Unilateral congenital ptosis due to plexiform neurofibroma, causing refraction error and secondary amblyopia.

An 8-year-old boy with congenital ptosis of the right upper eyelid due to plexiform neurofibroma was operated on because of a rapidly worsening of his ptosis. Only partial removal of the tumor was possible. A hypermetropic astigmatism of the right eye was caused by the condition of the upper lid, with secondary amblyopia. This finding suggests that in cases of congenital ptosis the presence of a lid tumor must be suspected. Such a tumor causes ptosis and this can lead to refraction error and amblyopia.
