Cancer associated retinopathy (CAR) is an uncommon paraneoplastic syndrome associated with epithelial neoplasm. Ocular symptoms of this syndrome are varied.
A 40-year-old man with an existing smoking history noticed a bilateral visual loss.Fundus examination showed a bilateral vitreous hemorrhage.In the left eye, there were narrowed retinal arterioles and peripapillary neovessels. An X-ray chest revealed a lung lesion which on biopsy proved to be a bronchial squamous cell carcinoma. After conducting several explorations,we have diagnosed CAR.
Vitreous hemorrhage is one of the symptoms of CAR. Thus, systems review, searching for an extraocular cancer, X-ray chest and ERG are recommended in this case.
癌症相关性视网膜病变（CAR）是一种与上皮性肿瘤相关的罕见副肿瘤综合征。该综合征的眼部症状多种多样。
一名有吸烟史的40岁男性出现双侧视力丧失。眼底检查显示双侧玻璃体出血。左眼视网膜动脉变窄，视乳头周围有新生血管。胸部X线检查发现肺部病变，活检证实为支气管鳞状细胞癌。经过多次检查，我们诊断为CAR。
玻璃体出血是CAR的症状之一。因此，对于这种情况，建议进行系统检查，寻找眼外癌，进行胸部X线检查和视网膜电图检查。
