Red blood clots in the eyes are often the manifestation of intraocular hemorrhage, which can be seen in the subconjunctival capillary dilation or capillary rupture resulting in congestion, trauma and other causes of anterior chamber blood accumulation or fundus vascular lesions causing fundus hemorrhage, which can be relieved by cold or hot compresses. 1. The hemorrhage can be dotted or patchy in distribution, bright red in the early stage, mostly becoming dark red after a week, considered to be related to allergy or external stimulation. In the early stage, local cold compresses can be applied to constrict the blood vessels to reduce bleeding, and hot compresses can be applied after 48 hours to promote blood circulation and absorption. Patients with large blood clots can use blood-stasis activating drugs under the guidance of doctors, such as compound salvia tablets, compound thromboxane capsules, etc.; 2, retinal hemorrhage: in addition to blood clots, patients can feel black spots, flying mosquitoes, spider webs in front of their eyes. 3, anterior chamber bleeding: mostly related to violence, trauma, or hemorrhagic glaucoma and other factors. In addition to blood clots, the patient may also experience decreased vision or increased intraocular pressure. Patients need to actively search for bleeding factors, promptly apply cold compresses to constrict blood vessels and seek medical attention. If bleeding still occurs, hemostatic drugs and IOP-lowering drugs, such as trichothecene and β-blockers, can be used under the guidance of a doctor, and surgery is feasible when conservative treatment is ineffective. In mild cases, only mosquito symptoms may appear, while in severe cases, vitreous blurring and vision loss may occur. A small amount of bleeding can be absorbed on its own and does not require special treatment. If the bleeding is large and the clot cannot be absorbed on its own, the patient should go to the hospital for vitrectomy in time; 5. Fundus bleeding: Systemic vascular and hematological lesions may cause fundus bleeding, and local lesions such as fundus retinal vasculitis and retinal hemangioma may also lead to fundus bleeding and symptoms of blood clots. Patients need to seek medical attention in a timely manner, combined with examination and treatment of the primary disease, and follow medical advice to use blood activating and blood stasis type drugs to promote blood circulation, or surgical methods to remove the clot for treatment.
