[Accommodation insufficiency in children].

Insufficiency of accommodation in children is often misdiagnosed, and particularly in preschool age. Subject if symptoms are unspecific, asthenopia, difficulties in nearwork, and for concentration. Differential diagnosis must be done between dyslexia, non refractive accommodative esotropia with high AC/A. In some cases we can't exclude the possibility of myasthenia even if this subject is still in discussion. The authors report two clinical cases of hypoaccommodation in children.
