Introduction
Under normal circumstances, coagulation dysfunction may cause retinal hemorrhage in newborns; if necessary, it is recommended to consult a physician. Coagulation dysfunction means that the prothrombin and coagulation factor functions in the newborn's plasma are reduced, and physiological coagulation factors are also decreased. In such cases, the elastic fibers of the newborn's blood vessel walls are underdeveloped, making the vessel walls very fragile.
In general, coagulation dysfunction may cause retinal hemorrhage in newborns. If necessary, it is recommended to consult a physician for advice. Detailed analysis is as follows:
Coagulation dysfunction means that the newborn's plasma has reduced levels of prothrombin and clotting factors, along with decreased physiological clotting factors. In such cases, the elastic fibers in the blood vessel walls of newborns are underdeveloped, making the vessel walls very fragile. When the vessel walls experience pressure or stimulation, they are prone to rupture and bleeding. Therefore, newborns with coagulation dysfunction may develop retinal hemorrhage even after minor damage to the retinal blood vessels.
Newborns generally have unstable emotions. Frequent crying can increase intracranial pressure and abdominal pressure, which in turn elevates retinal venous pressure, causing impaired blood return. In cases of coagulation dysfunction, this impaired venous return more easily leads to rupture and bleeding of the retinal vessels. Additionally, the ocular tissues of newborns are inherently fragile, making retinal hemorrhage more likely even after minor external injuries.
Parents should take care to avoid any external injury to the newborn's eyes, maintain ocular cleanliness, and prevent infections.
