泪囊炎和泪腺炎有什么区别?

来源:华人健康网 | 发布时间:2010-10-23 16:09:48 | www.chinesejk.com
泪囊炎是因沙眼、鼻窦炎、结核等原因引起鼻泪管阻塞、泪囊里泪液潴留并继发细菌感染所致。证见经常流泪及视物模糊、眼部烧灼感等,用手指压迫泪囊处,常有脓液或粘液由泪点流出。急性泪囊炎的泪囊区皮肤红肿、疼痛,数日后化脓穿破,可遗留瘘管。本病属中医学的“眦漏”、“漏睛”等病范畴。多因肝火风热或心火旺盛,或肾阴不足、虚火上炎而致。   泪腺炎由感染,不明原因的肉芽肿性病变或良性淋巴上皮病变引起泪腺炎性肿大。急性泪腺炎可分别或同时累及泪腺的睑叶或眶叶。睑叶的急性炎症表现为眶部疼痛,上睑水肿并可呈S形弯曲变形,耳前淋结肿大,触诊时可触及一个压痛的包块,结膜充血及水肿,有粘性分泌物。病程通常短暂,可自行缓解,但也可能化脓。慢性泪腺炎一般无疼痛,泪腺肿大,有上睑下垂,在眶外上缘下可触及较硬的包块,眼球可向内下偏位,向上、外看时可有复视,但眼球突出少见。
