What is Squint?
Squint is misalignment of eye where two eyes are pointed in different directions. Though it is a common condition seen among 4 of 100 children it can appear in adults. The deviation can be in any directions- inwards, outwards, upwards or downwards. The misalignment may be permanent, noticeable always or it may be temporary, seen occasionally.

Causes of Squint?
Squint may be caused by any of the following:

  • Weakened muscles or abnormal nerve impulses to the eye muscles
  • Heredity
  • Blurred or poor vision 'Conditions inside the eye such as cataract

 

Symptoms of squint
Main complaint of patient is that the eyes are not straight. Sometimes, a youngster will squint or close one eye in bright sunlight. Faulty depth perception may be present. Some children turn their face or tilt head in a specific direction in order to use their eyes together.

Treatment
Patient often gets the false impression that child may "outgrow" the problem. If a child has two eyes pointed in different directions, eye examination by ophthalmologist is necessary to determine the cause and to begin treatment. The goals of treatment are to preserve vision, straighten the eyes and to restore binocular vision. Treatment of squint depends upon the exact cause of the misaligned eyes. It can be directed towards unbalanced muscles or other conditions, which are causing the eyes to point in two different directions. After a complete eye check-up, including detailed study of the inner parts of the eye, an ophthalmologist can recommend appropriate optical, medical and surgical therapy.

Non Surgical Treatment
Some squints are caused because of refractive errors. For such cases, wearing prescribed glasses can correct squint completely.

Surgical Treatment
Most patients require surgical corrections. Surgery is done
under anaesthesia, in children and under local anaesthesia in adults.
