The mechanism of linezolid-induced optic neuropathy is not known, but may be due to mitochondrial toxicity from binding to mitochondrial 16S rRNA.27 Linezolid penetrates the central nervous system and eye well, which may lead to enhanced neurotoxicity.24,28 Withdrawal of linezolid and switching antibacterial therapy to another agent may aid recovery, although in some cases continuation of linezolid may be necessary to adequately treat certain infections.2 Baseline and periodic ophthalmologic examinations are recommended for patients receiving long-term linezolid treatment.4, Ethambutol: This drug, a first-line agent in the treatment and prevention of tuberculosis, causes numerous ocular adverse effects. The incidence of NAION cases of men using PDE-5 inhibitors worldwide is consistent with that of the general U.S. population.14 The World Health Organization (WHO) and the FDA have identified the association of NAION and PDE-5 inhibitors as “possible” causality.
