慢性青光眼（二）
视野检查对青光眼的诊断有重要价值。因为它代表了视神经的损伤。临床常见视野缺损类型有：视阈值普遍降低、弓形缺损、鼻侧阶梯、垂直阶梯、颞侧扇形缺损、中心及颞侧岛状视野缺损。通过上述检查，我们可以诊断青光眼，但在开始治疗前还应确定青光眼的类型。首先检查前房角，房角开放者为开角型青光眼，反之则为闭角型青光眼。通过房角检查，青光眼分类诊断仍有困难时，可查房水流畅系数（C值）。C值小于0.1为病理性，压畅比（Po/C）大于150为病理性，主要见于开角型青光眼。但需注意，闭角型青光眼反复发作后C值及压畅比也可异常。另外我们对一些疑似青光眼可选一些激发试验，以辅助诊断。并发症：
急性闭角青光眼，常合并恶心、呕吐、发热、寒战及便秘等，少数病人可有腹泻发生。慢性闭角青光眼，常伴有视蒙、虹视。本病最严重得并发症是失明。预防：
青光眼是老年人常见的一种眼病，也是最易造成失明的眼病之一。正常的眼球，经常保持一定的紧张度，这种紧张度是眼内容物对于眼球壁所加的压力而形成，医学上称为眼压。中国正常人的眼压在1.4～2.8千帕之间，眼内房水的产生和循环障碍是造成眼压升高引起青光眼的主要原因。青光眼病人的眼压，常常超过3千帕，有的高达10千帕以上。由于眼压过高，视神经和黄斑部受压迫而发生功能失常，于是引起视力减退、头痛、眼痛、视力模糊不清、看灯光周围有虹圈、眼球坚硬如石等，若不及时治疗，往往导致失明，所以加强预防，非常重要。魏氏中医眼科的辩证施治：
先要说明的是中医中药对于治疗慢性开角性青光眼疗效较好，像急性的闭角性的青光眼还是要选择西医治疗方案。任何疾病诊断是关键，找对正确的治疗方法，更是关键。中医药治疗青光眼目前主要以活血化瘀、益气、健脾、利水、祛风、滋补肝肾等诸法为主。对青光眼视功能损害的治疗，以活血化瘀为主，辅以其他治法如益气、利水等配合。现代医学也证明部分活血化瘀类中药具有扩张血管、增加血流量、改善视神经供血、增强视网膜血管和视神经的耐氧能力、降低血液粘稠度、改善轴浆流、清除缺血后再灌注产生的氧自由基等作用。通过以上治疗作用，提高视神经的兴奋性，使部分尚未造成不可逆损害的视神经恢复功能，从而提高患者的视功能。魏鸿友主任治疗本病有着四十多年的临床治疗经验，大量患者通过中医治疗获得满意证明了中医中药治疗慢性青光眼的优势！Service Box Type 1
