Abstract:

ABSTRACT.Purpose:

To improve visualization of exfoliation material in standard colour photographs by image analysis.

Methods:

Standard anterior segment colour photographs taken from 17 patients with known exfoliation were subjected to film scanning with a maximum accuracy 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%) patients. 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 film scanning.
