Purpose: To investigate the relationship between oculomotor skills, phorias, and visual symptoms in pediatric population aged 5 to 8 years. Methods: A cross-sectional study was conducted with 120 children, divided into three age groups. Each participant underwent a full optometric examination, including the Maddox test for dissociated phoria, and the Northeastern State University College of Optometry (NSUCO) and Developmental Eye Movement (DEM) tests for oculomotor function. In addition, the Convergence Insufficiency Symptom Survey (CISS V-15) questionnaire was administered to assess visual symptoms. Results: The prevalence of binocular and oculomotor dysfunctions varied by age and sex. Differences in saccadic and pursuit eye movement performance were observed between groups. Older children showed patterns of association between phoria measurements, oculomotor performance, and possible visual symptoms, particularly in girls over 6 years of age. Conclusions: This study provides additional descriptive data for the pediatric population and highlights that oculomotor dysfunction and phoria frequently coexist. Symptom scores measured by the CISS V-15 tended to increase with age. The results should be considered preliminary and potentially hypothesis-generating, pending the future availability of a validated questionnaire to assess phoria-related symptoms in children from 5 years of age. Overall, this study underscores the importance of comprehensive binocular vision assessments in school-aged children.
