Enlargement of the blind spot without optic disc edema has been reported in
patients with no other ocular findings (acute idiopathic blind spot
enlargement) and in patients with multiple evanescent white dot syndrome.
We describe three patients with multifocal choroiditis who developed acute
symptomatic enlargement of the blind spot. All three patients were young
women in excellent health. During the course of the blind spot enlargement,
the appearance of the optic nerve remained normal. We demonstrate that
acute enlargement of the blind spot without disc edema occurs in patients
with multifocal choroiditis. This enlargement is likely due to
peripapillary retinal dysfunction. We speculate on the association of
multifocal choroiditis with acute idiopathic blind spot enlargement and
multiple evanescent white dot syndrome.
