Abstract Details


To compare the characteristics of the choroidal pigmentary lesions using conventional colour fundus photography (CFP) and multicolour imaging (MCI).


University of California San Diego, Shiley eye institute, Jacob retina centre


The paired images of patients with CFP and MCI for choroidal masses were reviewed. The visibility of border, halo, and drusen was graded using a grading scale (0-2) and the size of the lesions was compared on both images. Further grading was also done on the individual colour channels in MCI


Thirty-three eyes of 33 patients were included. The mean size of the choroidal mass was 18.7±3.4 mm2 on CP and 14.9±3.3 mm2 on MCI (p=0.01). Lesion borders were clearly visualized by CFP in 90.9% of eyes and in 72.7% of eyes by MCI. Overall, there were no significant differences in the mean border, drusen and halo visibility scores between these two imaging modalities (p=0.12, p=0.70, p=0.35).


Multicolour imaging can provide similar information with CP on the features of choroidal mass including halo and drusen. However, total lesion area may appear smaller in this technique.
