[A clinical analysis of 25 cases with Duane's retraction syndrome combined with congenital crocodile tears].
OBJECTIVE
To analyze the clinical manifestations of Duane's retraction syndrome (DRS) combined with congenital crocodile tears or gustatory-lacrimal reflex.


METHODS
Twenty-five cases of DRS associated with congenital crocodile tears were retrospectively summarized. The clinical features, including sex, age at first visit, chief complaints, laterality, types of DRS, features of abnormal lacrimation and its associated ocular and non-ocular anomalies were analyzed.


RESULTS
There were 8 males and 17 females with a male-to-female ratio of 1:2. Fifteen cases had binocular involvement and the remaining 10 cases were monocular involvement. In general, the association of the abnormal lacrimation and eye movement disorder in unilateral cases was ipsilateral, while in bilateral cases the abnormal lacrimation and the movement disorder were also bilateral except 3 cases of bilateral DRS with monocular crocodile tears and one case of unilateral DRS with binocular crocodile tears.


CONCLUSIONS
Clinically, cases with Duane's syndrome combined with crocodile tears are relatively few. That sufficiently pay attention to and master its clinical characteristics is the basis for its correct diagnosis.
