What is the treatment for vitreous hemorrhage?
Small vitreous hemorrhages may be treatable with a laser treatment that repairs the bleeding vessels and tears in the retina, if applicable. Once the source of bleeding has been repaired, it can take several weeks for the blood that has accumulated in the eye to clear.
How long does it take for vitreous hemorrhage to clear?
Normally, no treatment is needed for a vitreous hemorrhage. The blood should clear by itself and your vision will be restored. Unfortunately, this may take up to several months. Your eye doctor will follow up with you and monitor this condition until it goes away.
Is vitreous hemorrhage serious?
Vitreous haemorrhage resulting from posterior vitreous detachment usually has a good prognosis, with restoration of vision, particularly if the eye is otherwise normal. Where severe diabetic eye disease or macular degeneration has resulted in abnormal blood vessels, the outlook for the vision is much less good.
What does Cloquet’s canal contain?
Hyaloid canal (Cloquet’s canal and Stilling’s canal) is a small transparent canal running through the vitreous body from the optic nerve disc to the lens. In the fetus, the hyaloid canal contains a prolongation of the central artery of the retina, the hyaloid artery, which supplies blood to the developing lens.
Where does a vitreous hemorrhage occur in the Cloquet Canal?
In the Cloquet canal, vitreous hemorrhage tends to delineate its inferior border and that within the retrohyaloid space caused by vitreous detachment may accumulate as a meniscus at the inferior vitreoretinal boundary, boat-shaped hemorrhage.
Is there extravasated blood in the vitreous cavity?
Any blood in the vitreous cavity is known as vitreous hemorrhage (VH). By definition, it is the presence of extravasated blood within a space lined by posterior lens capsule anteriorly, internal limiting membrane (ILM) posteriorly, and non-pigmented epithelium of ciliary body laterally. [1] Anatomically, it can be present in the following spaces:
How is a vitreous hemorrhage similar to a retrohyaloid?
Similarly, vitreous hemorrhage within the space between the internal limiting and the nerve fiber layer may resemble that within the retrohyaloid space, except that the blood does not shift with change in the head position as may be the case with subhyaloid hemorrhage.
Can a vitreous hemorrhage break through the subretinal space?
Vitreous hemorrhage due to Terson syndrome, anemia, Valsalva retinopathy, shaken baby syndrome, and retinal macroaneurysm rarely breaks through the internal limiting membrane or into the subretinal space.
