Purpose To report two cases of metastatic neuroendocrine tumors masquerading as primary ocular disease. Observations Case 1 is a 38-year-old man who was referred with subacute onset diplopia and fluctuating ptosis suggestive of myasthenia gravis. Case 2 is a 21-year-old man who presented with blurry vision and was found to have a pigmented ciliary body mass and retinal detachment suggestive of uveal melanoma. Both patients were ultimately diagnosed with metastatic neuroendocrine tumors. Conclusions and Importance Neuroendocrine tumors, though rare and infrequently metastatic to the eye and orbit, can initially present with ocular signs. A broad differential and careful consideration of ocular and systemic symptoms are critical in such challenging cases.
