Assessment of color disc photograph (C-DP) is affected by image quality, which decreases the ability to detect glaucoma. High-dynamic-range (HDR) imaging provides a greater range of luminosity. Therefore, the objective of this study was to evaluate the capability of ophthalmology residents to detect glaucoma using HDR-concept disc photography (HDR-DP) compared to C-DP. <jats:italic>Design<\/jats:italic>. Cross-sectional study. <jats:italic>Methods<\/jats:italic>. Twenty subjects were classified by 3 glaucoma specialists as either glaucoma, glaucoma suspect, or control. All C-DPs were converted to HDR-DPs and randomly presented and assessed by 10 first-year ophthalmology residents. Sensitivity and specificity of glaucoma detection were compared. <jats:italic>Results<\/jats:italic>. The mean\u2009\u00b1\u2009SD of averaged retinal nerve fiber layer (RNFL) thickness was 74.0\u2009\u00b1\u20096.1\u2009<jats:italic>\u03bc<\/jats:italic>m, 100.2\u2009\u00b1\u20099.6\u2009<jats:italic>\u03bc<\/jats:italic>m, and 105.8\u2009\u00b1\u200917.2\u2009<jats:italic>\u03bc<\/jats:italic>m for glaucoma, glaucoma suspect, and controls, respectively. The diagnostic sensitivity of HDR-DP was higher than that of C-DP (87% versus 68%, mean difference: 19.0, 95% CI: 4.91 to 33.1; <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.014<\/mml:mn><\/mml:math>). Regarding diagnostic specificity, HDR-DP and C-DP yielded 46% and 75% (mean difference: 29.0, 95% CI: 13.4 to 44.6; <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.002<\/mml:mn><\/mml:math>). <jats:italic>Conclusions<\/jats:italic>. HDR-DP statistically increased diagnostic sensitivity but not specificity. HDR-DP may be a screening tool for nonexpert
