Colours, they really do make our world don’t they? If you ask me, there is no greater sorrow than not being able to see the wonderful colours that make our world what it is. Just happened to catch an article on a cure for blindness today and it genuinely made me happy. The report talked about how scientists are on the verge of finding a permanent cure for blindness using some sort of new chemical.
Its great to know that scientists are actually trying to help humans rather than creating bombs that can wipe out entire towns. This new breakthrough in the treatment of blindness is thanks to a special chemical which when injected into a defective eye increases sensitivity of nerves thereby helping the person see.
Scientists used the chemical on congenitally blind mice and partially restored their vision. The testing was carried out on mice that were blind by birth. After the mice were injected with the compound, the rodents showed sensitivity to light which is a definite sign of improvement. There is still a long way to go before these chemicals can be used on humans but it’s a start nonetheless.
Scientists call this new wonder chemical AAQ and claims that it is much more effective than electronic chip or gene therapy treatments. The greatest advantage being that the chemical can be customised as per the severity of a patients’ blindness. The dosage can be varied and even used with other medications making it ideal for people of all ages.
The current versions of AAQ chemicals can only activate hyper sensitivity of neurons in the eyes for about a couple of hours but newer improved variants could give patients longer hours of sight. In the future, the chemical composition could be altered to may be make a permanent cure. Let’s keep our fingers crossed and hope that the cure will be ready in the coming few years.
