Abstract

BACKGROUND/AIMS: Conventional time domain optical coherence tomography (OCT) has become an important diagnostic tool to measure retinal thickness in clinical routine. Recently, different models of high-speed, high-resolution frequency domain OCTs have been introduced by various manufacturers. The purpose of this study was to compare 3 commercially available OCT models for retinal thickness measurements in healthy controls. METHODS: OCT scans were performed on 28 healthy eyes with the RTVue-100 FD-OCT (Optovue Inc., USA), the Cirrus HD-OCT (Carl Zeiss Meditec Inc., USA) and the Stratus OCT 3000 (Carl Zeiss Meditec Inc.). Retinal thickness values were calculated and compared between OCT models. RESULTS: Differences in mean retinal thickness measurements between OCT models were statistically significant. Mean retinal thickness measurement with Cirrus OCT, RTVue OCT and with Stratus OCT was 300, 265 and 257 microm, respectively. CONCLUSION: Measurements with different OCT models lead to significantly different retinal thickness values.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
