In the first hours after a vitreous haemorrhage dense enough to obscure the reina, the blood is usually confined to the posthyaloid space in an aqueous phase. Binocular occlusion and elevation provides sufficient immobilization of the eyes in nine out of 10 patients for the blood cells to settle to the bottom of the space and make the retina available for examination and repair. Blood enters the vitreous gel through holes that develop in the posterior hyaloid membrane. Blood in the gel does not settle and requires months to clear.
在玻璃体积血严重到足以遮挡视网膜后的最初几个小时内,血液通常以水相形式局限于玻璃体后间隙。对于十分之九的患者,双眼遮盖并抬高头部可使眼球充分固定,让血细胞沉降至该间隙底部,从而使视网膜可供检查和修复。血液通过玻璃体后界膜上形成的孔洞进入玻璃体凝胶。凝胶中的血液不会沉降,需要数月才能清除。
