Sam Fox has claimed she was "nearly blinded" in a prank by her Celebrity Big Brother housemate Stephen Bear.
The former pin up said Bear dislodged her contact lens after spraying water in her eye - leaving her unable to open it for four hours.
"I had to see a medic and keep an eye patch on for half a day - it was horrible," she said.
But the scenes - which hadn't been aired - have now been cut from the show prompting viewers to ask why.
Fans on Twitter asked whether it had not been shown to protect Bear, who is a favourite to win the show and is currently on his final warning.
Stuart Osmond tweeted, "So there you go. Bear hits Sam in the eye, so she had to see a medic, yet we didn't see that tonight. Proof it's fixed for Bear to win."
Another asked: "Why has big brother not shown #cbb the eye incident though? Why are they protecting @stephen--bear hhhmm keeping him in ey #ratingsMaybe?"
A third Twitter user wrote: "So what else haven't they been showing beside Bear really hurting @SamFoxCom eye? Obviously quite a lot! I wonder why ... "
Others asked why it had not been enough to get him booted out the house.
Corey Seville tweeted: "Any reason why the Sam/Bear eye incident wasn't shown? Did he get a warning? Why wasn't he thrown out?"
@LadyBfothergill added: "Bear hurting Sam's eye, wouldn't that constitute a 3rd and final warning? Better not show it otherwise they'd have to remove him #CBB #Fix."
A Channel 5 spokeswoman confirmed medics were called but said the footage was not aired on Tuesday as it was a shorter show due to the double eviction.
She added there were no plans to air the footage.
