Ocular pulse amplitude as a diagnostic adjunct in giant cell arteritis. [PDF]
Eye (Lond), 2015 To develop an algorithm based on the ocular pulse amplitude (OPA) to predict the probability of a positive temporal artery biopsy (TAB) result in the acute phase of suspected giant cell arteritis (GCA).Unilateral TAB was performed and ipsilateral OPA measurements were taken by Dynamic Contour Tonometry.

Ocular pulse amplitude in diabetes mellitus [PDF]
British Journal of Ophthalmology, 2000 The influence of diabetes mellitus on ocular pulse amplitude (OPA), an indirect measure of choroidal perfusion, is unclear.OPA, using the Langham ocular blood flow (OBF) system, applanation intraocular pressure (IOP), systemic blood pressure (BP), heart rate, and haemoglobin (Hb) A(1c) were measured in patients with insulin dependent diabetes mellitus (

Effects of childhood obesity on ocular pulse amplitude and intraocular pressure. [PDF]
Arq Bras Oftalmol, 2023 To assess intraocular pressure and ocular pulse amplitude changes in obese children and adolescents using dynamic contour tonometry.137 cases, 64 obese and 73 healthy children, who were both age-matched and gender-matched, comprised the study population in this cross-sectional study.

Ocular pulse amplitude after trabeculectomy [PDF]
Graefe's Archive for Clinical and Experimental Ophthalmology, 2005 The ocular pulse amplitude (OPA) is the difference between the minimum and maximum values of the pulsatile intraocular pressure (IOP) wave contour. The OPA depends on ocular perfusion and IOP, which are both affected by a trabeculectomy (TE). The aim of this study was to investigate how the OPA changes after TE and whether an early change in OPA can be

Intraocular pressure and ocular pulse amplitude using dynamic contour tonometry and contact lens tonometry [PDF]
BMC Ophthalmology, 2004 Background The new Ocular Dynamic Contour Tonometer (DCT), investigational device supplied by SMT (Swiss Microtechnology AG, Switzerland) allows simultaneous recording of intraocular pressure (IOP) and ocular pulse amplitude (OPA). It was the aim of this
