In this study, we found reduced inner macular DCP in the exotropia group with abnormal binocular vision compared to the control group. We speculate that changes in the DCP may be associated with temporal hemiretinal suppression in the deviated eyes of exotropia subjects [Previous studies have shown that the macular structure and retinal nerve fiber layer (RNFL) thickness were significantly altered in strabismic patients compared to healthy controls using OCT [With the proliferation of medical imaging, OCTA directly manifests a more detailed visualization of retinal morphology and quantification of morphological microvascular metrics. As a non-invasive and effective examination tool, it sheds new light on the investigation of the sequelae of strabismus. In this study, we used OCTA to analyze the RT and capillary plexus in the exotropia group and the control group. We also investigated the difference between the strabismic eyes and the contralateral eyes in the exotropia group. We found that RT had no significant difference, which contributed to the similar SE and AL. This was consistent with the study conducted by Ji H. et al. [Reche-Sainz JA et al. [Compared with the control group, we found that in the exotropia group, SCP was greater in the temporal quadrant in the deviated eyes, and lower in the nasal quadrant in the dominant eyes in the outer macula. The previous reports were almost inconsistent [Oka, M. et al. [Furthermore, Yeo, J. H. et al. [
