Objective: To compare intraocular pressure (IOP) and ocular pulse amplitude (OPA) values determined by Pascal dynamic contour tonometry in primary open angle glaucoma (POAG), ocular hypertension (OH), normal tension glaucoma (NTG) and normal eyes, and evaluate relationship between OPA and glaucoma type. Material and Methods: 120 eyes of 120 patients (30 patients in each of the following 4 groups; POAG, OH, NTG and normal subjects) were included in this prospective non-randomized study. In each group IOP and OPA values were measured and differences between the groups were investigated. Presence of correlation between OPA and IOP or central corneal thickness were evaluated. Results: There was not difference between the groups according to sex (p=0.578). Mean age was different (p=0.001), and POAG patients were older than OH and NTG patients (p=0.001). Corneal thickness was also different (p=0.001), where, it was thicker in OH (p=0.001) than the other groups and thinner in NTG (p=0.001). There was also difference between the groups according to IOP (p=0.001), IOP was higher in OH (p=0.001), and lower in NTG patients (p=0.001). When OPA values were evaluated, it was seen that there was significant difference between the groups (p=0.001), and OPA was significantly higher only in OH patients (p=0.001). Statistically significant correlation was not seen between OPA and IOP or central corneal thickness in each group (p>0.05). Conclusion: OPA was significantly higher in patients with OH where IOP was also higher, but there was not correlation between OPA and IOP or central corneal thickness.Keywords: Glaucoma, intraocular pressure, tonometry, ocular
