Squint (strabismus)
Condition in which a person cannot align both eyes
simultaneously. An eye can in, out, up or down. When the eye turns in, it is
called - esotropia, when eyes turn out, it is called - exotropia, when the eye turns
down, it is called a hypotropia and when the eye turns up, it is called -
hypertropia.
Causes
·
Weakened muscles or abnormal nerve
impulses in the eye muscles.
·
Heritage.
·
Blurred or deficient vision, for any
reason, such as cataracts, refractive errors, etc.
·
Strabismus can accompany some systemic
illnesses like diabetes, high blood pressure, multiple sclerosis, myasthenia
gravis or thyroid disorders.
What will happen if the child has cross eyes?
Strabismus can lead to a "lazy eye" or
amblyopia, in which the vision in the eye squinting decreases. Amblyopia is
best treated at a younger age. Therefore, it is best to consult your
ophthalmologist as soon as you notice any abnormality in the eyes.
There may be a faulty depth perception.
Psychological development and inadequate personality
due to low self-esteem.
Diagnosis
The evaluation for suspected strabismus usually
includes a medical and visual history and a test for visual acuity (how well
one sees with each eye). The diagnosis of strabismus is best made with a
careful eye examination with the ophthalmologist.
The most common visible sign of Strabismus is that the
eye does not appear straight. Sometimes, a child will squint or close one eye
in bright sunlight. Faulty depth perception may be present. They may tilt their
heads in a specific direction in order to use their eyes together.
It is important to consult an Ophthalmologist if your
child displays these symptoms to determine the appropriate treatment.

Prevention
Children
should be monitored closely during infancy and the preschool years to detect
potential eye problems, particularly if a relative has strabismus. Early
detection, accurate diagnosis, and proper treatment can cure strabismus. It is
recommended that all children be screened for eye health before age 6 months
and again between 3 and 5 years of age by a pediatrician or an ophthalmologist.
Routine
vision screening for young children includes testing for strabismus, usually
using the light reflex for infants, and cover testing for preschool-age
children.

Treatment
The primary
goal of treatment is to preserve or restore as much visual function as
possible.
Treatment of
squint varies depending on the exact type and cause of the strabismus. After a
complete eye examination, including a detailed study of the inner parts of the
eye, an ophthalmologist can recommend appropriate optical, medical or surgical
therapy.
Nearly 40%
patients with squint can be cured by spectacles and/or eye exercises. However,
a large majority require surgical treatment. The squint operations are very
safe and should be done at the earliest. Generally, if the eyes are not aligned
for more than 6 months in a child, irreversible damage to the three-dimensional
vision occurs, which is only partly reversible. Squint surgeries are performed
successfully even in children as young as 4 months.
