The 21-year-old, who goes under the pseudonym Wu Xiaojing, was a hardcore fan of popular multiplayer smartphone game Honour of Kings and ended up in the hospital after a 24-hour gaming marathon left her blind in one eye.

She was diagnosed the following day with Retinal Artery Occlusion (RAO) – usually more common in elderly patients – which occurs when there is a blockage in one of the arteries that carry blood to the retina.
