低眼压是眼外伤后最严重的并发症之一,长期持续低眼压不仅使视功能降低,且可导致眼球萎缩。低眼压的最典型临床特征为完全无葡萄膜炎或虹膜睫状体炎的基础上而眼压显著降低。视乳头及视网膜后极部水肿,多数形成近视眼。据文献资料外伤后低眼压可有不同原因:玻璃体丧失,睫状体广泛损伤或破坏及睫状体脱离等。外伤后低眼压患者一分钟的房水生成量显著减少,睫状体部血流图系数降低,证明低眼压可能由于外伤后睫状体上皮的破坏性改变,使睫状体分泌功能降低。由于睫状体破裂,虹膜根部离断,Schlemm
Low intraocular pressure is one of the most serious complications after ocular trauma. Long-term continuous intraocular pressure not only reduces visual function, but also leads to atrophy of the eyeball. The most typical clinical characteristic of hypotension is a complete reduction of uveitis or iridocyclitis with a significant reduction in IOP. Optic and retinal posterior pole edema, most of the formation of myopia. According to the literature after traumatic hypotonic pressure may have different reasons: vitreous loss, ciliary body extensive damage or destruction and ciliary body detachment. Traumatic hypotension in patients with a minute of aqueous humor significantly reduced the production of ciliary body blood flow coefficient decreased, suggesting that low intraocular pressure may be due to traumatic ciliary body epithelial destructive changes in ciliary body secretion decreased . Due to the ciliary body rupture, the iris root is severed, Schlemm
