本文介绍一种新而简单的手术—冷冻虹膜睫状体切除术,此手术适用于波及到睫状体的小而孤立的虹膜肿瘤。作者报告一例30岁妇女,双眼矫正视力为1.0。右眼虹膜可见一灰红色肿物,其大小为3×2×2mm,范围由鼻下4:30至6点钟。病变处可见几条大血管走行其上,并有细尘状色素围绕其基底。瞳孔于5点钟处呈尖形。病变扩展到角膜缘外。房角镜检查见病变区与睫状体间的虹膜组织正常。眼压正常,其余眼部在正常范围内。半年后肿瘤纵横增长至Schwalbe线。一年后肿瘤边缘已接近到睫状体。鉴于肿瘤的高度发展,使病变后面的房角难以看到,因而作冷冻虹膜睫状体切除术,其手术方法如下:以穹窿部为基底作球结膜环状切开,然后在下方由3:00—9:00点钟作180°的角巩膜缘切口。在5点钟处角膜周边部缝一带结缝线,提起角膜,夹持病变一侧 This article describes a new and simple procedure, the Frozen Icy Excision, which is suitable for small, isolated iris tumors affecting the ciliary body. The author reported a 30 year old woman with a corrected visual acuity of 1.0. Right eye iris visible a gray-red tumor, the size of 3 × 2 × 2mm, ranging from 4:30 to 6:00 under the nose. Lesions visible at several large blood vessels running on it, and fine dust-like pigment around its base. The pupil is pointed at 5 o’clock. Lesions extend beyond the limbus. Gonioscopy showed normal iris tissue between the lesion and the ciliary body. IOP normal, the rest of the eye in the normal range. Six months after the tumor grew to the Schwalbe line. One year later the tumor margin is close to the ciliary body. In view of the high degree of tumor development, so that the corner of the back of the lesion is difficult to see, so for frozen iridocycytectomy, the surgical methods are as follows: the fornix for the basal endocervical ring incision, and then from the bottom by the 3: 00-9: 00 o’clock for 180 ° angle scleral incision. At 5 o’clock at the corneal suture around the Department of knot suture, lift the cornea, gripping the lesion side
