“An eye drop tested on dogs suggests that cataracts, the most common cause of blindness in humans, could one day be cured without surgery, a study has said.
A naturally-occurring molecule called lanosterol, administered with an eye dropper, shrank canine cataracts, a team of scientists reported in Nature.
Currently the only treatment available for the debilitating growths, which affect tens of millions of people worldwide, is going under the knife.
While surgery is generally simple and safe, the number of people who need it is set to double in the next 20 years as populations age. And for many, it remains prohibitively costly.
The chain of research leading to the potential cure began with two children — patients of lead researcher Kang Zhang of Sun Yat-sen University in Guangzhou, China — from families beset with a congenital, or inherited, form of the condition.”
