Purpose

To study the interobserver agreement for the detection of optical coherence tomography (OCT) features of diabetic macular edema (EMD) in clinical practice näive patients.

Setting/Venue

Ophthalmology Department. University Hospital of La Candelaria. Tenerife. Canary Islands. Spain.

Methods

A consecutive retrospective analysis of all näive patients who came to our service presenting DME for 1 year was performed. Optical coherence tomography (OCT), were independently analyzed by two retinal specialist evaluators, determining the OCT tomography features of DME using the European School for Advanced Studies in Ophthalmology (ESASO) classification. An interobserver agreement analysis was performed.

Results

116 eyes of 76 patients were evaluated, being 65.8% male and 34.2% female, with a mean age of 66.3 +/- 13 years old. The Kappa analysis of intra-observer concordance in the evaluation of the different ESASO classification OCT features were: Cyst (C) (.45); Ellipsoid zone/External limitant membrane € (.4), Drill (D) (-.03); Hyperrreflective foci (H) (.47); Subretinal fluid (F) (.84); and Vitreoretinal relationship (V) (.63)

Conlusions

The agreement between observers was strong for F, moderate for V and week for the rest of OCT ESASO classification features.
