Purpose: To determine the relationship of drusen size as determined by spectral-domain optical coherence tomography (SD-OCT) with that measured on registered color fundus photography (CFP) images and to derive an OCT-based classification system that was comparable with that determined by CFP. Methods: Custom software was developed to register CFP images to the scanning laser ophthalmoscopy fundus images obtained simultaneously with the corresponding SD-OCT images, so that individual drusen observed on CFP could be matched with those seen on SD-OCT. Single druse size (diameter, area, volume, and height) on CFP and SD-OCT images from a phase two clinical trial was determined with the Duke OCT Retinal Analysis Program. Results: The sizes of 213 individual drusen were measured on CFP and SD-OCT. The drusen diameter measured on CFP was significantly correlated with those determined on SD-OCT (R: 0.879, P < 0.001). Based on the corresponding formula: drusen diameter on SD-OCT = 0.77 x (drusen diameter on CFP) + 50.67 mu m, large drusen defined as >= 125 mu m on CFP had a diameter >= 145 mu m on OCT, medium drusen defined as 63 mu m to 124 mu m on CFP had diameters 100 mu m to 144 mu m on OCT, and small drusen defined as mu m on CFP had diameters mu m on OCT. Conclusion: With our registration software and imaging processing algorithms, we were able to correlate individual druse sizes measured on CFP with those determined on SD-OCT. These data can be used to develop an SD-OCT-based grading scale, analogous to the CFP Age-Related Eye Disease Study drusen scale that may be useful in the clinic and in clinical trials.
