A 59-year-old white man without ocular symptoms presented for annual follow-up of bilateral choroidal nevi (Figure 1A and B). Ten years before this visit, he had undergone complete wide excision of a cutaneous melanoma of the left forearm, along with a negative biopsy of sentinel lymph nodes. One year before the visit, he had developed a left axillary mass; a biopsy was positive for melanoma. He had received 4 infusions of 240 mg of nivolumab at 2-week intervals, after which the drug was discontinued because of elevated liver function test results, hypothyroidism, xerostomia, and dizziness. He started taking levothyroxine and continued taking aspirin, atenolol, and atorvastatin.
