Objective:To understand the characteristics of rapid naming in exotropia children, and to analyze the influence of clinical indicators related to exotropia on the rapid naming.

Methods:A total of 45 exotropia children were recruited according to the diagnostic criteria of consensus of strabismus classification experts (2015) from the Zhongshan ophthalmic center as the case group, and 45 children of the same age, gender and parental educational status were recruited as the control group without any ocular diseases. All children were evaluated the ability of the rapid naming by classical rapid naming test.

Results:The letter rapid naming time of children with exotropia was longer than that in control group [(26.87±10.18)(21.98±7.29)s], and the difference was statistically significant (t=2.73, P=0.01), however there was no significant correlation between strabismus degree, symptom duration, AC/A ratio, disease classification, simultaneous vision, the near stereopsis, the far stereopsis and the letter rapid naming in the clinical indicators of exotropia (r=-0.16, 0.23, 0.20, 0.06, 0.09, 0.05, 0.20, P>0.05).

Conclusion:Rapid naming might be impaired among children with exotropia, with no significant correlation between this defect and its clinical indicators.
