Astigmatism in infants may be caused by congenital uneven development of corneal curvature, corneal trauma and eye diseases.
1. Uneven development of congenital corneal curvature: it is usually due to the poor development of corneal morphology during embryonic development, resulting in uneven corneal morphology, with some areas being high and some areas being low, forming an uneven morphology, which may cause astigmatism.
2. Corneal trauma: If an infant accidentally suffers corneal trauma, it is likely to lead to a change in the curvature of the cornea, resulting in astigmatism. It may also be due to scarring in the deeper stromal layer of the wound after healing, which may cause astigmatism to worsen.
3. Eye diseases: If an infant suffers from eye diseases such as keratitis and corneal ulcers, it may cause corneal astigmatism, which can lead to the formation of astigmatic eyes in infants.
If an infant has astigmatism, which causes abnormal vision and other discomforts, it is recommended to consult a doctor for examination to clarify the cause, and then appropriate interventions will be given if necessary.
