Injection could restore sight to blind

Simple injection could restore sight to blind

A new injection could be the answer to restoring sight to hundreds of thousands of blind people.

The injection of human genes goes straight into the eye’s retina and has already proved a success story with three patients who had an inherited blind condition finding their sight drastically improve within a month.

The three patients in their twenties had a condition known as Leber’s congenital amaurosis which means faulty genes stop cells in the retina from working. Up until now there has been no cure for the condition.

The advancement has led scientists to believe healthy genes could help those who suffer with other genetic eye conditions, such as age-related macular degeneration, which effects 400,000 people in the UK.

Experts say the technique could be available within two years to treat a variety of inherited diseases of the retina.
