A number of recent studies have demonstrated the success of Nd:YAG and diode laser transscleral cyclophotocoagulation in the treatment of advanced glaucoma. Wavelength selection, however, has seldom been based on a clear understanding of the optical properties of tissues involved. The optical properties of conjunctiva, sclera, and the ciliary body adjacent to the limbus were investigated to find an optimal wavelength range for transscleral cyclophotocoagulation. The absorption and scattering coefficients of these layers were determined in the 300-1200-nm wavelength range by the use of a one-dimensional inverse adding-doubling method. The measured optical properties of conjunctiva, sclera, and the ciliary body provide a basis for a comparative analysis of the laser wavelengths used clinically for transscleral cyclophotocoagulation.
钇铝石榴石（Nd:YAG）和二极管激光经巩膜睫状体光凝术在治疗晚期青光眼方面的成功。然而，波长的选择很少基于对所涉及组织光学特性的清晰理解。为了找到经巩膜睫状体光凝术的最佳波长范围，对结膜、巩膜以及角膜缘附近的睫状体的光学特性进行了研究。通过使用一维逆倍增法在300 - 1200纳米波长范围内测定了这些层的吸收系数和散射系数。所测得的结膜、巩膜和睫状体的光学特性为临床上用于经巩膜睫状体光凝术的激光波长的比较分析提供了基础。
