Fundus hemorrhage is the abnormal rupture of the retinal and choroidal vessels in the fundus of the eye resulting in hemorrhage. There are many causes, some are caused by local factors in the eye, some are secondary to systemic diseases, and some are unexplained fundus hemorrhages in clinical practice. The common causes of fundus hemorrhage are retinal vascular diseases, inflammatory diseases, optic nerve diseases, and choroidal lesions. Common systemic diseases that cause fundus hemorrhage include hypertension, diabetes mellitus, and leukemia. Fundus hemorrhage can occur at all ages, and it can also occur in newborns, especially in newborns born in a normal or premature birth. In a normal birth, the baby is delivered through the mother’s birth canal, and the squeezing force of the birth canal can cause fundus hemorrhage in newborns, and premature babies, especially those with a history of oxygen absorption, are prone to retinopathy of prematurity, which causes fundus hemorrhage. Depending on the site of occurrence, there are superficial hemorrhage and deep hemorrhage. Superficial hemorrhage refers to hemorrhage located on the surface of the retina, while deep hemorrhage refers to hemorrhage located under the retina. Depending on the form of the hemorrhage, there are point-like hemorrhages, sheet-like hemorrhages, and flame-like hemorrhages. In conclusion, fundus hemorrhage is the outflow and accumulation of blood due to rupture of blood vessels or abnormal neovascularization caused by various causes.
