Abstract. Purpose:To report a case of orbital apex syndrome due to metastasis of prostate carcinoma. Case:A 48-year-old male presented with impaired vision in the left eye since 6 weeks before. His corrected visual acuity was 1.2 right and 0.01 left. Funduscopic findings were inconspicuous. The visual field in the left eye was defective except the superior periphery. Clinical Course:He was tentatively diagnosed with retrobulbar neuritis. Six days after systemic corticosteroid, his left visual acuity lost light perception associated with paralysis of adduction and hypesthesia in the left forehead. Magnetic resonance imaging(MRI)showed a tumor of 2cm in diameter in the left orbital apex. Systemic studies led to detection of postate cancer with systemic bone metastasis. The orbital tumor disappeared after 10 months of hormonal and chemotherapy. The left eye failed to recover from visual loss. Conclusion:Extraocular malignancy may induce findings simulating retrobulbar optic neuritis.
