玻璃体是一种透明的凝胶状组织,对于维持眼球的正常生理功能起着重要作用。当无论任何原因造成玻璃体出血时,一方面因血液遮挡光线进入眼内引起视力降低;另一方面,出血可使玻璃体本身发出变性和纤维组织增殖,以及由此而续发牵引性视网膜脱离,导致永久性视功能障碍;同时,出血还会给眼底病变的检查带来困难。因此,凡遇到玻璃体出血病人应尽可能设法查明原因,给予妥善地处理。
The vitreous is a clear, gel-like tissue that plays an important role in maintaining the normal physiological function of the eyeball. When the vitreous hemorrhage is caused by any reason, on the one hand, the blood will block the light and cause the vision loss; on the other hand, the hemorrhage can make the vitreous itself degenerate and proliferate the fibrous tissue, and the traction retinal detachment will be caused by this Permanent visual impairment; the same time, the bleeding will give retinoscopy lesions difficult. Therefore, whenever patients encounter vitreous hemorrhage should try to identify the cause, give proper treatment.
