Radiation to the optic disc carries a significant risk of injuring the optic nerve, leading to worsening of vision. Alternative treatment approaches are needed. We present a patient with large-cell neuroendocrine carcinoma with metastasis to the peripapillary retina who was treated with intravitreal topotecan and with intravitreal aflibercept.
