Abstract
Congenital fibrosis of the extraocular
muscles (CFEOM) is a congenital
ocular motility disorder that
manifests as restrictive ophthalmoplegia
with ptosis.1 Synergistic divergence
(SD) is a deficit of adduction
associated with simultaneous
bilateral abduction on attempted
gaze into the field of action of the affected
medial rectus muscle.2 There
has been no pathologic report of SD;
however, magnetic resonance imaging
showed that in 2 patients with CFEOM and SD, the oculomotor
nerve was hypoplastic bilaterally and
the abducens nerve was absent on
the side exhibiting SD.3 To our
knowledge, bilateral deficit of abduction
associated with simultaneous
bilateral adduction on attempted
gaze into the field of action
of the lateral rectus muscles, the
counterpart of SD, has not been previously
reported.
