Two Cases of Choroidal Metastasis from Breast Cancer.

We report two cases of choroidal metastasis from breast cancer. The first case was a 41-year-old woman with loss of her right upper visual area in whom right breast cancer accompained by lung and choroidal metastases were detected simultaneousyl. She died without having received radiation therapy for the affected eye 6 months after mastectomy and oophorectomy. The second case was a 34-year-old woman in whom choroidal metastasis causing right visual disturbance was diagnosed 3 years after mastectomy for breast cancer. She received radiation therapy following oophorectomy and her visual acuity completely recovered. She dies 7 months later. Radiation therapy improved her quality of life despite her short survival, because her visual acuity was maintained until death. In general, the life span of patients with choroidal metastases is short because of multiple organ metastases, but to obtain a better quality of life, active treatment of the affected eye is necessary.
