Many studies have been published trying to find out some differences in the phenotype of normal‐pressure glaucoma (NPG) and high‐pressure glaucoma (HPG). The authors of these studies mainly focused on the “vascular signs”, the visual field and the optic nerve head (ONH) appearance of these 2 clinical presentations. However the debate is very controversial and several papers have reported that after all there is no difference in clinical presentation between NPG and HPG. In this review we will detail the pros and cons of each theory and we will provide the physician with useful practical tips leaving him/her with the following questions: Is the limit between NPG and HPG so tight? Can we find specific clinical characteristics of the ONH according to the clinical presentation? Should not we concentrate on the erroneous NPG diagnoses, i.e. the nonglaucomatous optic neuropathies?
