We studied the structure of the normal iris as seen in infrared transillumination photographs of variously pigmented eyes in subjects of different age and sex. To transilluminate the iris infrared light was passes via a fiber-glass optic through the lateral wall of the globe and photographs were taken with a Zeiss stereo slit-lamp camera. The photographs showed that the structural pattern of the iris was similar in both blue and brown eyes of either sex. The iris was rather dense in children, well developed in adults and somewhat atrophic in the elderly. On the posterior surface of the iris the radial contraction folds and the structural folds of Schwalbe and circular contraction folds were seen; they were delicate in children and more pronounced in adults and the elderly. The pupillary part of the iris ballooned forward in young people whereas in the elderly the whole iris had this configuration.
我们研究了不同年龄和性别的受试者中，各种色素沉着眼睛的红外透照照片所显示的正常虹膜结构。为了对虹膜进行透照，红外光通过玻璃纤维光学器件穿过眼球侧壁，并使用蔡司立体裂隙灯相机拍照。照片显示，无论男女，蓝眼睛和棕眼睛的虹膜结构模式相似。儿童的虹膜相当致密，成年人的虹膜发育良好，老年人的虹膜则有些萎缩。在虹膜后表面可见放射状收缩褶、施瓦贝结构褶和环形收缩褶；它们在儿童中较为纤细，在成年人和老年人中更为明显。年轻人的虹膜瞳孔部分向前膨隆，而在老年人中整个虹膜都呈现这种形态。
