A novel agent for myeloma causing toxic keratopathy, belantamab mafodotin: a case report and literature review

Belantamabe-mafodotina, um novo agente para mieloma, causando ceratopatia tóxica: relato de caso e revisão da literatura

ABSTRACT

A 60-year-old-male with refractory relapsed multiple myeloma presented with redness, pain, foreign body sensation, and blurred vision in both eyes that gradually increased after his third belantamab mafotodin infusion. Biomicroscopy revealed bilateral microcyst-like epithelial changes and epithelial crystal-like deposits, whereas in vivo confocal microscopy revealed intraepithelial and subepithelial hyperreflective deposits in corneal epithelium. Belantamab mafodotin therapy was discontinued for seven weeks due to corneal toxicity, which cleared progressively. We aim to demonstrate belantamab mafodotin-related corneal toxicity that may be detected using slit lamp and in vivo confocal biomicroscopy.
