Does anyone have side effects, like eye damage, from Ethambutol?

Hi. I am Greg and have been taking the big 3 since March 2024, first at three times a week then daily since last September. About 2 weeks ago I started having vision problems in my left eye. It's like there is a constant glare in my vision. I went to an eye doctor who has been monitoring my vision but he couldn't find anything wrong but he referred me to another ophthalmologist specializing in toxicity. Was your eye problem like mine?

@nancysh Hello Nancy,
Yes, I agree, as a person who depends on her vision for everything, I was very concerned about ethambutol. When I had my pre-medication eye appointment with my ophthalmologist, I expressed my concern. She told me she monitors people taking ethambutol VERY closely, with a thorough baseline exam, then at 3 months, and every 6 months after that. In over 30 years, she said she had only 2 patients with a problem, even though it is used a lot in our community because we have a large immigrant population prone to TB (the other main use for the med.) She told me to stop the medication and call immediately if I had changes in vision or eye pain, and she would see me right away - I trusted her, and that set my mind at ease. I took ethambutol for over 18 month, 6 months of that was daily, and did not have an issue.
Remember, all drugs, even "safe" over-the-counter meds like antacids, can have side effects. It is a matter of deciding whether the benefit of treatment outweighs the risk.
Have you scheduled an eye exam?
