Performance of Optic Disc Drusen Diagnostic Modalities Stratified by Age and Drusen Characteristics

Enhanced Depth Imaging Optical Coherence Tomography (EDI-OCT) is emerging as the most reliable Optic Disc Drusen (ODD) diagnostic modality. However, it is unclear whether its diagnostic performance varies according to patient's age or ODD characteristics. Hence, we sought to compare the diagnostic accuracy of 4 imaging modalities-B-scan ultrasonography (US), fundus photography, fundus autofluorescence (FAF), and EDI-OCT- stratified by 1. Patient's age, 2. size and 3. depth of ODD
