Quinine toxicity identified after 40 years

Abstract

This brief report describes a case of suspected ocular quinine toxicity. Most case reports of quinine toxicity have detailed descriptions of the acute clinical picture, laboratory results, electrodiagnostic findings, and patients’ progress. In this case, such detail is not possible since the patient presented to our unit about 40 years after the incidence of suspected quinine toxicity. The late clinical picture of this case is nonspecific, so it was only after an electrodiagnostic test and detailed drug history that the presumptive diagnosis of ocular quinine toxicity was made retrospectively. This case illustrates that a detailed drug history is important in ophthalmology.
