玻璃体积血是最常见的玻璃体病变,是外伤、眼病或全身出血性疾病导致视力障碍的一种常见病症。可造成屈光间质混浊,不仅造成视力障碍,妨碍眼底检查,还对眼其他组织产生严重破坏作用,引起其它并发症,如玻璃体液化、机化、后脱离,继发血细胞性青光眼等。由于玻璃体内无血管,玻璃体内的积血通常来自视网膜或脉络膜的破损的血管或新生血管。所以其代谢极其缓慢,造成积血后吸收十分困难,致盲率甚高。
Vitreous hemorrhage is the most common vitreous disease and is a common condition of visual impairment caused by trauma, ocular or systemic hemorrhagic disease. Can cause refractive interstitial opacity, not only cause visual impairment, obstruct the fundus examination, but also have serious damage to other tissues of the eye, causing other complications, such as vitreous liquefaction, mechanization, posterior detachment, secondary blood cell glaucoma. Due to the absence of blood vessels in the vitreous, vitreous hemorrhage usually comes from damaged blood vessels or neovascularization of the retina or choroid. So its metabolism is extremely slow, resulting in very difficult absorption after hemoperfusion, high blindness rate.
