The vitreous is a clear gel which is located in the middle section of the eye. It is transparent so allows light coming into the eye to pass through onto the retinal surface.
Sometimes the blood vessels in the eye can break and bleed resulting in blood flooding into the vitreous. If this happens the vitreous becomes filled with blood and is no longer clear. This can prevent the light passing through it onto the retina and causes a loss of vision in the eye.
This condition can appear quickly and painlessly, and you may experience symptoms ranging from spots or floaters in your vision to a sudden blurring of your vision, or in severe cases sudden total loss of vision can result.
Sometimes the haemorrhage will clear up without intervention over several months but if it does not treatment may be required.
It is important that you pay attention to the symptoms and that you undergo an examination so that any necessary treatment can be given.
