The evaluation of the optic nerve is an essential part of any ocular health examination. The structure and integrity of the neuroretinal rim must be assessed, as well as the presence of adequate optic nerve perfusion. The presence or absence of distinct disc margins is noted as it is an essential clue in determining the etiology of disc swelling and/or suspected papilledema. Frequently, the optometrist is faced with very subtle findings and is forced to decide whether these represent normal variations or something that warrants an emergent workup and referral. In such cases, the most helpful element of the examination is the presence or absence of a spontaneous venous pulse (SVP). To understand the clinical and physiologic importance of the SVP, it is important to recall the course of the optic nerve (ON). The ON runs from the retina towards the optic chiasm and is classified into four segments. The first is the intraocular segment, which measures only 1mm in length and is evident on r
