Repeatability and reproducibility of optic nerve head topography using the retinal thickness analyzer

Abstract

Repeatability and reproducibility of the optic disk topography analysis using the RTA reveals a high variation, and should, therefore, be interpreted carefully for glaucoma diagnosis and for monitoring the disease.

Comparison of optic nerve head topography in healthy adults using a Heidelberg retina tomograph and retinal thickness analyzer

“…Recently, Hoffmann et al [12] assessed the repeatability and reproducibility of optic disc topographic parameters measured by RTA and found a large overall variation in optic nerve head measurements. Repeatability, expressed as a percentage of total variation in their study, was greater than 10% for most of the topographic parameters, and was only lower than 10% for the disc area (3%) and maximum cup depth (8.2%).…”

Repeatability and reproducibility in med labs: a procedure to measurement system analysis

“…Indeed, GR&R studies are widely used in measurement system analysis. They can be found in different fields such as industry [1,2], pharmaceutical applications [3], healthcare [4][5][6], microcontrollers [7] veterinary science [8], environment [9], optics [10] and many others.…”
