Newborns are prone to intraocular hemorrhage: 1. Within one week of birth, the coagulation function of newborns is not yet sound, the plasma prothrombin as well as coagulation factor function is low, and there is a physiological decline in coagulation factors, coupled with the incomplete development of elastic fibers in the blood vessel wall, the fragility of the vessel wall, various bleeding situations are more common. 2, eye: eyelid/orbital/subconjunctival hemorrhage, retinal hemorrhage …… retinal hemorrhage is mostly oozing or punctate hemorrhage, the amount of bleeding is often small while the bleeding is widespread and scattered, and in severe cases, it can cause a large area of bleeding. 3, intracranial pressure and thoracic pressure increase resulting in increased retinal venous pressure, blood return obstruction and neonatal coagulation insufficiency, vascular wall development is related.
