Children with congenital ptosis may develop amblyopia, particularly
if the ptosis is unilateral and occludes the pupil. These children
should be referred to a pediatric ophthalmologist to determine whether
surgical treatment is indicated. Mild-to-moderate ptosis usually
is not an immediate threat to vision, but evaluation is important
due to its possible association with systemic diseases. Children
with new onset of acquired ptosis, particularly if associated with
signs of third nerve palsy or orbital mass, should be referred promptly
for further evaluation.

What Shouldn’t
Be Missed

Acquired ptosis may be the initial sign of a serious underlying
disorder, such as a third nerve palsy or an orbital tumor. Prompt
diagnosis improves the outcome of most of these disorders (Table
14–1).
