a history of night blindness; it is confirmed by measurement of a loss in side vision as well as characteristic pigmentary changes on examination of the retina, the light-sensitive structure that covers the inside of the eye. In very young patients and in some adults who do not demonstrate these characteristic pigmentary findings, an electrical recording of retinal function, termed an electroretinogram (ERG), may be necessary to confirm the diagnosis. This test, in addition to annual measurement of visual acuity and side vision, is also used to monitor progression of the disease in RP patients.

La retinitis pigmentosa es el nombre dado a un grupo de desórdenes hereditarios del ojo que envuelven la retina del ojo, la capa nerviosa sensible a la luz que reviste la parte de atrás del ojo, y que causan una reducción o pérdida en la habilidad visual gradual pero progresiva. ¿Cuál es la causa de la retinitis pigmentosa? La retinitis pigmentosa es causada por una variedad de defectos de la retina heredados diferentes que afectan la habilidad de la retina para sentir la luz. Los defectos de la retina pueden encontrarse en las células bastones de la retina (un tipo de células de la retina que se hallan afuera de la porción central de la retina y que ayudan a transmitir la luz sombría y que permiten la visión periférica), las células cono de la retina (un tipo de células de la retina que se hayan dentro del centro de la retina que ayudan a transmitir el color y los detalles de las imágenes), y, o en la conexión entre las células que componen la retina. ¿Cuáles son los síntomas de la retinitis pigmentosa?

Retinitis Pigmentosa Retinitis pigmentosa showing the typical bone spicules pigmentary changes. There are multiple bone-spicules hyperpigmentation in the peripheral retina. In advanced cases, the posterior pole is also involved. The retinal vessels are attenuated and the optic disc is pale. The macula may show cellophane, atrophic or cystoid maculopathy. The condition is bilateral. Other features to look for: drusen in the optic disc cells in the vitreous cataract typically posterior subcapsular cataract keratoconus trabeculectomy (3% of RP develop glaucoma) Look for associated features which may provide clue to diagnosis: hearing aids (Usher's syndrome but beware that patients with syphilis or congenital rubella may also have deafness and pigmentary changes in the retina) Questions: 1. Which conditions may simulate retinitis pigmentosa? Answer Infections: syphilis, congenital rubella, resolving herpes retinitis, treated cytomegalovirus retinitis Drug toxicities such as mellaril, chloroquine and chlopromazine Resolved exudative retinal detachment such as seen in malignant hypertension Blunt trauma 2.

Who is TheRetinaSource.com? Home Retina News Retina Conditions ... 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.
