Post anterior levator resection
This 13 year-old boy has had a left anterior levator resection for congenital ptosis. 
He is pleased with the result but on down-gaze there is failure of the left eyelid to
relax resulting in an asymmetrical lid height. This feature is common in patient with
congenital ptosis due to the presence of dystrophic levator and can become 
exacerbated following surgery. The patient and parents should be told about this potential problem to avoid unhappiness with an otherwise satisfactory surgical outcome.
