Abstract：
UNASSIGNED: To report a novel combining a 25-gauge retrobulbar needle with a built-in 30-gauge needle surgical technique for subfoveal perfluorocarbon liquid (PFCL) removal.
UNASSIGNED: Fourteen eyes of 14 patients who underwent subfoveal PFCL removal with a 25-gauge retrobulbar needle combined with a built-in 30-gauge needle were studied. The 30-gauge needle was inserted into the 25-gauge retrobulbar needle. The bent tip of the built-in 30-gauge needle was used to create a 30-gauge retinotomy at the farthest edge of the subfoveal PFCL droplet. Then, a flute cannula was used to aspirate the PFCL through the previously created retinotomy. The best-corrected visual acuity (BCVA) was determined, previous surgical history and post-operative complications were recorded.
UNASSIGNED: Fourteen cases were analyzed. Most eyes (92.85%) showed an improvement in BCVA after surgery. The mean change in the BCVA was -0.7 ± 0.72 logarithm of the minimum angle of resolution (logMAR) units (p = 0.006). Post-operative complications included a self-healing macular hole in one eye and vitreous hemorrhage in one eye. Post-operative optical coherence tomography confirmed removal of the subfoveal PFCL with restoration of the macular fovea.
UNASSIGNED: Combining a 25-gauge retrobulbar needle with a built-in 30-gauge needle to remove subfoveal PFCL is easy to perform and carries little potential risk of subretinal impairment. This method also provides relatively good macular contour with functional improvement.

摘要：
■报告一种新颖的将25号球后针与内置30号针的手术技术相结合，用于中央凹下全氟化碳液体（PFCL）去除。
■研究了14例患者的14只眼，这些患者使用25号球后针结合内置30号针进行了中央凹下PFCL摘除。将30号针插入25号球后针中。内置30号针的弯曲尖端用于在中心凹下PFCL液滴的最远边缘处形成30号视网膜切开术。然后，我们使用长笛套管通过之前创建的视网膜切开术抽吸PFCL.确定了最佳矫正视力（BCVA），记录既往手术史和术后并发症.
■分析14例。大多数眼睛（92.85％）在手术后显示BCVA改善。BCVA的平均变化为最小分辨率角（logMAR）单位的-0.7±0.72对数（p=0.006）。术后并发症包括一只眼睛的自愈性黄斑裂孔和一只眼睛的玻璃体出血。术后光学相干断层扫描证实了黄斑中心凹下PFCL的去除和黄斑中心凹的恢复。
■将25号球后针与内置的30号针结合使用以去除中央凹下PFCL易于执行，并且几乎没有视网膜下损伤的潜在风险。该方法还提供了具有功能改善的相对良好的黄斑轮廓。
