脉络膜转移癌是一少见的眼部肿瘤,该病在眼科临床的发病率是1:130,000～150,000。1872年Perls 首先报告一例肺癌转移到脉络膜者,以后续有报道。鉴于此病少见,不易正确诊断,故脉络膜转移癌的发病率实际上较所知者为高。近年来随着放射技术的提高及抗癌新药的使用,癌疵患者的寿命因之延长,脉络膜转移癌的发病率较前有所增加。现结合国外文献就脉络膜转移癌的原发部位、转移途径、临床表现、病理改变、诊断、鉴别诊断、 Chorioretinal metastasis is a rare ocular tumor, the incidence of clinical disease in the eye is 1: 130 000 ~ 150 000. Perls first reported in 1872, a case of lung cancer metastasis to the choroid, and later reported. In view of the rare disease, not easy to correct diagnosis, so the incidence of choroidal cancer is actually higher than the known. In recent years, with the improvement of radiological techniques and the use of anticancer drugs, the lifespan of cancer patients is prolonged, and the incidence of choroidal metastasis has increased. Now combined with foreign literature on the primary site of choroidal metastasis, metastasis, clinical manifestations, pathological changes, diagnosis, differential diagnosis,
