近年来实验研究证明,超声波作用于小梁组织,可增强房水的滤过,小梁超声术已成为一个新的抗青光眼手术。本文介绍了其远期手术效果。手术方法:球后及球结膜下麻醉后,于角膜缘上方10mm处切开球结膜,作三角形巩膜瓣,厚度为巩膜的1/2,基底向角膜缘。切除深层巩膜条,大小约5×1mm,连同Schlemm管一起切除。用超声波探头(直径不超过1mm)接触伤口。作用于小梁时间为8～10秒,振幅为6～8欧姆,频率为44赫兹。作用于巩膜突时间为20
In recent years, experimental studies have shown that ultrasound on the trabecular tissue, can enhance the filtration of aqueous humor, trabecular ultrasound has become a new anti-glaucoma surgery. This article describes its long-term surgical results. Surgical methods: After the ball and subconjunctival anesthesia, 10mm above the corneal margin at the top of the cut ball conjunctiva, for the triangular scleral flap, the thickness of the sclera 1/2, basal to the limbus. Excision of deep scleral strips, the size of about 5 × 1mm, together with the Schlemm tube resection. Contact the wound with an ultrasonic probe (no more than 1 mm in diameter). Effect on the trabecular time is 8 to 10 seconds, the amplitude of 6 to 8 ohms, the frequency of 44 hertz. Role in the scleral protrusion time is 20
