目的：本研究的目的是分析原发性闭角病（PACD）患者在透镜摘除前的人口统计学和角膜散光分布。方法：术前对PACD患者进行部分相干干涉测量。记录人口统计学和生物统计学数据，包括角膜散光和角膜曲率（K）。结果：808例1001眼，平均年龄67.66±9.07岁，眼轴平均22.55± 0.89mm。平均角膜散光为1.08± 0.78D。角膜散光0.25 ~ 1.25D者占66.50%，≥ 1.25D者占29.68%，<0.25D者占3.82%。疑似原发性闭角型青光眼（PACS）、原发性闭角型青光眼（PAC）和原发性闭角型青光眼（PACG）的角膜散光分别为1.08±0.77 D、0.98±0.62 D和0.89±0.69 D。总体上，50.60%的眼睛被分类为逆规散光（ATR），28.69%的眼睛符合规则，20.71%的眼睛是斜散光。ATR散光随年龄增长而增加（P<0.001）。配对后，PACD组的角膜散光为1.07± 0.77D，高于ARC组的0.98± 0.66D（P=0.018），但无临床差异。结论：该结果为PACD患者角膜散光提供了正常值。角膜散光主要分布在0.25 ~ 1.25D之间。这一发现与已发表的年龄相关性白内障受试者的结果基本一致。
Purpose: The purpose of this study was to analyze the demographics and distribution of corneal astigmatism before lens extraction in patients with primary angle closure disease (PACD). Methods: Preoperative partial coherence interferometry was performed in patients with PACD. The demographic and biometric data, including corneal astigmatism and keratometry (K), were recorded. Results: The study comprised 808 cases (1001 eyes) with a mean age of 67.66±9.07 years, and the mean axial length was 22.55±0.89 mm. The mean corneal astigmatism was 1.08±0.78 diopter (D). Corneal astigmatism was between 0.25 D and 1.25 D in 66.50% of the eyes, 1.25 D or higher in 29.68% of the eyes and <0.25 D in 3.82% of the eyes. The corneal astigmatism of primary angle closure suspect (PACS), primary angle closure (PAC) and primary angle closure glaucoma (PACG) were 1.08±0.77 D, 0.98±0.62 D, and 0.89±0.69 D, respectively. In total, 50.60% of the eyes were classified as astigmatism against the rule (ATR), 28.69% of the eyes were with the rule, and 20.71% of the eyes were oblique. ATR astigmatism increased significantly with age (P<0.001). After matching, corneal astigmatism of PACD was 1.07±0.77 D, although it was statistically significantly higher than that of ARC (0.98±0.66 D, P=0.018), the 2 demonstrated no clinical difference. Conclusions: The results provide normative data of corneal astigmatism for PACD patients. Corneal astigmatism was mainly distributed between 0.25 D and 1.25 D. The findings largely concur with published results in age-related cataract subjects.
