[Clinical report of a conservative management in treating acute vitreous haemorrhage (author's transl)].

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 aqueous phase. Binocular occlusion and elevation provides sufficient immobilization of the eyes in 9 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. Is this not done, blood will eventually enter the vitreous gel through holes that develop in the posterior hyaloid membrane. Blood in the gel does not settle and requires months to clear.
