PURPOSE
To evaluate the effect of laser peripheral iridotomy (LPI) on biometric parameters including central anterior chamber depth (CACD) in primary angle closure suspect eyes.
METHODS
Eyes classified as primary angle closure suspect were enrolled in this interventional case series. Biometry with Lenstar (Haag-Streit AG, Koeniz, Switzerland) was performed before LPI and 6 weeks afterward. Central anterior chamber depth, lens thickness, axial length, and central corneal thickness were measured before and after the intervention.
RESULTS
Forty eyes of 40 patients with mean age of 56.5 ± 5.5 years were studied. Mean central anterior chamber depth was 2.07 ± 0.21 mm before and 2.08 ± 0.19 mm after LPI (p = 0.8). There was no significant change in lens thickness, axial length, and central corneal thickness after LPI.
CONCLUSIONS
Central anterior chamber depth "measured by Lenstar" does not change after LPI in primary angle closure suspect eyes.
目的
评估激光周边虹膜切开术（LPI）对原发性闭角型青光眼可疑眼生物测量参数的影响，包括中央前房深度（CACD）。
方法
将分类为原发性闭角型青光眼可疑的眼睛纳入此干预性病例系列。在LPI术前和术后6周使用Lenstar（瑞士科尼茨哈格-施特赖特公司）进行生物测量。在干预前后测量中央前房深度、晶状体厚度、眼轴长度和中央角膜厚度。
结果
研究了40例患者的40只眼睛，平均年龄为56.5±5.5岁。LPI术前中央前房深度平均为2.07±0.21mm，术后为2.08±0.19mm（p = 0.8）。LPI术后晶状体厚度、眼轴长度和中央角膜厚度无显著变化。
结论
在原发性闭角型青光眼可疑眼中，LPI术后用“Lenstar测量的”中央前房深度无变化。
