All you need to know about: squint eye
This article explains strabismus, a condition where eyes are misaligned, and its impact on vision development. It highlights global prevalence statistics and the importance of early detection in children.
Why it matters
Understanding common eye conditions is crucial for public health awareness and ensuring timely medical intervention for children and adults.
Squint, or strabismus, is a condition in which the eyes are not aligned and do not look in the same direction at the same time. One eye may turn inwards towards the nose (esotropia), outwards (exotropia), upwards or downwards, while the other eye remains focused on an object. This misalignment may be constant or may occur intermittently, such as when a person is tired.
A recent study estimated that horizontal strabismus affects 1.81% of the global population, or about 138.5 million people. Exotropia affects an estimated 1.14% (87.5 million), compared with 0.67% (60 million) for esotropia. The pattern has also shifted across generations, with exotropia now more common globally. The study found regional differences, but noted that parts of South Asia remain under-represented in research.
