Daratumumab-induced transient myopic shift

Purpose: To describe an unprecedented case of transient myopic shift induced by a chemotherapeutic agent, daratumumab. Observations: A 43-year-old emmetropic female with multiple myeloma experienced sudden onset of myopic shift during her first intravenous dose of daratumumab, an increasingly common FDA-approved chemotherapeutic agent. Her myopia was corrected with -4D lenses in both eyes, and the patient reports cessation of symptoms and disuse of lenses after two days. Conclusions and importance: A number of medications have been documented to induce transitory myopic shift, and this report now includes daratumumab among such agents. Further clinical findings regarding the mechanism and frequency of daratumumab-induced myopic shift are needed to further develop our understanding of its tangential effect on the eye.
