In this study, 3D modelling software was used to visualise the orbital pulleys and create educational content to facilitate visual understanding of this system. Input of measures were from published data on quantitative anatomy of the globe and extraocular muscles (eoms), eom paths from MRI scans and cadaveric measurements. Video material is available at https://zenodo.org/records/14897453. The results are given for orbital mode (axial length, muscle attachment sites, muscle width and lengths), orbital pulley model (pulley sleeve, pulley array and pulley sling), connections between orbital pulleys, eoms and Tenon’s fascia. The authors acknowledge limitations of using non-validated data from MRI scans and lack of motor function evaluation. However, there is potential for this to be a useful education resource.
