Welcome to Mayo Connect, and to our MAC & Bronchiectasis support group. Many of us have been on the antibiotics with little to no impact on our vision or hearing. My pulmonologist had me get baseline vision and hearing tests done as I started the meds, then every 6 months thereafter. I did experience some increase in existing tinnitus, but no loss of hearing or vision.
If you begin to have vision issues, the medication Ethambutol will be stopped. According to my ophthalmologist, this happens in less than 10% of cases.
If you have hearing issues, the other two medications may be replaced. I am not familiar with the statistics on how often either occurs.
