摘　　要：目的研究原发性闭角型青光眼（primaryangle—Closureglaucoma，PACG）的解剖结构特征。方法对正常眼、急性PACG和慢性PACG进行A超测量（包括前房深度、晶体厚度、玻璃体腔长度和眼轴长度）及角膜直径、角膜曲率的测量，比较3组测量参数有无差异。结果正常眼与PACG组角膜直径、角膜曲率、前房深度、晶体厚度、眼轴长度、以及晶体相对位置差异均具有统计学意义。急性PACG比慢性PACG前房更浅、玻璃体腔长度及眼轴更短。结论PACG在解剖上存在角膜直径较小、角膜曲率较大、前房深度较浅、晶状体较厚、眼轴较短、晶状体相对位置靠前等特点。Objective To study the biologic characteristics of the patients with primary angle-closure glaucoma （PACG）. Methods Biologic structure, including the anterior chamber depth, lens thiclmess, length of vitreous and axial length, were measured in 66 eyes eyes of normal controls by A-mode ultrasonic scanning measured. All mean values were analyzed. Results with acute PACG, 31 eyes with chronic PACG and 81 The diameter of cornea and corneal curvature was also There were significant differences between eyes with PACG and normal eyes in all items. Acute PACG had the shallowest anterior chamber, had the shortest vitreous and axial length： Conclusions The PACG eyes had a smaller cornea, larger corneal curvature, shallower anterior chamber depth, thicker lens thickness, shorter axial length and more forward relative location of lens.
