Abstract：
We present a case of diagnostic interest; we present the differential diagnosis and the complementary tests necessary to reach it, in addition to highlighting the importance of a correct collection of background and clinical history. A 54-year-old woman with a history of carcinoma of the floor of the mouth treated with radiotherapy and chemotherapy develops ischemic retinopathy. It was necessary to perform a systemic study and differential diagnosis with entities such as ocular ischemic syndrome and radiation retinopathy, due to the similarity in the clinical findings found. Radiation retinopathy should be ruled out in any patient with visual impairment and a history of radiotherapy treatment. A broad differential diagnosis and systemic study are required to rule out entities such as ocular ischemic syndrome and diabetic retinopathy, in addition to early treatment to avoid possible complications.
摘要：
我们提出了一个诊断兴趣的案例；我们提出了达到它所需的鉴别诊断和补充测试，除了强调正确收集背景和临床病史的重要性。一名54岁的女性，有接受放疗和化疗的口腔癌病史，出现缺血性视网膜病变。有必要对眼部缺血综合征和放射性视网膜病变等实体进行系统研究和鉴别诊断，由于临床发现的相似性。任何有视力障碍和放射治疗史的患者应排除放射性视网膜病变。需要广泛的鉴别诊断和系统研究，以排除诸如眼缺血综合征和糖尿病性视网膜病变等实体。除了早期治疗，以避免可能的并发症。
