Background.
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.
Design.
Cross-sectional study.
Methods.
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.
Results.
The mean ± SD of averaged retinal nerve fiber layer (RNFL) thickness was 74.0 ± 6.1 μm, 100.2 ± 9.6 μm, and 105.8 ± 17.2 μm 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; p=0.014).
Regarding diagnostic specificity, HDR-DP and C-DP yielded 46% and 75% (mean difference: 29.0, 95% CI: 13.4 to 44.6; p=0.002).
Conclusions.
HDR-DP statistically increased diagnostic sensitivity but not specificity.
HDR-DP may be a screening tool for nonexpert ophthalmologists.
