<p><b><i>Purpose:</i></b> To compare conventional 30° spectral domain
optical coherence tomography (SD-OCT) with 55° wide-field SD-OCT for the
assessment of diabetic macular edema (DME). <b><i>Methods:</i></b> This
study included 50 DME patients. Both 55° and 30° SD-OCT was conducted.
Two readers evaluated scans according to a standardized grading
protocol. Intergrader agreement as well as agreement between 30° and 55°
SD-OCT were assessed. <b><i>Results:</i></b> Intergrader agreement (κ)
was strong and ranged from 0.79 to 1.0. Perfect interdevice agreement (κ
= 1.0) was found for the detection of intra- and subretinal fluid.
Excellent agreement (κ ≥ 0.9) was found for the presence of epiretinal
membrane (κ = 0.92) and cotton-wool spots (κ = 0.92). A strong agreement
was found for the presence of hard exudates (κ = 0.89) and
microaneurysms (κ = 0.81). A moderate correlation was found for
ellipsoid zone integrity (κ = 0.69) and configuration of the
vitreomacular interface (VMI) (κ = 0.69). A weak agreement was found for
retinal pigment epithelium atrophy (κ = 0.51) and external limiting
membrane integrity (κ = 0.35). <b><i>Conclusion:</i></b> Wide-field OCT
imaging may be beneficial for evaluating DME, particularly for assessing
the VMI and the integrity of hyperreflective bands.</p>
