Yes, keratoconus can occur in children, although it is more common in adolescents and young adults.
Keratoconus typically has its onset at puberty and progresses until the third to fourth decade of life, when it usually stabilizes. However, some cases of keratoconus have been reported in children as young as 4 years old. In pediatric patients, keratoconus is often more advanced at diagnosis and its progression may be more frequent and more rapid with a sevenfold higher risk of requiring corneal grafting.
