Visual Recovery Following Linezolid Cessation in an MDR-TB Patient: Detailed Case Analysis

Area of Science:

• Ophthalmology
• Infectious Diseases
• Pharmacology

Background:

• Multidrug-resistant tuberculosis (MDR-TB) requires complex treatment regimens.
• Linezolid is a crucial antibiotic for MDR-TB but carries risks of ocular toxicity.
• Optic neuropathy is a known adverse effect of linezolid, typically manifesting as vision loss.

Observation:

• A patient with MDR-TB developed progressive visual disturbances during linezolid treatment.
• Ophthalmologic examinations confirmed optic neuropathy, ruling out intracranial pathology.
• Vision improved significantly only after linezolid discontinuation, despite other treatments.

Findings:

• Linezolid-induced optic neuropathy can occur with prolonged MDR-TB treatment.
• The condition is potentially reversible upon cessation of linezolid therapy.
• Early detection and intervention are critical to prevent permanent vision impairment.

Implications:

• Vigilant ophthalmologic monitoring is essential for patients on long-term linezolid.
• Timely discontinuation of linezolid can preserve vision in cases of optic neuropathy.
• Understanding linezolid's ocular toxicity aids in managing MDR-TB treatment strategies.
