Central retinal vascular trunk deviation in unilateral normal-tension glaucoma.

<h4>Purpose</h4>To investigate whether the position of the central retinal vascular trunk (CRVT), as a surrogate of lamina cribrosa (LC) offset, was associated with the presence of glaucoma in normal-tension glaucoma (NTG) patients.<h4>Methods</h4>The position of the CRVT was...
