Image analysis to improve diagnosis of exfoliation

Purpose: To improve visualization of exfoliation material in standard colou r photographs by image analysis. Methods: Standard anterior segment colour photographs taken from 17 patient s with known exfoliation were subjected to film scanning with a maximum acc uracy of 3175 dpi. Results: Before image scanning, visualization of exfoliation was classified as barely visible in 10 (59%) patients and clearly visible in 7 (41%) pati ents. After the image scanning, exfoliation material became clearly visible in 13 (76%) patients and could easily be demonstrated. Conclusion: Diagnosis of exfoliation material can be improved by standard f ilm scanning.
