Lzd, E; rarely H, Eto or Pto
This adverse effect is typically due to Lzd and E.
Symptoms include loss of red-green colour distinction, reduced visual acuity and central scotoma. Loss of red-green colour distinction is the first sign. In this case, stop the suspect drug immediately and permanently.
Symptoms are usually reversible after discontinuation of the drug, but optic neuritis due to Lzd may be irreversible.
