Central Retinal Vessel Trunk Dragging in Highly Myopic Eyes

Listen to this summary

The authors aimed to investigate the prevalence and associations of central retinal vessel trunk (CRVT) dragging in highly myopic eyes. They found that CRVT dragging is common in these eyes, with its prevalence significantly increasing with longer axial lengths and greater optic disc-fovea distances, suggesting a relationship between myopic axial elongation and the morphological changes observed in the optic nerve head. The study highlights the potential importance of CRVT dragging in diagnosing optic neuropathies in highly myopic patients.
