方法选择接受双眼CustomVueTM个体化角膜屈光手术的近视患者86例172眼，术前应用Wavesan像差测量仪在坐位时进行虹膜识别，术中应用VISX Star S4 IR进行卧位时虹膜定位，记录眼球旋转及瞳孔中心移位。

Methods 1038 eyes of 606 consecutive myopic patiences who had bilateral Custom Vue LASIK between March 2006 and August 2006 were involved in the study. Wavefront measurement and iris registration were performed in the upright position with Wavescan aberrometer, then more over iris registrations were performed in the supine positon during the operation with VISX Star S4 IR.

Objective To evaluate intraocular dimensions of the anterior segment and examine decentration, tilt and anterior chamber depth of myopic phakic eyes after implantation of iris-fixated lenses. Methods Thirty-three myopic eyes that received a iris-fixated phakic intraocular lens were assessed.

目的 应用Pentacam术后追踪测量虹膜夹型有晶状体眼人工晶状体中央和周边部与角膜内皮和自然晶体之间的距离，倾斜度、偏心值以及前房深度的变化，评价其在前房的位置。

This paper introduces an approach for locating an iris using integrodifferential operators based on the circular geometry of the iris.

人体各生物组织可用作身份识别的有指纹、脸型、DNA虹膜等，而以虹膜识别最简便、最准确。

Result: A 77-year-old female presented at our hospital for blurred vision in her right eye. The intraocular pressure was 46 mmHg and slit lamp examination showed a protruding mass with papillomatous appearance near pupil margin. On chest X-ray examination, only prominent left hilum was noted. Iris tumor excisional biopsy was performed. Pathology investigation of the surgical specimen revealed carcinoma and immunohistochemical study demonstrated thyroid transcription factor-1 (TTF-1) positive. Chest-computed tomography showed left upper lung tumor and primary pulmonary adenocarcinoma was confirmed after CT-guided biopsy. She was placed under treatment with Genfitinib. Recurrent iris tumor mass was noted during follow-up, and chest CT revealed shrinkage of adenocarcinoma.

结果：一位七十七岁女性因右眼视力模糊至本院就诊，当时眼压为46毫米汞柱，细隙灯检查发现虹膜靠近瞳孔边缘有一乳突状肿块，胸部X光摄影仅见左肺门稍明显并未发现明显病灶，患者接受虹膜肿瘤切除手术，病理报告显示为恶性肿瘤，且免疫组织染色为thyroid transcription factor-l阳性，进一步的胸部电脑断层显示左上肺肿瘤，经电脑断层指引之切片检查证实为原发性肺腺癌，她接受Genfitinib药物治疗，后续追踪发现虹膜肿瘤复发，胸部电脑断层扫描显示肿瘤体积缩小。

The albinism is characterized by hypopigmentation of the skin and hair and the ocular findings of reduced iris pigment with iris transillumination, reduced retinal pigment, foveal hypoplasia with significant reduction in visual acuity (usually in the range of 20/50 to 20/400), nystagmus, and increased crossing of the optic nerve fibers.
