Vertical position of the central retinal vessel in the optic disc and its association with the site of visual field defects in glaucoma

The optic nerve head (ONH) presents with characteristic deformations in glaucoma, and ocular structures that consist of the ONH change their shape along with it. The lamina cribrosa (LC) is one of these structures,1-4 and it is reported to exhibit deformations such as posterior displacement,5,6 posterior migration at its insertion point,7,8 and thinning.9 Enlargement of the ONH area has also been reported in glaucoma, including expansion of the Bruch's membrane opening (BMO) and the anterior scleral canal opening.
