Squint generally begins in childhood, which if treated quickly and early can eliminate or at least manage the condition. Thus, when squint is seen in adults, it should be understood that it is the result of progressive untreated squint from childhood. However, this is not always the case. There could be rare instances where the individual may not be having squint in childhood, but may have developed the condition in adulthood due to an eye injury or head trauma. Approximately 4% of adults today suffer from squint, most of them related to accidents, injuries, and medical illnesses.
