Choroid metastasis from nasopharyngeal carcinoma.

A case of choroid metastasis from nasopharyngeal carcinoma (NPC) is presented. If loss of vision in patients with NPC is not associated with proptosis or weakness of the extra-ocular eye muscles after radiotherapy, investigations to exclude choroid metastasis should be carried out. Choroid metastasis, in contrast to the more common causes of loss of vision in such a situation, radiation retinopathy and optic neuropathy, is amenable to treatment to prevent irreversible blindness and enucleation for intractable glaucoma pain.
