Acute vitreous haemorrhage: A clinical report

In the first hours after a vitreous haemorrhage dense enough to obscure the retina, the blood is usually confined to the posthyaloid space in an aqueousphase. Binocular occlusion and elevation provides sufficient immobilization of the eyes in nine out of i o 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.
