THERAPY OF STRABISMUS<br />

long sighted and requires glasses to control the<br />
squint but refuses to wear glasses, initial use <strong>of</strong><br />
mydriatic drops daily will make the vision<br />
blurred without glasses. In this circumstance<br />
acceptance <strong>of</strong> glasses is made easier.<br />
Some young children enjoy wearing an eye<br />
patch if they feel they’re playing a character like<br />
a pirate (Figure 7.2). School-age children can be<br />
unkind about difference, calling children with<br />
glasses “four-eyes”, calling children with squint<br />
“dumb”. We’ve even known children to refuse to<br />
sit with children with visual problems. In<br />
kindergarten children are more accepting, and<br />
kindergarten teachers can do much to explain<br />
and assist the child receiving treatment. From<br />
age 6 onwards it becomes more difficult with<br />
larger classes and students are more difficult to<br />
control. In some cases children won’t wear<br />
glasses, but more frequently they flatly refuse to<br />
wear occlusion. In such cases it is our strongly<br />
held belief that occlusion should be part time<br />
and carried on out <strong>of</strong> school hours.<br />
With this regime we have plenty <strong>of</strong> experience<br />
<strong>of</strong> recovery <strong>of</strong> vision, including amongst children<br />
brought for second opinion because <strong>of</strong> refusal to<br />
accept occlusion during school hours. In young<br />
and also older children, the near vision test charts<br />
matching tests can be photocopied and parents<br />
encouraged to check progress <strong>of</strong> the occlusion<br />
tests at home. Even the letters in the phone book<br />
can be used. Children wearing glasses <strong>of</strong>ten<br />
object to occlusion if the occluder is stuck to the<br />
face. This can be avoided by the use <strong>of</strong> paper<br />
occluders attached to the glasses.<br />
With adults, the eye health pr<strong>of</strong>essional team<br />
is smaller. The strabismus specialist treating the<br />
adult may not need an assistant because the<br />
adult should be more in control <strong>of</strong> their anxieties<br />
and should be more cooperative. However,<br />
unlike children, they may be demanding in a<br />
different way, depending on their expectations.<br />
They may seek cosmetic improvement, relief <strong>of</strong><br />
double vision or seek restoration <strong>of</strong> binocular<br />
vision when this has been absent since<br />
childhood. Recent onset <strong>of</strong> symptoms in<br />
strabismus present since childhood are unlikely<br />
to be related unless there is decompensation, for<br />
example in a case <strong>of</strong> superior oblique paresis that<br />
has previously been fusing.<br />
Management <strong>of</strong> amblyopia in strabismus<br />
Management <strong>of</strong> strabismic amblyopia is a<br />
critical part <strong>of</strong> care <strong>of</strong> the strabismic infant or<br />
child. Strabismic amblyopia has a critical period<br />
more extended than in pattern deprivation<br />
amblyopia, though less than that in refractive<br />
amblyopia. It occurs during development when<br />
there is plasticity <strong>of</strong> the brain. Simple occlusion<br />
