Indications Linezolid is a synthetic oxazolidinone antimicrobial drug. Administration Linezolid is available in tablets, suspension, and injection.

Contraindications Do not use within two weeks color vision deficiency test MAO inhibitors, e. Toxicity Toxicity is rare, and there is no antidote for linezolid. Enhancing Healthcare Team Outcomes The healthcare team, e.

Correct diagnosis and discontinuation of the drug resulted in significant recovery of vision. Medical history included chronic diabetes mellitus, below self harm cuts knee amputation color vision deficiency test the right Meclizine Hydrochloride (Meclizine Hydrochloride Tablets)- FDA, hypertension, sinusitis with nasal allergies, and asthma.

Several years earlier he had fractured his left ankle and developed osteomyelitis from methicillin resistant Staphylococcus.

He had received linezolid 600 mg by mouth twice a day for 12 months, then once daily for 44 months. He was a non-smoker and consumed less than one unit of alcohol per week. No relative afferent pupillary defect was present.

Intraocular pressures were 16 mm Hg in both eyes. Fundus examination revealed temporal optic nerve pallor with a corresponding temporal nerve fibre layer defect more evident in the right eye (fig 1) and a normal macula in both eyes.

Humphrey visual field testing (full field 120 point screen) revealed central scotomas in both eyes (fig 2). Fluorescein angiography revealed a normal macula without staining of the peripapillary region in both eyes (not shown). Full field scotopic and photopic electroretinography demonstrated a normal amplitude and latency in both eyes, as expected given the small central scotoma.

Bottom, 3 months after discontinuing linezolid there is temporal pallor and nerve fibre layer defects in the right eye (lower left), again with no definite changes in the left eye (lower right).

Humphrey full field 120. Top left and right, left eye and right eye, respectively, demonstrating central scotomas at presentation. Bottom left and right, left eye and right eye, respectively, showing improvement in the central scotomas 3 months after discontinuation of linezolid.

Linezolid was discontinued and the patient noted subjective visual improvement within several weeks. Toxic optic neuropathy has been associated with numerous compounds, including exposure to ethylene glycol, methanol, isoniazid, ethambutol, and fluoroquinolone, and deficiency of vitamin B12, folate, and thiamine. It is important for ophthalmologists to perform a complete review of systems and elicit a history of prescription and non-prescription medication use.

Awareness of the potential for linezolid induced optic neuropathy is important since drug withdrawal can lead to visual recovery.
