D-15-d de LanthonyAbstract
The desaturated D-15 test ( D-15-d) is a more sensitive version of the Farnsworth D-15 and permits the rapid detection of axes of chromatic confusion. The high level of precision and specificity required by the Lanthony D-15-d render it a suitable screening test for colour vision anomalies in a work place. The objective of this study was to evaluate the reliability of the Lanthony D-15-d among a population of 62 subjects not previously exposed to known ophthalmotoxi agents. The rest was administered once a week for four weeks to each subject, always on the same day at the same time. No significant differences were observed between results obtained
for right and left eye testing over the four-week period. The chromatic confusion index increased significantly with age. These results confirmed the reliabilty of the Lanthony D-15-d test.
