condition, often inherited, in which there is degeneration of the rods and cones in the retina X Y Z

Any of several hereditary progressive degenerative diseases of the eye marked by night blindness in the early stages, atrophy and pigment changes in the retina, constriction of the visual field, and eventual blindness. Also called pigmentary retinopathy See Free Eye Tests.

(RP). A group of both clinically and genetically heterogeneous hereditary retinal degeneration disorders that are caused by the death of both rod and cone photoreceptors, leading to a complete loss of vision.

A degenerative disorder which affects the retina of the eye. It can be inherited in several ways as an isolated disease and sometimes occurs as one feature of a multiple abnormality disorder.

A rare hereditary disease which is characterized by retinal degeneration and progressive blindness. It begins with night blindness in adolescence or in adult life.

degeneration of the retina manifested by night blindness and gradual loss of peripheral vision, eventually resulting in tunnel vision or total blindness

a genetically inherited condition in which rod cells degenerate causing impaired vision in low light conditions and may eventually lead to diminished peripheral perception.

Progressive disease of the eye which results in the retina becoming hard (sclerosed), pigmented (colored), and atrophying (wasting away). There is no known cure for this condition.

a hereditary, progressive condition RP causes abnormal pigmentation on the retina that can hinder vision. RP affects both eyes and can begin with a loss of night vision, progress to a loss of peripheral vision and “tunnel vision,” and finally result in blindness.

A family of inherited diseases, RP causes deterioration of the retina resulting in night blindness, tunnel vision and loss of sight. More RP resources are available on the Retinitis Pigmentosa page of the Low Vision Gateway web site.

A genetic disorder that causes the degeneration of cells in the retina. If severe, it may lead to complete blindness.

is a group of diseases that affect the very delicate and thin tissue that makes up the retina. (Read about " Retinitis Pigmentosa")

A gradual loss of the field of vision, owing to a degeneration of the light-sensitive nerve cells of the retina.

an inherited condition of the retina in which specific photoreceptor cells, called rods, degenerate

A disease of the eye, resulting from degeneration of a part of the eye called the retina. It affects night vision and peripheral vision, and eventually can lead to blindness.

Hereditary condition in which a person (usually in teen years) notices worsening night vision and then a loss of peripheral vision. Blindness often is the end result. No cure, though vitamins may slow its progression.

This is a hereditary degeneration of the rod and cone layer of the retina. Its early stages are marked by the appearance of tiny pigmented dark spots at the outer edges of the retina associated with a loss of the peripheral, or side vision. In time, the pigment can move centrally and cause the loss of central vision. Night blindness is a typical problem associated with RP.

The progressive loss of peripheral vision, usually beginning with night blindness. Go to Top

Usually inherited condition characterized by progressive degeneration of the retina, resulting in night blindness and decreased peripheral vision.

a eye disease that takes vision away from the periphery and gradually continues to cause ever greater tunnel vision. Low vision aids and CCTVs are useful but large amount of magnification are contra indicated because the patient's field of view is limited.

Retinitis pigmentosa (RP) is the name given to a group of inherited eye diseases that affect the retina. Retinitis pigmentosa causes the degeneration of photoreceptor cells in the retina. Photoreceptor cells capture and process light helping us to see. As these cells degenerate and die, patients experience progressive vision loss. Read More

Condition characterized by the progressive loss of peripheral vision, usually beginning with night blindness.

Any of a number of inherited disorders in which there is a progressive loss of vision. In general, patients with this disorder first experience a loss of night vision, which is then followed by tunnel vision and eventually a loss of central vision.

is a group of inherited diseases that damage the light-sensitive rods and cones located in the retina, the back part of our eyes. Rods, which provide side (peripheral) and night vision, are affected more than the cones that provide color and clear central vision. Signs of RP usually appear during childhood or adolescence. The first sign is often night blindness followed by a slow loss of side vision. Over the years, the disease will cause further loss of side vision. As the disease develops, people with RP may often bump into chairs and other objects as side vision worsens and they only see in one direction – straight ahead. They see as if they are in a tunnel (thus the term tunnel vision).

Progressively blinding disease affecting the pigment in the eye

This hereditary disorder is progressive and is characterized by a hardening of the retina. It causes defective night vision, tunnel vision and, possibly, blindness.

Inherited retinal degeneration associated with night blindness, peripheral vision loss, and eventually, total blindness.

A congenital degeneration of the pigmented layer of the retina leading to a severe loss of peripheral vision. Even though central vision may remain clear, traveling is difficult because of the loss of peripheral vision. In retinitis pigmentosa, the reading area is reduced, although the print may be clear.

The Condition"...There is no treatment for retinitis pigmentosa, although some practitioners believe that vitamin A may slightly delay vision loss..." Recommendation Vitamin A"Some practitioners believe that vitamin A may slightly delay vision loss..."

The Condition"Retinitis pigmentosa (RP) is a group of rare hereditary disorders whose common feature is a gradual deterioration of the light sensitive cells of the retina..." Recommendation Vitamin A"...Professor of Ophthalmology at Harvard Medical School, said that adults who supplemented their diets with 15,000 IU of vitamin A daily had on average about a 20% slower annual decline of remaining retinal function than those not taking this dose..."

A chronic progressive disease that has its onset in early childhood. It is marked by degeneration of the retinal epithelium, esp. the rods, without inflammation; atrophy of the optic nerve; and widespread pigmentary changes in the retina. An early symptom is defective night vision followed by a constricted field of vision.

Retinitis pigmentosa, or RP, is a genetic eye condition. In the progression of symptoms for RP, night blindness generally precedes tunnel vision by years or even decades. Many people with RP do not become legally blind until their 40s or 50s and retain some sight all their life.

Retinitis Pigmentosa : an eye deficiency which leads to a progressive loss of eyesight and eventual blindness.
