5 展望
青光眼是位列全球第二的不可逆致盲性眼病。据世界卫生组织与Qurgley的资料提示,至2000年,全球约有6 680万患者罹患原发性开角型青光眼或原发性闭角型青光眼,600万患者罹患继发性青光眼。其中约有670万患者因青光眼致盲[43]。
青光眼视神经损害的机制至今仍不十分明确,传统的机械压力学说与缺血学说都无法完全解释青光眼的视神经损害,但眼压不是青光眼视神经损害发生的惟一危险因素已被广泛认可。如何能减缓视神经损害是青光眼治疗的重点。目前青光眼的治疗已经不单单局限于对眼压的控制,视神经保护的研究为青光眼的治疗开辟了新的途径。目前的多数研究均证实青光眼和AD之间存在相关性,但也有研究持有不同的观点。青光眼和AD是否存在相同的发病机制,它们是否是同一疾病的不同表现仍然需要更多的研究来回答。对青光眼与AD等神经元变性疾病相关性的研究为进一步认识青光眼视神经损害的发病机制开辟了方向。更好得认识青光眼与AD等疾病的相关性,可以为青光眼视神经保护的治疗注入新鲜血液。
