Michael Bisping vs. Vitor Belfort
Michael Bisping went through hell due to a detached retina he suffered from a head kick knockout against Vitor Belfort back in 2013.
Against his better judgement, Bisping kept the injury to himself, fearing it could end his career, and would go on to beat Alan Belcher next time out despite his impaired vision.
However, Bisping’s right eye eventually got so bad that he couldn’t see his hand in front of his face and so had to undergo surgery.
Later that year he suffered another retina detachment and this time had oil injected into the eye to preserve it while he continued his fighting career.
Bisping would have five operations on the eye in total, but revealed after retiring that he had been fighting with only 20/200 vision in that eye (essentially legally blind), making it even more remarkable that he won the middleweight title and successfully defend it during that period.
As fate would have it, Bisping experienced a vitreous detachment in his other eye following a fight with Kelvin Gastelum in 2017, at which point he finally decided he could risk his sight no longer and retired.
Nowadays Bisping wears a prosthetic in his right eye due to it having been permanently disfigured.
