Abstract Details

Purpose:

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

Setting:

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

Methods:

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

Results:

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).

Conclusions:

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.
