简介：结膜松弛症是老年人常见眼病，但一直为国内眼科医师所忽视，易造成误诊、漏诊。上海中医药大学附属普陀医院经过十几年的探索，对结膜松弛症的诊疗技术进行了系统研究，已经形成规范的诊疗方案。特举办国家级Ⅰ类（6分）继续教育项目“结膜松弛症的发病机制及手术治疗”（项目编号：20110702052）学习班，并系统演示结膜松弛症手术治疗录像、现场观摩手术。

简介：甲状腺相关性眼病是一种与甲状腺疾病相关的器官特异性自身免疫性疾病，其病理表现为大量糖胺聚糖堆积，导致眼球突出，上睑挛缩，复视等临床表现。根据疾病活动性，可以进行活动期与静止期的分类。目前甲状腺相关性眼病活动性评价主要依据患者的症状和体征，以及影像学检查。细胞因子、黏附分子及糖胺聚糖的研究，为甲状腺相关性眼病活动性的客观评价提供了广阔的前景，现做一综述。
