Patient's question:
What harm can breathing opportunities do to the baby's eyes? Previous rescue situations and effects: What harm can breathing opportunities do to the baby's eyes, what kind of assistance is needed: What harm can breathing opportunities do to the baby's eyes, my baby is already 3 months old and...Doctor's answer:
The baby was born full-term, and the retina has already developed fully. A ventilator will never cause any interference to the baby's eyes. If your baby was born prematurely, then because her retina has not yet fully developed, the oxygen concentration used by the ventilator is relatively high. A fully developed retina is highly sensitive to oxygen, and high concentrations of oxygen can cause retinal blood vessels to constrict or block, leading to edema. Edema can then disrupt the development of angiogenic factors, impairing the growth of new blood vessels in the retina. These new blood vessels are often accompanied by fibrosis, where fibrotic tissue grows backward toward the back of the eye, forming a fibrous membrane behind the lens. As the fibrous membrane tightens, it pulls the peripheral retina inward, causing retinal detachment, which can ultimately lead to blindness. Currently, scholars both domestically and internationally recommend that premature infants with gestational ages below or equal to 32 weeks and birth weights below or equal to 1500 grams undergo fundus examinations four weeks after birth. Based on the initial examination results, if there are no issues, follow-up examinations can be conducted every week until four to six months after birth. We suggest that you wait for another one or two months for the examination. We wish your baby good health!
