Abstract: : Purpose:To obtain greater detail and number of findings from the optical coherence tomography (OCT) image, we developed an original computer software program.Methods:We used a commercially available software development environment to produce our program. The new software utilizes the tomographic and monochromatic images produced by the standard OCT program, identifying a proportional and corresponding site on the two images.Results:With this new program, the location and extent of morphological changes on the tomographic image can be pinpointed on the monochrome fundus image. By comparison, the standard pre-existing OCT program provides only the ability to generally estimate site location and measurement on the monochrome image. Our new software allows us to more readily differentiate significant findings from mere artifacts, as well as to measure the proportional lengths of two corresponding points on the tomographic and monochromatic images. The cupping / disc (C/D) rate can also be calculated with the software. The disc area is defined on the monochrome fundus image, and cupping is defined by observing the slope of the optic disc on the tomographic image, whereas previously, we had to define them using only the tomographic image.Conclusions:We believe that a location and measuring technique such as that made possible with our new software program is highly useful when interpreting findings obtained from the standard pre-existing OCT program.
