Retinitis pigmentosa Retinitis pigmentosa (RP) is an inherited, degenerative eye disease that causes severe vision impairment due to the progressive degeneration of the rod photoreceptor cells in the retina.etinitis Pigmentosa is the leading cause of inherited blindness, with approximately 1/4,000 individuals experiencing the non-syndromic form of their disease within their lifetime.

- More than 60 percent of cases of blindness among infants are caused by inherited eye diseases such as congenital (present at birth) cataracts, congenital glaucoma, retinal degeneration, optic atrophy and eye malformations.enetics also play a role in vision problems that occur in otherwise healthy eyes. Genetic ophthalmologic researchers now have evidence that the most common vision problems among children and adults are genetically determined.

Mutations and Disease Many mutations have no effect at all. These are called silent mutations. But the mutations we hear about most often are the ones that cause disease. Some well-known inherited genetic disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, phenylketonuria and color-blindness, among many others.All of these disorders are caused by the mutation of a single gene.Most inherited genetic diseases are recessive, which means that a person must inherit two copies of the mutated gene to inherit a disorder.any mutations have no effect at all. These are called silent mutations. But the mutations we hear about most often are the ones that cause disease. Some well-known inherited genetic disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, phenylketonuria and color-blindness, among many others.

- Genetic Changes. Mutations in the OPN1LW, OPN1MW, and OPN1SW genes cause the forms of color vision deficiency described above. The proteins produced from these genes play essential roles in color vision. They are found in the retina, which is the light-sensitive tissue at the back of the eye.

Cure for rare form of color blindness steps closer with novel gene insight Cure for rare form of color blindness steps closer with novel gene insight. In a new study published in PLOS ONE, researchers have uncovered novel insights into two genetic mutations that may be a cause of a rare form of color blindness called achromatopsia, paving the way for a cure for the condition.

What is color blindness? Inherited color blindness is caused by abnormal photopigments. These color-detecting molecules are located in cone-shaped cells within the retina, called cone cells. In humans, several genes are needed for the body to make photopigments, and defects in these genes can lead to color blindness.ome people, however, have a color vision deficiency, which means their perception of colors is different from what most of us see. The most severe forms of these deficiencies are referred to as color blindness. People with color blindness aren’t aware of differences among colors that are obvious to the rest of us.

Causes Non Hereditary Color Blindness. Color blindness has been known to result from a number of causes: Shaken Baby Syndrome: This can cause retina and brain damage and therefore can cause color blindness in infants and children. The damage is permanent so the effects will be carried on into adult life. Trauma: Similar to above, accidents and other traumas can cause swelling in the visual processing center of the brain – the occipital lobe.

Weather The Alps act as a climatic divide running from east to west. Weather forecasts always distinguish between the north side of the Alps, southern Switzerland and the Engadine. The climate of the Alps and of the Jura uplands in the cooler months is mostly raw, rainy, or snowy, with frost occurring above 1,830 m (6,000 ft).t lower levels in the Alpine valleys and on the central Swiss plateau, the temperature is moderate with no extremes of hot and cold, with an average yearly temperature of about 10°C. The temperature decreases about 2° C for every additional 300 m of elevation.
