3结语
总之,虽有些报道认为NTG不予治疗的自然病程有很大的可变性,有些病情进展明显,而另外有些却可能静止,但对于NTG的病变发展,现仍多数认为是几种机制的共同作用,仍要求尽可能的降低30%以上的眼压,以达到NTG患者的靶眼压水平,减少因眼压造成的视神经损害,保护视功能。同时,因在眼压控制后,部分NTG患者的视神经萎缩仍继续发展,视野进行性缺失,增加眼血流和保护视神经也成为研究的热点。钙通道拮抗剂的应用对改善NTG患者的血循环有益。而前列腺素类制剂在拥有显著降眼压效果的同时,能改善视神经血流,其对NTG患者视功能保护的双重作用正日益得到关注。与此同时,对视神经保护治疗的研究亦日益深入。大量的中药提取物,如灯盏细辛,川芎嗪,复方樟柳碱,刺五加等,被应用于青光眼视神经保护的治疗中。通过降眼压、改善血循环和神经保护等多方面的综合治疗,保护NTG患者的视功能,提高NTG患者的生活质量将有更好的前景。
