Children's vision key to education

Education is of increasing

importance in our booming and technologically advanced economy and is

essential for young people who hope to succeed in today's world.

A child's inability to read with comprehension can be a major hurdle

to his or her education. A child's reading difficulty and inability

to keep up with his or her classmates or to advance can be due to a visual

deficiency such as myopia, hyperopia or astigmatism and not due to a lack

of motivation or interest.

A child's visual status is not fully formed at birth but continues

to develop until the age of 6. Because of this, eye care professionals

such as those at the Fayette Eye Clinic recommend a cycloplegic examination

- an examination with dilating eye drops - for children at age

3 as an initial base line examination to rule out visual deficiency or

eye pathology.

Of course, any infant who is having difficulty seeing large objects or

a child with a protracted turning in or turning out of the eye should

be seen promptly, no matter what age level.

One of the serious consequences of an untreated strabismus condition,

or a turning in (esotropia) or turning out (exotropia) or the eye, is

the resulting suppression of the double image by the visual center in

the brain and the resulting amblyopia. Amblyopia is a condition of the

eye in which there is no visible eye lesion, yet the vision in the involved

eye is subnormal and will remain that way throughout life unless treated

aggressively.

The most frequent eye deviation is esoptropia. Initial treatment consists

of patching or occluding the straight or fixating eye so that the deviating

eye will be forced to straighten to see objects viewed.

A cycloplegic refraction is mandatory for infants, children and teenagers.

A cycloplegic is an eye drop to eliminate accommodation, which is an automatic

action of the eye to contract the human crystalline lens and to turn the

eye muscles in. Without cycloplegic drops the child's visual deficiency

will not be fully detected nor will the turning in or out of the eye be

corrected.

If the child's eyes show farsightedness (hyperopia) or nearsightedness

(myopia) then corrective glasses are prescribed for full or part-time

wear with regular visual and eye muscle checkups made. If the eyes are

straight with the wearing of corrective glasses then conservative management

is the usual treatment of choice. If on the other hand there is residual

turning of the eyes with glasses on, then corrective eye muscle surgery

is recommended, which consists of weakening or strengthening the eye muscles

which are causing the turn.

Many students complain of headaches which are not relieved by the usual

anti-headache remedies and may be due to straining to see the board because

of myopia or straining to read caused by hyperopia. Another common cause

of headaches is astigmatism or irregular image. These three conditions

and the headaches can be relieved by the wearing of full-time or part-time

glasses or by contact lenses.
