To study the internal diameter of the anterior chamber (AC), which remains a relatively subjective procedure dominated by the white-to-white technique, evaluated with a compass or using anterior segment photographs. In vivo dimensions of the AC were studied with an optical coherence tomographer (AC OCT) prototype.
Clinique Monticelli, Marseilles, France.
The dimensions in 107 normal eyes that had never had surgery were studied with the IOLMaster and AC OCT.
The mean anterior chamber depth was 3.53 mm +/- 0.35 (SD) with the IOLMaster (Carl Zeiss, Medictec) and 3.64 +/- 0.33 mm with the AC OCT (Carl Zeiss, Medictec). The mean horizontal diameter of the AC was 12.12 +/- 0.44 mm with the IOLMaster and 12.20 +/- 0.44 mm with the AC OCT. With the AC OCT, the anterior chamber's horizontal and vertical diameter could be evaluated; in 74% of the observed eyes, the vertical diameter was larger by at least 100 mum than the horizontal diameter.
The AC OCT has better reproducibility than the IOLMaster for evaluating the depth or internal diameter of the anterior chamber. This study showed that in 74% of cases, the AC was an oval with a larger vertical axis, which provides evidence of the value of the OCT preoperative examinations for phakic intraocular lens implantation.
研究前房内径，目前该测量方法仍相对主观，主要采用白对白技术，通过使用圆规或前段照片进行评估。利用光学相干断层扫描仪（AC OCT）原型对前房的活体尺寸进行研究。

使用IOLMaster和AC OCT对107只从未接受过手术的正常眼睛的尺寸进行研究。
使用IOLMaster（卡尔蔡司医疗技术公司）测量的平均前房深度为3.53 mm±0.35（标准差），使用AC OCT（卡尔蔡司医疗技术公司）测量的平均前房深度为3.64±0.33 mm。使用IOLMaster测量的前房平均水平直径为12.12±0.44 mm，使用AC OCT测量的为12.20±0.44 mm。使用AC OCT可以评估前房的水平和垂直直径；在74%的观察眼中，垂直直径比水平直径至少大100μm。
在评估前房深度或内径方面，AC OCT比IOLMaster具有更好的可重复性。本研究表明，在74%的病例中，前房为垂直轴较大的椭圆形，这为OCT术前检查在有晶状体眼人工晶状体植入术中的价值提供了证据。
