Abstract
Introduction: Metastatic ciliary body tumor is a relatively rare tumor with a poor prognosis. Ciliary body tumors manifest as closed angle glaucoma, secondary glaucoma (phacomorphic glaucoma (PG), neovascular glaucoma), chronic uveitis, and cataract. The diverse manifestation of symptoms leads to diagnostic errors. Case presentation: This article presents a clinical case of a man aged 59 years with PG of the left eye. Ultrasound biomicroscopy revealed: a mushroom-shaped mass on the ciliary body penetrating toward the posterior chamber, with indistinct boundaries. Metastatic tumor of ciliary body had clinical manifestation as PG in this patient. Conclusion: All types of secondary glaucoma and acute attack of primary closed angle glaucoma should be carefully examined for intraocular tumor. Incorrect choice of treatment tactics for such patients can lead to common complications such as metastasis.
