[Necrotizing blepharitis following captopril-induced agranulocytosis].

A case of necrotizing blepharitis due to a side-effect of captopril medication is described. Blepharitis was the first clinical sign of drug-induced agranulocytosis. The history of drug intake as part of the anamnesis was the most important diagnostic tool for the ophthalmologist since the course of agranulocytotic blepharitis depends on the elimination of the drug.
