Wang Y, Wang X, Shi H, et al. - In the present study, the researchers sought to investigate the microstructural properties of the major white matter tracts in constant exotropia (XT) before and after strabismus surgery, and further examine the connection between microstructural alterations and the ocular dominance (OD). They obtained diffusion tensor imaging data from patients with XT before (n = 19) and after (n = 15) strabismus surgery and 20 healthy controls and assessed OD and stereopsis. Microstructural alterations in the visuospatial network tracts after surgery can contribute to the restoration of stereopsis. In addition, the findings of the correlation analysis can suggest that balanced binocular input can be more conducive to the restoration and improvement of binocular visual function, including stereopsis. Thus, to achieve more drastic changes, it may be important to restore normal ocular balance after surgical correction.
