作者以小的睫状体平部内窥镜观察眼内后部异常、摘除眼内异物及后部玻璃体切除。内窥镜有一1.7mm直径的细轴管,装有一圆柱形透镜,以导光纤维连于光源。观察视野为75°。当内窥镜贴近玻璃体视网膜结构时,所看到的面积将变小,而结构被放大约10倍。内窥镜在眼内必须保持平稳,故须装在一同时支持患者头部的位置固定器上,以便扫视视网膜。内窥镜一般由12点钟处睫状体平部巩膜切口进入眼内。如4点钟处锯齿缘有异物,从10点钟位置插入内窥镜为最好。玻璃体切割器的人口如果与内窥镜入口相距小于2个钟点范围就没有足
The author with a small ciliary body endoscopic observation of the posterior intraocular anomalies, removal of intraocular foreign body and posterior vitrectomy. Endoscope has a 1.7mm diameter thin shaft tube, equipped with a cylindrical lens, the light guide fiber connected to the light source. The field of view was 75 °. As the endoscope approaches the vitreoretinal structure, the area seen becomes smaller and the structure is magnified by about 10 times. The endoscope must be stable within the eye and must be mounted on a position holder that also supports the patient’s head for scanning the retina. The endoscope is usually at 12 o’clock ciliary body scleral incision into the eye. If there is a foreign body at the serrated edge at 4 o’clock, it is best to insert the endoscope from the 10 o’clock position. The vitrectomy cutter population has no foot if it is within 2 hours of the endoscope entrance
