低眼压是眼外伤后最严重的并发症之一。长期持续性低眼压不仅会造成视乳头及视网膜后极部水肿,使视功能降低,且可导致眼球萎缩。多年来,国内、外学者对外伤性青光眼、白内障及球内异物的研究较多,但对外伤后低眼压及其严重的预后却重视不够,本文参阅国内、外文献,仅将与外伤有关的低眼压综述如下: 一、外伤后低眼压的解剖生理学基础众所周知,眼球前段是支配眼压的一个重要解剖学部位,而睫状体和前房角是房水生成和排出的重要器官。目前认为:睫状体上皮既能产生 IOP is one of the most serious complications after ocular trauma. Long-term sustained low intraocular pressure will not only cause edema of the optic nerve and posterior pole of the retina, reducing visual function, and may lead to atrophy of the eyeball. Over the years, domestic and foreign scholars on the traumatic glaucoma, cataracts and intracranial foreign body more research, but post-traumatic hypotensive pressure and its serious prognosis but not enough attention, this article refers to domestic and foreign literature, only with trauma Of the IOP are summarized as follows: First, post-traumatic hypotonic hypothalamic anatomy and physiology Basis It is well known that the anterior segment of the eye is an important intraocular pressure anatomical site, and ciliary body and anterior chamber angle is an important organ of aqueous humor production and discharge . At present that: both ciliary body epithelium
