Fundus hemorrhage is not a stand-alone disease, but can be caused by a variety of reasons, such as trauma, diabetic retinopathy, etc., and requires timely medical care to improve the fundus photography and other examinations, and then the cause of the symptomatic treatment. Trauma to the fundus causes damage to the retina or choroid, resulting in rupture of blood vessels and hemorrhage, requiring emergency treatment such as vitrectomy, laser photocoagulation, or removal of intraocular foreign bodies. Diabetic retinopathy is caused by systemic endocrine system diseases. When neovascularization occurs in the fundus, the brittle walls of the blood vessels can lead to hemorrhage, which requires long-term glycemic control and laser photocoagulation if necessary. There are many causes of fundus hemorrhage, and if you have a sudden onset of fundus hemorrhage such as a large floating object in front of your eyes, you need to go to the ophthalmology department as soon as possible to complete the fundus photography and other examinations, and after clarifying your condition, you can undergo laser photocoagulation or surgery under the guidance of your doctor.
