Weird news - Woman regains sight due to injury after years

There are still many aspects of the human body and its various components that are not easily understood by doctors and medical science. From time to time, one comes across incidents that are sometimes seen to be miracles, where a medical practitioner is not able to logically and scientifically explain why something seems to happen; this does not necessarily mean that it was a miracle but that the level of understanding of medical science of what happened is not yet sufficient.
In the current case, it would seem that a miracle happened. A lady lost her eyesight 20 years back through a car accident and an injury to a spine in 1993. Then recently, she had a fall inside her house and hit her head, and then had to be hospitalized and had operations. And then after an operation, while coming to, she had a surprising observation; she was able to see again. The Doctor had no real reason as to why this happened; with a possible scientific reason being that a blood vessel supplying the brain had got blocked during the earlier accident and the recent one causing the blockage to get removed.

A 70-year-old woman in Florida who was been blind for over 20 years has regained her sight after falling over and hitting her head at her home, baffling her neurosurgeon who says it is a “true miracle”. Mary Ann Franco, gradually became blind after injuring her spine in a car accident in 1993. Then, more than two decades later, another accident and a subsequent operation appears to have led to the recovery of her sight, although doctors are still trying to work out how exactly this could have happened. “I was fully blind all I could see was blackness,” she told The Independent. “I was in my living room, going over to the door. My foot caught on a tile, and it flipped me. I hit my head in the back, and hit it on something else, maybe the fireplace,” she said.
