Comparison Between Parental Observations and Clinical Evaluation Findings in Korean Pediatric Patients With Intermittent Exotropia.

PURPOSE To compare parental observations with the clinical evaluation findings in pediatric patients with intermittent exotropia and evaluate the clinical factors associated with the parental observations. METHODS This prospective study included either one or both parents of pediatric patients with intermittent exotropia who visited the clinic between January and May 2019. The parental observations were assessed through a questionnaire that included questions on the age of onset, usually deviated eye, degree of awareness, and frequency of exotropia. These findings were compared with those of the clinical evaluations, including the amount of ocular deviation and level of control. RESULTS A total of 100 parents (mean age: 39.7 years; 78 women) of 95 pediatric patients (mean age: 8.2 years; 47 girls) with intermittent exotropia participated in the study. The parental observation and clinical evaluation findings on the usually deviated eye showed good concordance (74%). The degree of parental awareness did not show any association with the amount of deviation. However, it showed a statistically significant increase associated with the worsening level of distance control (P = .04). The parental observations of the frequency of exotropia significantly increased with the worsening of the level of near (P = .037) and overall (P = .019) control. CONCLUSIONS Parental observations are more likely to correlate with the level of control than with the amount of ocular deviation in pediatric patients with intermittent exotropia.
