[Ocular pulse amplitude and local carbonic anhydrase inhibition].

Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 1997
Ocular perfusion is increasingly being discussed in the pathogenesis of glaucoma. The present study was designed to investigate ocular pulse amplitude (OPA) in primary open-angle glaucoma (POAG) patients with elevated intraocular pressure (HTG) and non-glaucomatous controls (CTL) following topical application of the carbonic anhydrase inhibitor ...

[Ocular pulse amplitude in ocular hypertension and open-angle glaucoma].

Ophthalmologica. Journal international d'ophtalmologie. International journal of ophthalmology. Zeitschrift fur Augenheilkunde, 1998
The present study was designed to investigate choroidal perfusion in primary open-angle glaucoma patients with statistically elevated (HPG) and statistically normal (NPG) intraocular pressure (IOP) and in ocular hypertensive volunteers (OHT) before and after application of topical antiglaucomatous drugs.

Intraocular pressure and ocular pulse amplitude variations during the Valsalva maneuver

Graefe's Archive for Clinical and Experimental Ophthalmology, 2010
To evaluate the effect of the Valsalva maneuver (VM) on short-term variations of intraocular pressure (IOP) and ocular pulse amplitude (OPA) values in healthy, young, male subjects.IOP and OPA values were measured before and during VM by Pascal dynamic contour tonometer (DCT) in 55 eyes of 55 healthy male volunteers aged 20 through 27 years.Mean IOP ...

Color Doppler Imaging and Ocular Pulse Amplitude in Glaucomatous and Healthy Eyes

European Journal of Ophthalmology, 2009
Purpose To determine factors influencing color Doppler imaging (CDI) measurements, to compare retrobulbar flow velocities between patients with glaucoma and healthy controls, and to describe the correlation between CDI and ocular pulse amplitude (OPA).

An evaluation of the effects of eyeball structure on ocular pulse amplitude in healthy subjects

International Ophthalmology, 2012
To evaluate the effects of eyeball structure on ocular pulse amplitude (OPA) measured using dynamic contour tonometer (DCT). In 86 eyes of 43 healthy subjects, we measured OPA and intraocular pressure (IOP) with DCT (DCT-IOP), IOP with Goldmann applanation tonometry (GAT-IOP), central corneal thickness (CCT), corneal thickness 2 mm (2 mmCT) and 4 mm (4

Ocular Pulse Amplitude in Patients with Asymmetric Primary Open-Angle Glaucoma

Current Eye Research, 2011
To evaluate ocular pulse amplitude (OPA) using the dynamic contour tonometer (DCT) in patients with asymmetric primary open-angle glaucoma (POAG) and asymmetric intra-ocular pressure (IOP).The participants consisted of 48 patients (96 eyes) with asymmetric POAG. Three measurements of IOP and OPA were taken using DCT. The diagnosis of asymmetry required

Effects of cigarette smoking on choroidal and retinal thickness and ocular pulse amplitude

Cutaneous and Ocular Toxicology, 2014
In our study, we aimed to show the effects of smoking on choroidal thickness and ocular pulse amplitude. It is known that the anatomy and physiologic functions of the choroid is important in ocular diseases like glaucoma and age-related macular degeneration.

The Effect of Ocular and Systemic Factors on Ocular Pulse Amplitude

2014
Objective: To assess the effect of ocular and systemic factors on ocular pulse amplitude in patients with primary open angle glaucoma. Materials and Methods: Fifty eyes of 50 primary open angle glaucoma patients were included in this study. Patients underwent routine ophthalmologic examination with intraocular pressure and ocular pulse amplitude ...
