Clinical characteristics of group 1 (dislocation of LR)
| Patient, sex, age (years) | Axial length of the globe (mm) | Preoperative deviation in 5 metres (prism and cover test or corneal reflex) | Maximum ductions, abduction/ elevation | Dislocation of the lateral rectus (shifting from the horizontal meridian (mm)) | Surgical procedure | Postoperative deviation in 5 metres (prism and cover test or corneal reflex) | Maximum ductions abduction/ elevation/ adduction of the operated eye postop | ||||||||

Initially horizontal deviation: + = esodeviation; because by chance in all unilaterally affected subjects the lateral rectus of the left eye is shifted, a vertical deviation occurs in the left eye—that is, a left eye hypotropia or −VD.
↵Measured in the mid orbital region on the coronal MRI scans; the described surgical procedure was performed on left or right eye as indicated by bold letters.
↵R&R = recession of MR (first number (mm)) and resection of LR; f = fixation of LR in the physiological meridian; supra = supraposition of the insertion site of the resected LR; vert R&R = recession of inferior rectus and resection of superior rectus.
↵Not only the path of the LR in the mid orbital region, but also the insertion site was shifted towards the inferior rectus in these cases with previous eye muscle surgery; the measured values refer to the shifting of the muscle path in the mid orbital region.
