再议原发性闭角型青光眼新分类

Comments on classification of primary angle-closure glaucoma

国际地域性和流行病学眼科学学会（ ISGEO）对PACG提出新的分类系统，给传统分类带来了新的理念和冲击。然而，两种分类历经多年临床实践后，仍给眼科临床医师带来不少困惑和尴尬。新分类显然有不少不适合中国国情的地方；按照国内传统分类和专家共识进行临床科研，则难以和国际接轨或被国际认可。有必要再议这些问题。开展国人自己的大规模、前瞻性、随机对照临床研究是解决这一问题的有效手段。

The new criteria to classify and diagnose primary angle-closure glaucoma （ PACG ） proposed by International Society Geographical＆amp;Epidemiological Ophthalmology （ ISGEO） brought about not only new concept but also huge impact on Chinese traditional classification established in 1987.The controversy between these two systems has baffled Chinese ophthalmologists in years of clinical practice .The new criteria obviously has some concepts not suitable and not practical for Chinese PACG patients .However , domestic studies based on traditional classification are not internationally valued or accepted .Chinese own evidence-based clinical trials are urgently needed to elucidate the pros and cons of two classification systems.
