Giving sight to the blind
Visual impairment is still rather rampant, according to the World Health Organization (WHO).
Some 285 million people worldwide are
considered visually impaired, and 39 million of them are blind.
Thankfully, 80 percent of all visual impairment can now be treated or cured,
except in cases of total loss of sight, particularly those due to severe retinal degeneration.
But what if it’s possible to restore visual function to blind patients? Laboratory tests in the University of Oxford demonstrate how this may be
possible.
In a study published in the journal of the Proceedings of the National Academy of Sciences (PNAS), the Oxford researchers led by
Samantha de Silva showed how it’s possible to restore the sight of people suffering from blindness previously considered untreatable.
