Cancer associated retinopathy with periphlebitis and bilateral vitreous hemorrhage
Introduction:
Cancer associated retinopathy (CAR) is an uncommon paraneoplastic syndrome associated with epithelial neoplasm. Ocular symptoms of this syndrome are varied.
Case Report:
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.
Conclusion:
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.
