Comparing Diagnostic Accuracy of EDI-OCT, B-scan, Fundus Photography, and Autofluorescence to Detect Optic Disc Drusen

The traditional gold standard imaging modality for the detection of optic disc drusen (ODD) is B-scan ultrasonography. However, newer imaging modalities such as enhanced depth imaging optical coherence tomography (EDI-OCT) can provide higher resolution images of deeper structures. A recent study reported that EDI-OCT had a sensitivity of 92% and specificity of 96% (1). We sought to compare the diagnostic accuracy of 4 imaging modalities for the detection of ODD: EDI-OCT, B- scan ultrasonography, fundus photography, and fundus auto-fluorescence (FAF)
