Bilateral subfoveal serous detachment following Cisplatin chemotherapy

A 74-year-old gentleman with a background of metastatic pancreatic neuroendocrine tumour on combination chemotherapy of Cisplatin and Etoposide presented with a 3-week history of bilateral visual loss. Snellen visual acuity was right 6/9 and left 6/60. Fundus examination revealed clear media with isolated macular oedema in both eyes. Optical coherence tomography of the maculae showed localised bilateral subfoveal serous detachments. Cisplatin was thought to be the causative agent and was withheld following discussion with the treating Oncology team. Eight weeks after withholding Cisplatin, his vision improved with complete resolution of the subretinal fluid. To the authors' knowledge, this is the first report to have illustrated bilateral subfoveal serous detachment caused by Cisplatin which resolved completely with cessation of offending drug.
