Infants with red eyes with red blood are not normal and can often be caused by a variety of reasons. If the infant is found to have red bloodshot eyes at birth, eye injury caused by trauma during delivery should be ruled out, which is usually accompanied by a patchy conjunctival hemorrhage; if the eyes are found to be red and have increased discharge, it may be conjunctivitis caused by infection in the birth canal; if the discharge is found to be increasing, conjunctivitis caused by gonococcal infection should be alerted; if the infant has obvious eczema-like changes on the skin after birth and has obvious red bloodshot eyes, it may be related to allergies; if the infant has red bloodshot eyes after birth, it may be related to allergies. If the infant has obvious eczema-like changes on the skin and obvious red bloodshot eyes after birth, it may be related to allergies; if after birth, the infant often has tearing in one or both eyes, increased red bloodshot, and increased eye discharge, it may be caused by congenital tear duct obstruction, secondary to infection; in addition, the infant’s eyelids have impingement, and similar symptoms may occur. Therefore, when infants have red eyes with red blood, they can be observed temporarily, and if the symptoms tend to worsen, they should go to the hospital’s ophthalmology department without delay to avoid adverse consequences.
