Purpose
Duane syndrome (DS) belongs to a group of congenital retraction syndromes, the incidence of which varies between 2% and 4% in patients with strabismus. In most cases the damage is unilateral, but it manifests as bilateral in about 20% of cases. According to the classification of Huber, type III DS exhibits a limitation of abduction and adduction.
Methods
We report the case of a 5-year-old boy from Eastern Europe who was taken to the hospital because he was unable to move both eyes horizontally from birth and had not been previously seen by an ophthalmologist.
Results
The examination showed inability to abduct and adduct bilaterally, with narrowing of the palpebral fissures on attempted adduction. The patient was diagnosed with bilateral type III DS.
Conclusions
Treatment is individualized on a case-by-case basis. For our patient, monitoring by way of regular checkups was chosen, with the parents rejecting surgery for now.
