Squint or strabismus is cross-eyes.It is defined as a condition in which the eyes deviate (turn) when looking at a particular object.Eye doctors generally look for the presence of a strabismus when looking at: distance (20 feet or more); near (16 inches for an adult and 13 inches for a child); lateral and vertical directions (up, down, left, or right).
When the eye turn occurs all the time, it is called constant strabismus. When it occurs only some time, it is called intermittent strabismus.With intermittent strabismus, the eye turn might be observed only occasionally, such as during stressful situations or when the person is ill. The timing and type of treatment depend on the type of condition.
How common is this disorder?
It is a common eye problem, especially in children. However, it is also known to occur in adults. It is seen in three-five per cent of normal population. It can occur due to a variety of causes, such as hereditary, muscle weakness, poor vision, or any disease occurring within the eye, such as cataract in children.
When should one suspect it?
I The most important sign is when eyes are not positioned straight. When a child turns his face or tilts head to see in a particular direction. I Closes one eye in bright sunlight.
What happens if untreated?
Amblyopia (lazy eye) is a gradual deterioration of vision in an otherwise normal eye. The risk is greater in children below 10 years of age. Once the eye becomes lazy, it tends to be irreversible, unless intervened appropriately.
How does squint correction help?
Straightens the eyes (cosmetic), restores vision, preserves binocularity (To use both eyes simultaneously).
Treatment - What is the treatment For squint
Orthoptics:
It is a medical term for the eye muscle training programs. Orthoptics treat muscle problems only in regard to strength and is usually done using a special machine called the synaptophore. Customarily, all squint patients, especially those whose axis of deviation is not too much, are given a trial of exercises.
Surgery:
Squint surgery is reserved for those whose angle of deviation is great or those who have had a trial of exercises and found inadequate improvement.
