RCOphth Statement on Ethambutol Toxicity

  • 31 Oct 2017

NHS Improvement has highlighted two recent incidents of severe visual loss due to delayed diagnosis of optic neuropathy from ethambutol.

In 2015, 5758 cases of tuberculosis were notified in England and ethambutol is frequently prescribed in its initial phase of treatment.

Although ethambutol optic neuropathy is rare, members are strongly reminded of the possibility of this cause of preventable sight loss and to ensure that current guidance is followed.
