放射性视网膜病变(RR)是肿瘤患者在接受放射性治疗过程中发生的一种慢性进展性视网膜血管病变,多见于头颈部尤其是眼部肿瘤放射治疗后,其发生的概率以及严重程度受放射治疗的部位,放射剂量,以及眼部及全身因素的影响。RR的基本病理改变是血管内皮细胞的损伤,其可导致黄斑病变并严重影响患者视力。RR的干预方法主要包括预防和治疗,前者能有效减少RR的发生。玻璃体腔注射抗血管内皮生长因子(VEGF)药物是RR的一线治疗方法,激素治疗、激光光凝治疗等可作为补充。文章就RR的危险因素,发病机制,临床表现以及诊疗方法进行综述,旨在加强对RR的认识并总结近年来RR相关的研究进展。

[Abstract]
Radiation retinopathy(RR)is a chronic and progressive retinal vascular disease that occurs during radiotherapy for tumors. It is commonly seen after radiotherapy for head and neck tumors, especially those close to the eye. The incidence and severity of RR are influenced by risk factors such as radiation location, radiation type, and radiation dose. The basic pathological change of RR is the damage to vascular endothelial cells which could lead to maculopathy and subsequent vision loss. The interventions for RR include prophylaxis and treatment. Prophylaxis has been proved effective for reducing the occurrence of RR. Intravitreal injection of anti-vascular endothelial growth factor(VEGF)agents was the first-line therapy for treating RR, and corticosteroids and laser photocoagulation could serve as supplements. This article reviewed the risk factors, pathogenesis, clinical manifestations, and diagnostic and treatment methods of RR, aiming to enhance the understanding of RR and summarize the recent advances in RR.
