What genetic diseases cause blindness?
In adults, glaucoma and age-related macular degeneration are two of the leading causes of blindness, and both appear to be inherited in a large portion of cases. Researchers have mapped several genes for glaucoma and are starting to identify genes involved in macular degeneration.
What are the genetic eye diseases?
There are more than 350 hereditary eye diseases, such as albinism, aniridia, colorblindness, corneal dystrophies, glaucoma, keratoconus, Leber congenital amaurosis, night blindness, retinitis pigmentosa and retinoblastoma, to name just a few.

Is Alagille syndrome fatal?
Intracranial bleeding (bleeding within the skull) is the most dangerous central nervous system complication of Alagille syndrome and is a major cause of morbidity and mortality. It occurs in approximately 15 percent of people with AGS, and in 30 to 50 percent of these events the bleed is fatal.
Can low bp cause blindness?
Blood pressure may change relative to the eye pressure and the normal flow of blood is reduced. If the optic nerve’s nutrient and oxygen supply is cut off, nerve tissue is damaged and lost, resulting in vision loss.
What is hereditary retinal dystrophy?
Retinal dystrophies are a group of rare diseases that damage the retina, the light-sensitive layer in the back of your eye. The retina sends signals to your brain so that you can see. Inherited means the condition runs in families. Often these diseases damage rods and cones in the retina.
Is Keratoconus inherited?
In most cases, keratoconus is not inherited and occurs in individuals with no family history of the disorder. The condition can also occur in families. In some cases, keratoconus is inherited in an autosomal dominant pattern , which means one copy of the altered gene in each cell is sufficient to cause the disorder.
What percent of all blindness is caused by eye diseases?
Vision impairments in people younger than age 40 are mainly caused by refractive errors, which affect 25% of children and adolescents, and accidental eye injury. Approximately 1 million eye injuries occur each year, and 90% of these injuries are preventable. More than half (52%) of all patients treated for eye injuries are between ages 18 and
