To describe a technique of vitreous base visualisation through trans-scleral illumination using a standard 25-gauge light probe.
All vitrectomies are performed using 25-gauge+ instruments and valved trocars. A non-contact viewing system is used to visualise the retina. After core vitrectomy and the necessary additional procedures, triamcinolone acetonide (Kenacort) is injected in the vitreous cavity. Then, the standard 25-gauge light pipe is covered with a sleeve obtained from a 20-gauge venflon cannula. The light brightness is increased to 100%, and the light probe used to indent the sclera and trans-illuminate the vitreous base. The vitreous cutter is activated between the crystals of triamcinolone acetonide and the retinal surface. Complete vitreous base shaving is carried out for 360°.
Iatrogenic peripheral retinal tears, as a result of vitreous shaving, occurred in 4.1% of cases with this technique.
This method represents a valid and low-cost option to achieve accurate vitreous base shaving.
描述一种使用标准 25 号光探头经巩膜光照明进行玻璃体基底部可视化的技术。
所有玻璃体切除术均采用 25 号+器械和带阀套管针进行。使用非接触式观察系统来观察视网膜。在进行核心玻璃体切除和必要的附加手术后，将曲安奈德（肯纳科特）注射到玻璃体腔中。然后，用从 20 号静脉套管针获得的套管覆盖标准 25 号光管。将光亮度增加到 100%，并使用光探头压陷巩膜和经巩膜透照玻璃体基底部。在曲安奈德晶体和视网膜表面之间激活玻璃体切割器。进行 360°的完整玻璃体基底部刮除。
在使用该技术的病例中，玻璃体刮除术导致医源性周边视网膜裂孔的发生率为 4.1%。
这种方法是一种有效且低成本的选择，可以实现准确的玻璃体基底部刮除。
