Ethambutol

I know there has been some threads about Ethambutol. I have been on 1200 mg 3xs a week along with Azithromycin and Rifabutin for the last year and a half.
However, after seeing an eye specialist he got me alittle worried about the toxicity of Ethambutol. I have now been off it 2 weeks now and have to make a decision about whether to go back on it or not. My lungs or my eyes? I feel like I may have to sacrifice one over the other. I am being referred to National Jewish because my last bronchoscopy showed I was refractory(mac still there).
My ID said I could maybe go on clofazamine(?) instead.
Sorry for long winded but has anyone had color blindness or worse with Ethambutol and has anyone been on the Clofazamine(it was a leprosy drug and I think you can only get it at Natl Jewish), Thank you!
