眼球内异物伤是严重影响视力甚至是毁坏眼球的主要原因之一。目前,有关玻璃体内异物与力学关系方面的研究尚未见系统报道。本文就这个问题作一初步探讨。材料与方法(一)选用健康猪的新鲜眼球8个,分别将8个眼球赤道部之眼球壁各切开一个5×9毫米的“小窗”,并将此处的玻璃体界膜破坏。然后使“小窗”向上平放在桌面上,使”小窗”处玻璃体液面深达24毫米 Intraocular foreign body injury is one of the main reasons that seriously affect the eyesight and even destroy the eyeball. At present, there is no systematic report about the relationship between the intravitreal foreign body and the mechanics. This article makes a preliminary discussion on this issue. Materials and methods (a) Choose fresh pig’s eye 8, respectively, the eyeball wall of the eight eye equatorial Department cut a 5 × 9 mm “small window”, and here the destruction of the vitreous body membrane. Then “small window” up flat on the desktop, so that “small window” vitreous liquid at a depth of 24 mm
