The fundus, including: the vitreous and the retina. Bleeding in the fundus, then, includes vitreous hemorrhage and retinal hemorrhage. Depending on the specific site of the hemorrhage, the cause of the hemorrhage, and the amount of the hemorrhage, the symptoms that appear vary. Vitreous hemorrhage: Since the vitreous tissue itself does not have blood vessels and does not bleed on its own, the blood clot in the vitreous comes from the rupture of the retina or choroidal vessels, so strictly speaking, it should be called “vitreous hemorrhage”. The symptoms are: Suddenly, the eyes are blurred, sometimes you can see the dark red blood slowly spread out, like ink drops into water, and finally the whole eye can not see things; even to the extent that you can only see a black shadow moving in front of your eyes, or only the sense of light; when the amount of bleeding is very large and the accumulated blood is thick, there may even be no sense of light. Retinal hemorrhage: The main manifestation is a blocky black area in the visual field with an obvious sense of occlusion. If it occurs in the macular area, the patient’s vision is severely reduced to the point that he cannot see anything. To sum up, the symptoms of fundus hemorrhage are not invariable, as long as the similar symptoms mentioned above appear, you should go to a specialist for professional examination, because the earlier the treatment, the earlier you can save your vision to avoid leaving an irrecoverable disability.
