Purpose: We describe a case of bilateral angle closure glaucoma following the infusion of daratumumab, a monoclonal antibody used to treat relapsing multiple myeloma.

Methods: This is an interventional case report.

Results: A 59-year-old woman presented with bilateral angle closure glaucoma one day following her first infusion of daratumumab. B-scan echography showed ciliochoroidal effusions in both eyes. Cycloplegia was implemented given the suspicion for drug-induced angle closure, which resulted in prompt deepening of the anterior chambers and normalization of intraocular pressures. The ciliochoroidal effusions resolved 16 days following the cessation of daratumumab.

Conclusions: Daratumumab may be associated with drug-induced secondary angle closure glaucoma.
