Amblyopia (Lazy Eye) Overview
Amblyopia, commonly referred to as lazy eye, is a condition in which vision does not develop normally in one or both eyes during early childhood. It arises when the brain does not receive clear or balanced visual input from the eyes during a critical period of visual development.
In normal visual development, both eyes work together to send clear and coordinated images to the brain. When this process is disrupted, the brain may begin to rely more on one eye while reducing input from the other. Over time, this can lead to reduced visual function in the affected eye, even if the eye itself appears structurally normal.
Amblyopia is primarily a condition of the visual system rather than a problem with the eye alone. It reflects how visual signals are processed and integrated by the brain. Because it develops during early childhood, it is closely linked to the timing of visual maturation.
The impact of amblyopia can vary, but it often affects visual clarity and the ability to use both eyes together effectively. Early identification is important in supporting normal visual development and reducing long-term visual limitations.
When to seek assesment
Eye assessment is recommended during early childhood to monitor normal visual development, even if no concerns are apparent. You should seek evaluation if a child shows signs such as favouring one eye, difficulty focusing, poor depth perception, or if the eyes do not appear aligned.
If you are concerned about your child’s vision or would like to assess their visual development, schedule a consultation with Dr Cronjé Ophthalmologist & Eye Surgeon | FC Ophth (SA) | MBChB (Pret) | Dip Ophth (SA) for expert evaluation and personalised care.
