青光眼是一组病理性眼压升高导致的以视力下降、视神经萎缩和视野缺损为特征的疾病。正常人的眼压稳定在一定范围内,可以维持眼球的正常形态。正常眼压范围是10mmHg~21mmHg。眼压作为一项生理指标和血压一样,是波动的。多数人在凌晨最高,在深夜较低。但它的波动往往不会对视神经造成损害,波动值不会超过5mmHg。有些类型的青光眼早期没有明显症状,通常需要观察眼压波动来提供诊断依据,进行早期干预治疗。

眼压不仅是青光眼的诊断依据,同时还是判断治疗青光眼疗效与青光眼患者随访的重要指标。降低眼压减少视神经损害是治疗青光眼的主要目的:对于青光眼患者来说,不是把眼压降至正常范围就可以了,而是要因人而异;对于青光眼视神经无明显损伤者,眼压降至正常范围即可;对于青光眼视神经进展期损伤患者,降至15mmHg以下,视神经损伤不再继续;对于青光眼视神经损害中晚期患者,降至12mmHg以下,才有可能视野受损不再进展,特别是晚期患者往往眼压降至11mmHg以下更安全。可见,眼压的监测对于青光眼患者至关重要。

多数青光眼患者的病程缓慢,即使眼压升高,往往也感觉不到。只有定期随诊复查眼压才可以发现问题,便于医生及时调整治疗方案。一定要像监测血压一样监测眼压,花费虽小意义却很大。
