犬青光眼与干眼症：眼睛发红不是"上火"，可能是致盲急症

青光眼在数十小时到数天内就可能造成不可逆失明，干眼症则常被长期误当结膜炎。这篇按眼科手术综述与干眼诊断研究，讲清识别与就诊时机。
一、青光眼：小时级的视力争夺战
信号：
- 眼球发红、角膜发白浑浊、眼睛看起来变大；
- 瞳孔散大或对光反应迟钝、眯眼流泪；
- 精神沉郁、食欲下降（疼痛表现）、用头蹭东西。
青光眼是眼压升高导致的视神经损伤，其外科处理（包括滤过性手术与睫状体破坏性手术、终末期处置）在专科综述中有系统总结[1][2]。核心事实是：视力损伤不可逆，时间就是视力——出现上述组合，当天就诊。
二、干眼症（KCS）：被长期误判的"慢性红眼"
- 反复黏稠脓性眼分泌物、眼睛发红；
- 角膜失去光泽、血管新生、色素沉着（长期）；
- 眨眼频繁、怕光。
诊断靠泪液量测定（STT），研究指出单纯依靠症状容易漏诊或误判，需要规范测定并结合其他泪膜指标[3]。（另有一类"神经性干眼症"，表现为单侧泪液骤减，需排查神经因素。）

Canine glaucoma is a common cause of vision loss associated with raised intraocular pressure, and leads to damage of the retina and optic nerve head. In most cases, medical treatment alone cannot provide long-term management of intraocular pressure control and preservation of vision. Surgical intervention is usually recommended to either decrease aqueous humor production, or increase its outflow. Among the current available procedures, filtering techniques are aimed at increasing aqueous humor outflow. Proper surgical timing and a combination of cyclodestructive and filtering procedures have been recently suggested to improve the long-term success of surgical treatment in dogs. Bleb fibrosis and surgical failure are still common occurrences in filtration surgery with relapse of glaucoma and vision loss. End stage procedures, such as enucleation, evisceration with intrascleral prosthesis, and chemical ablation of the ciliary bodies are then recommended to address chronic discomfort in buphthalmic and blind eyes.
