Abstract Details

Purpose:

To measure the inter- and intra-observer repeatability and reproducibility of choroidal thickness measurements performed by enhanced depth imaging of spectral-domain optical coherence tomography (EDI-OCT) in randomly selected subjects using two different protocols.

Setting:

1st Department of Ophthalmology, Aristotle University of Thessaloniki, AHEPA Hospital, Thessaloniki, Greece

Methods:

Twenty subjects of the Thessaloniki Eye Study data base were randomly selected. The participants underwent EDI-OCT and the choroidal thickness was measured on EDI images using two different protocols. All images were assessed by two examiners independently in two sessions in different days.

Results:

The interobserver ICC for average choroidal thickness was 0.944. The average ICC for Central, C min and Cmax choroidal thickness were 0.899, 0.863 and 0.955 respectively. The interobserver ICC for average choroidal volume was 0.932. Intraobserver repeatability ICC for grader 1 ranged between 0.913 and 0.994 and for grader 2 between 0.925 and 0.972.

Conclusions:

Choroidal thickness measurements by EDI-OCT showed a high inter- and intra-observer reproducibility
