Does linezolid harm vision?

Linezolid (Linezolid) may cause optic neuritis when used for a long time or at high doses. This is a serious side effect that may affect vision. Optic neuritis results from inhibition of mitochondrial function by linezolid. Patients may experience symptoms such as blurred vision, abnormal color vision, or visual field defects. Although this condition is relatively rare, it can significantly affect quality of life. Therefore, doctors often monitor patients' visual function while using linezolid, especially in patients treated long-term. Patients should note and regularly report any visual changes so that early action can be taken. To reduce the risk of optic neuritis, doctors typically adjust the dose of linezolid based on the patient's specific circumstances and needs, combined with the use of antioxidants or other supportive treatments when necessary. Overall, although linezolid may cause visual impairment, this risk can be clinically minimized with monitoring and appropriate management.
