Can keloid injections cause blindness?

I had septoplasty and tip only rhinoplasty in July 2018. I had some swelling the two years after that went away until 2024 after I started accutane in 2020. In 2024 my nose began swelling a lot mainly on one side. Finally in fall 2025 I got a keloid injection and my Nose was perfect for 8 months. When it got hot out, not sure why, the swelling returned. However it’s not nearly as bad as it was and is very close to just right. I am going back on accutane for my back acne in two weeks and wonder if this might correct the situation again. I am open to another keloid but just learned about the risk of blindness. Is that only with an injector who isn’t skilled or are you risking that every time you get a keloid injection? I will definitely not do it again if that’s the case, that’s not worth it.
