Abstract:
Breast cancer-associated retinopathy (BCAR) is a paraneoplastic neurologic syndrome that results in progressive loss of vision and retinal degeneration. The morbidity rate of cancer-associated retinopathy among breast cancer patients is reportedly 0.68%. However, to date, few studies have focused on BCAR. The ocular symptoms of breast cancer are often misdiagnosed by some physicians as side effects of drugs, diabetic retinopathy, or senile cataract. Early diagnosis and treatment of BCAR improve the quality of life of patients. This article reviews the etiology, pathogenesis, morbidity, clinical manifestations, diagnosis, treatment, and prognosis of BCAR.
