Foreign bodies may drop during removal from the posterior segment and result in foveal damage. Due to high specific gravity and viscosity, ophthalmic viscosurgical devices (OVDs) can dampen and redirect the force of the dropping foreign body and therefore protect the fovea. Herein we describe our technique of foveal protection with OVDs and briefly demonstrate the results in five eyes with large posterior segment foreign bodies.
异物在从后段取出过程中可能掉落并导致黄斑损伤。由于眼用粘性手术器械（OVDs）具有较高的比重和粘度，它们可以缓冲并改变掉落异物的力量，从而保护黄斑。在此，我们描述了使用OVDs保护黄斑的技术，并简要展示了5例伴有后段大异物的患眼的治疗结果。
