目的：探讨计算机图像分析系统在活体眼前节定量检查中的应用。方法：用裂隙灯显微镜联合摄像对眼前节进行检查，将所得资料进行计算机图像分析。结果：角膜中央厚度０．４３ｍｍ±０．０５ｍｍ，周边厚度０．５９ｍｍ±０．０４ｍｍ，前曲率半径１０．８９ｍｍ±１．２１ｍｍ，后曲率半径１０．１０ｍｍ±１．１３ｍｍ，前房深度２．４６ｍｍ±０．３８ｍｍ，房角２６．７９°±５．８０°，晶体厚度：５．１７ｍｍ±０．９０ｍｍ，前曲率半径１１．０６ｍｍ±２．１０ｍｍ，后曲率半径６．２７ｍｍ±１．１０ｍｍ。结论：裂隙灯摄像与计算机图像分析系统可用于对活体眼前节的检查与实时定量检测分析，是晶状体混浊程度定量检查不可缺少的客观手段之一。
Objective: To discuss the application of computerized image analysis system in quantitative examination of anterior segment of living body. Methods: Slit lamp microscopy combined with imaging of the anterior segment to check the information obtained by computer image analysis. Results: The central corneal thickness was 0.43mm ± 0.05mm, the peripheral thickness was 0.59mm ± 0.04mm, the former curvature radius was 10.89mm ± 1.21mm, the latter was 10.10mm ± 1.13mm and the anterior chamber depth was 2. 46mm ± 0.38mm, angle 26.79 ° ± 5.80 °, crystal thickness: 5.17mm ± 0.90mm, the radius of curvature of the front 11.06mm ± 2.10mm, the radius of curvature of the rear 6.27mm ± 1.10mm . Conclusion: Slit lamp imaging and computer image analysis system can be used for the inspection and real-time quantitative detection and analysis of the anterior segment of the living body. It is one of the objective measures which is indispensable for quantitative examination of the degree of lens opacity.
