Artificial retinas give blind patients ability to see light and shapes

By George Dvorsky

Two British men who were completely blind for years have regained some of their vision, after undergoing surgery to fit eye implants, according to the BBC.

This pioneering treatment is at an early stage of development, but it marks an important step forward in an effort to help those who have lost their sight from a condition known as retinitis pigmentosa.

The breakthrough was part of a clinical trial carried out at the Oxford Eye Hospital and King's College Hospital in London by Robert MacLaren and and Tim Jackson. Their work focuses on a previously untreatable condition known as retinitis pigmentosa (RP) - a type of inherited progressive retinal dystrophy in which abnormalities of the photoreceptors (rods and cones) or the retinal pigment epithelium (RPE) of the retina lead to progressive visual loss. The condition happens when the photoreceptor cells at the back of the eye gradually cease to function. MORE HERE >>>
