Silicone oil (SO) tamponade is frequently used in complex vitreoretinal surgeries, and SO migration into the anterior chamber can lead to complications, such as glaucoma and corneal decompensation. A new technique is described for the efficient removal of emulsified SO droplets, which can adhere strongly to the anterior surface of the iris.
The tip of an ophthalmic absorption sponge was cut to an approximately 1 mm × 1 mm size. Using forceps, the sponge was inserted through a 25-gauge trocar and then through a corneal paracentesis to gently scrape the surface of the iris to dislodge the adherent SO droplets, which were subsequently aspirated.
This technique efficiently and effectively dislodged and mobilized most emulsified SO droplets, thereby allowing removal through aspiration using a vitrector. Two months after surgery, the retina remained attached, the intraocular pressure decreased from 18 mm Hg to 15 mm Hg, and there were no visible SO droplets in the anterior chamber.
The sweeping technique is a safe and efficient method to dislodge, mobilize, and aspirate emulsified SO droplets that are adherent to the anterior surface of the iris, thereby decreasing the risk of future SO-related complications.
硅油（SO）填塞常用于复杂的玻璃体视网膜手术，而硅油向前房迁移可导致并发症，如青光眼和角膜失代偿。本文描述了一种有效去除乳化硅油滴的新技术，这些硅油滴可强烈粘附于虹膜前表面。
将眼科吸收海绵的尖端剪成约1mm×1mm大小。用镊子将海绵通过25G套管针插入，然后通过角膜穿刺术轻轻刮擦虹膜表面，以去除粘附的硅油滴，随后将其吸出。
该技术有效且高效地去除了大多数乳化硅油滴，从而可通过玻璃体切割器吸出。术后两个月，视网膜保持附着，眼压从18mmHg降至15mmHg，前房内未见明显硅油滴。
清扫技术是一种安全有效的方法，可去除、移动并吸出粘附于虹膜前表面的乳化硅油滴，从而降低未来与硅油相关并发症的风险。
