What is Squint?

Ask a Question

Strasbismus, in common par lance also known as Squint or 'Teer' is not uncommon. It affects 2-5% of all children. The condition is brought about by an imbalance of the muscular forces moving the eye.

Normally both the eyes move equally in conjunction with each other for all direction of gaze and there is no misalignment. The exact cause why squint develops in an otherwise normal child cannot be determined. However, there is a higher chance of developing squint if there is family history of such disturbances. In children, the presence of refractive errors especially if asymmetric between the two eyes, can also lead to the development of squint. Other causes in children may be following trauma or be associated with mental retardation, delayed development or associated with other systemic abnormalities in certain syndromes. In adults major reasons why a squint develops may be due to injury, associated with hypertension and diabetes, brain tumors, thyroid disturbances or associated with infections.
