目得：比较25-gauge（25 G）经结膜玻璃体切除术与巩膜隧道和标准25 G经结膜玻璃体切除术之间的眼内液体渗漏率。设计：单中心，回顾性，介入性病例系列。方法：仅使用25 G器械进行经结膜玻璃体切除术与周边玻璃体切除术。标准25 G玻璃体切割术542眼，25 G巩膜隧道玻璃体切割术337眼。巩膜隧道通过以斜角插入套管针创建。结果：与标准25 G玻璃体切除术（9%，50/542只眼）相比，25 G玻璃体切除术（1%，5/337只眼）中使用巩膜隧道时，眼内液体渗漏率显著降低（Fisher精确概率检验：P < .0001）。当在25 G玻璃体切除术中使用（而不是不使用）巩膜隧道时，伤口渗漏率显著降低，无论是不使用空气-气体（P = .0258）还是使用空气交换（P = .0007）。结论：在25 G经结膜玻璃体切除术中使用巩膜隧道可降低伤口渗漏的频率，即使在去除周边玻璃体时也是如此。
PURPOSE: To compare the intraocular fluid leakage rate between 25-gauge (25G) transconjunctival vitrectomy with scleral tunnels and standard 25G transconjunctival vitrectomy.DESIGN: Single-center, retrospective, interventional case series.METHODS: Transconjunctival vitrectornies were conducted by the use of only 25G instruments with peripheral vitrectomy. Standard 25G vitrectomy was conducted in 542 eyes and 25G vitrectomy with scleral tunnels in 337 eyes. The scleral tunnel was created by inserting trocars at an oblique angle.RESULTS: The intraocular fluid leakage rate was significantly lower (Fisher exact probability test: P < .0001) when scleral tunnels were used in 25G vitrectomy (1%, five of 337 eyes) compared with standard 25G vitrectomy (9%, 50 of 542 eyes). The wound leakage rate was significantly lower when using (rather than not) scleral tunnels in 25G vitrectomy, both without air-gas (P = .0258) and with air exchange (P = .0007).CONCLUSION: The use of scleral tunnels in 25G transconjunctival vitrectomy reduces the frequency of wound leakage even when the peripheral vitreous is removed.
