My daughter is 9 years old. Her glasses prescription is -7.50 in R eye and -
7.75 in left eye. We only picked up that she needed glasses when she was
almost 5 years old -her first prescription was about -6.5 . Her
prescription has been -7.5 /7.75 for last few years. Her problem is that
even with this prescription -she can only read the first three lines or so
of an eyesight test. Her retina has been examined etc -and he says that she
is one of those people who are unable to have good vision even with the
best /strongest glasses that suit them.
He says there is no treatment for this -just wearing glasses . When she
gets older -contacts woulkd help a little ..Has anyone experienced this
situation -and is there any possible treatment for our daughter.
We dont want to give up on her -but her (eminent) opthalmologist says there
is nothing to be done -except glasses/contacts.

Unfortunatly, even though your daughter's refractive error was corrected
early on, her eyes (or connections within the visual areas of the brain
to be more accurate) haven't developed as normal. When both eyes are
involved this is called "bilateral refractive amblyopia".

Your health professionals are correct in advising you that her wearing
glasses along with encouraging detailed visual tasks is the best course
of action for her. The hope is that supplying a clear visual image can
aid further development of the visual system. This is usually effective
until about 8-10 years old and a little longer in some cases.

As far as contact lenses are concerned, they may help give better vision
because they don't minify images like glasses do, thus making smaller
objects easier to see.

What type of things do you mean by "detailed visual tasks"-for bilateral
refractive amblyopia? Our ophhamologist never said anything about anything
loike this (he just says "wear the glasses")

Also , I see from websites that there are treatments for "amblyopia" such
as "light therapy etc"...seems like quite a lot of work is done in France ,
Europe.
Is there anything like this (ie other than wearing glasses + the "detailed
visual tasks" that MIGHT help our daughter.Anyone know anything that is
worth  us  looking into ?

She has had her retina examined under anaestetic and had electronographic
examination- no abnormalities found.

More for younger kids really, but behavioral optometrists and vision
therapists often prescribe tasks requiring good vision e.g. drawing within
two closely placed lines and the like. However these usually are in cases
of unilateral amblyopia i.e. one lazy eye with the good eye being covered
with a patch/blurred with atropine.

There are usually ongoing studies into these sort of things, however I
don't know of any clinically significant trials of treatment for bilateral
amblyopia. From what you've posted it seems that your daughter is being
looked after and she has been given the best treatment.

It seems like she has had a thorough set of examinations regarding the
health of her eyes i.e. there seems to be no underlying problem with the
retinal cells and structures so it is a true amblyopia.

Dr. Leukoma - 31 May 2005 13:44 GMT
An unfortunate situation, as well as unusual.  Bilateral amblyopia is
uncommon with simple myopia, i.e. none or very little astigmatism.  I
did see a study in which approximately 25% of children with high myopia
had some other problem, such as retinal dystrophy.

I wonder if our pediatric OMD will comment?
