Comparison of Neuroretinal Rim Area Measurements Made by the Heidelberg Retina Tomograph I and the Heidelberg Retina Tomograph II
PURPOSE To investigate the agreement between neuroretinal rim area (RA) measurements using the Heidelberg Retina Tomograph I (HRT Classic) and Heidelberg Retina Tomograph II (HRT II). To compare apparent RA changes in follow-up series of HRT II topographies when using either an HRT Classic or HRT II mean topography as baseline. DESIGN Cross-sectional study and "no-change," short time series s...
متن کاملFactors affecting the test-retest variability of Heidelberg retina tomograph and Heidelberg retina tomograph II measurements.
AIMS To evaluate the test-retest variability of stereometric parameter measurements made with the Heidelberg retina tomograph (HRT) and Heidelberg retina tomograph-II (HRT-II), and to establish which parameter(s) provided the most repeatable and reliable measurements with both devices. An investigation into the factors affecting the repeatability of the measurements of this parameter(s) was con...
متن کاملSCIENTIFIC REPORT Improving the repeatability of Heidelberg retina tomograph and Heidelberg retina tomograph II rim area measurements
Aims: To devise and test strategies for improving Heidelberg retina tomograph (HRT and HRT-II) rim area (RA) repeatability and assess the benefit of the strategies in time series of HRT images. Methods: The effect of the standard and 320 mm reference planes and image quality on RA repeatability was assessed in a test-retest HRT image dataset from 74 subjects. A longitudinal HRT image dataset fr...

متن کاملRelationship between short-wavelength automatic perimetry and Heidelberg retina tomograph parameters in eyes with ocular hypertension.
AIM To compare and correlate optic nerve head parameters obtained by Heidelberg retina tomograph (HRT) with short-wavelength automatic perimetry (SWAP) indices in eyes with ocular hypertension (OHT). METHODS One hundred and forty-six patients with OHT included in the present study. All subjects had reliable SWAP and HRT measurements performed within a 2wk period. The eyes were classified as n...
