The comitant exotropia (CE) is a common eye disease characterized by outward deviation of the eyes and impairment of stereovision. In this study, we aim to investigate the altered functional connectivity (FC) in patients with CE using resting-state fMRI. The CE patients showed significantly less FC between the left V1 and left lingual gyrus/cerebellum posterior lobe, right MOG, left precentral gyrus/postcentral gyrus and right IPL/postcentral gyrus; as well as less FC between right V1 and right MOG (BA19, 37). Our findings show that CE involves defects in the possessing of stereovision, such as fusion, spatial processing, visual recognition, and oculormotor.
