A new technique for visualisation of the vitreous base is described. It uses a standard lightpipe for scleral indentation and transillumination. Visualisation of the vitreous using low light levels can be achieved by enhancing the Tyndall effect.
Perfluorocarbon liquid (PFCL) is used to confine the aqueous environment to the anterior vitreous cavity and triamcinolone is added to increase light scatter. The technique clearly differentiates vitreous from PFCL and infusion fluid, and facilitates trimming of the vitreous base, draining of subretinal fluid and air/fluid exchange.
描述了一种用于可视化玻璃体基底部的新技术。它使用标准光导纤维进行巩膜压陷和透照。通过增强廷德尔效应，可以在低光照水平下实现玻璃体的可视化。
使用全氟碳液（PFCL）将水性环境限制在前部玻璃体腔，并添加曲安奈德以增加光散射。该技术能清晰地区分玻璃体与PFCL及灌注液，便于修剪玻璃体基底部、引流视网膜下液以及进行气/液交换。
