Cystoid macular edema (CME) is a rare adverse event induced by taxane-based chemotherapy. Here, we describe the case of a 71-year-old man who developed bilateral CME during treatment with nab-paclitaxel (nab-PTX) for unresectable pancreatic cancer. Two months after drug discontinuation, his vision improved, and there was significant reduction in the CME on optical coherence tomography. CME is an adverse event that can be treated with the early withdrawal of nab-PTX. Oncologists who use nab-PTX should be aware of this adverse event for timely patient referral to an ophthalmologist and appropriate treatment that would enable the preservation of the patient's visual acuity.
