Abstract

As digital photography is being increasingly used in clinical medicine, we devised a software program for `on screen' image analysis, which allows distance, angle, and area to be measured. In this study, 30 photos were evaluated by 10 observers, so 3000 observations were used to test the reproducibility of the measurements. The results showed excellent reproducibility within observer, between observers, and between photographs. The coefficient of variation (CV) ranged from 0 to 1.3% for distance, from 0.6 to 2.3% for angle, and from 1.5 to 7.7% for area. The system could be particularly useful for assessing patients with cleft lip and palate.
