An 8-year-old girl with a history of mild amblyopia who had occlusion
therapy, but her anisocoria went unnoticed, was studied. Old photograp
hs of the patient were reviewed and a 0.1% pilocarpine test was perfor
med. Review of her old photographs suggested that she had anisocoria a
t least since she was 3 years old. The 0.1% pilocarpine test confirmed
a diagnosis of Adie's syndrome. In light of this case, it must be kep
t in mind that though rare, Adie's syndrome can be encountered in earl
y childhood.
