The ocular manifestations of EON include painless loss of central vision and cecocentral scotomas in the visual field.Patient concerns:A 75-year-old Chinese Han man suffered from this rare ocular disorder because he took ethambutol for about 8 months.Diagnoses:He was diagnosed as EON based on series of ophthalmic examinations performed.Interventions:Since he has stopped taking this drug for 3 months, we just offered some neurotrophic agents to him.Outcomes:One month later, he came back for return visit. The ophthalmic examinations indicated recovery of the visual function very well.Lessons:The EON is a reversible optic neuropathy if the ocular toxicity is monitored closely among the tuberculosis patients that take ethambutol.
