Purpose: To develop a color scheme to display optical coherence tomography (OCT 3, Carl Zeiss Meditec Inc., Dublin, CA) images enhancing subtleties of macular pathologies. Methods: Raw data files of OCT 3 images were exported to an IBM compatible PC. Different color schemes were developed and tested on the images using a software program of our own design. Newly developed color schemes were compared with the conventional pseudo-color and linear grayscale and evaluated by 3 OCT experts subjectively. Results: A color scheme with blue-green-yellow gradation pattern in low to medium pixel intensity enhanced subtleties best. Spider web like connective network structures were seen in the images of macular edema cases, while the conventional color scheme and grayscale had less power to reveal these subtleties (Figure). Conclusions: An alternate color scheme may have the potential to enhance subtleties of macular pathologies that may be overlooked with the conventional color scheme or grayscale.
