The Paediatric Ophthalmology & squint Department at Prakash Netra Kendr (PNK) deals with eye problems in children. Adult patients suffering from squint anddouble vision are also examined and treated effectively.
Children may not complain if they do not see out of one or both eyes. Sometimes the only clue may be poor performance in School, as well viewing the blackboard at a very close distance. Hence all children need an eye exam at the time of starting Schooling.Of the eye problems in children, the most important are refractive errors,
squint and amblyopia. Squint is not a sign of good luck. It affects your child's vision and appearance
Loss of vision is preventable in children if squint is treated as early as possible, preferably before 2 years of age
As the child grows older, it becomes more difficult to treat squint and regain the lost vision. However, cosmetically straightening the eye is possible at any age Refractive error or the need for glasses is the single most important cause of vision impairment in children. This may lead to permanent deficiency in vision if not detected and treated early.
Squint is a misalignment of the eye where the two eyes are pointed towards different directions. The misalignment may be constant for a few, while it may be intermittently occurring for some others. The deviation of the eye may be in any direction - inward, outward, upward or downward. If the child is not treated at the appropriate time, a condition called amblyopia occurs, which eventually leads to permanent loss of vision
Causes of Squint
Weakness of the eye muscles or problem with the nerves in the eye muscles
Blurred or poor vision caused due to cataract, corneal scars, glaucoma,
Refractive errors, optic nerve disease, retinal disease, tumors of the eye etc.,
Symptoms of Squint
One eye or both eyes point to different directions
Children can have defective vision in one eye or both eyes
Children with squint, sometimes close one eye in bright sunlight
Some children turn their face or tilt their head in a specific direction in order to use their eyes together
Children sometimes experience double vision or confusion Treatment
Squint due to refractive errors is corrected by prescribing suitable spectacles
Before Surgery After Surgery
Surgical treatment is given to the child based upon the improvement in vision by spectacles correction and patching therapy. The misaligned eyes can be straightened through surgery. In this surgery, the muscles are detached from their original insertion and shifted to a different spot. The amount of shift is based on the measurement done with special prisms.
Surgery is usually done under general anaesthesia for children. It is ensured tha the child is free from any illness like fever, common cold, cough etc., for subjecting to general anaesthesia
Surgery is done either on both eyes simultaneously or one eye at a time
The surgery is done on the white portion of the eyeball
The eyeball is not opened
Stay in the hospital is only for a day after the surgery
Treatment does not stop with surgery. Glasses may have to be continued to maintain clarity of vision. Patching therapy may be needed to be continued for
some time after the surgery
Lazy eye or amblyopia is the term for poor vision in one or both eyes. It can result from refractive error, squint or several other causes. This needs to be identified and treated at an early age to recover vision.
Infants born prematurely are at risk for developing Retinopathy of pre-maturity (ROP) which may lead to permanent blindness.
Cataract (opacification of the lens) can occur in children. This may be present since birth or result from injury. The treatment involves surgical procedures but very often treatment of lazy eye. 5 months old child with both eye congenital cataract
same child after both cataract surgery
After cataract surgery Glasses and amblyopia treatment is must
A child with any of the following needs to have a complete eye examination
Poor performance in School
Viewing objects at a very close distance
Family history of eye problems or wearing glasses
There are several causes of double vision and squint in adults as well. These are
managed by exercise, special glasses, and eye muscle surgery when required
