Endoscopic diode laser cyclophotocoagulation with a limbal approach was reviewed retrospectively. The delivery system and procedure used as well as the role of this procedure in the management of glaucoma are discussed.
An 810-nm pulsed continuous-wave diode laser capable of 1.2-W output was used. The maximum treatment area is 7 to 8 clock hours with a single limbal incision. Generally, 800 mW were used for less than 1 second, for a total of 0.8 J per treatment.
Eight eyes of 6 patients were treated. The mean follow-up time for each procedure was 3.2 months (range 1 to 8 months) and for each eye was 5.1 months (range 2 to 8 months). Pre- and postoperative intraocular pressures were determined. Postoperative inflammation was the most common complication.
One reason for the failure of transscleral cyclophotocoagulation, particularly in congenital glaucoma, may be displacement of the ciliary processes. This displacement does not permit the indirect treatment to reach the appropriate area. Because endoscopic laser cyclophotocoagulation allows direct visualization, treatment can be accurately applied to individual ciliary processes.
回顾性分析经角膜缘途径的内镜二极管激光睫状体光凝术。讨论了所使用的输送系统和操作方法以及该手术在青光眼治疗中的作用。
使用一台输出功率为1.2瓦的810纳米脉冲连续波二极管激光。单次角膜缘切口的最大治疗区域为7至8个钟点范围。一般来说，使用800毫瓦，持续时间小于1秒，每次治疗总量为0.8焦耳。
对6例患者的8只眼进行了治疗。每个手术的平均随访时间为3.2个月（范围1至8个月），每只眼的平均随访时间为5.1个月（范围2至8个月）。测定了术前和术后的眼压。术后炎症是最常见的并发症。
经巩膜睫状体光凝术失败的一个原因，尤其是在先天性青光眼中，可能是睫状体移位。这种移位使得间接治疗无法到达合适的区域。由于内镜激光睫状体光凝术可以直接观察，治疗可以准确地应用于单个睫状体。
