    QUANTIFICATION OF INTRARETINAL HARD EXUDATES IN EYES WITH DIABETIC RETINOPATHY BY OPTICAL COHERENCE TOMOGRAPHY

    Purpose: To evaluate the reproducibility of intraretinal hard exudate (HE) quantification from spectral domain optical coherence tomography (SD-OCT) images of eyes with diabetic retinopathy (DR). Methods: Cases with diabetic macular edema were enrolled. The area of HE obtained by B-scan segmentation was compared with the area obtained by en face segmentation. Results: The mean +/- SD for the HE area was 1.78 +/- 1.37 mm2 with B-scan segmentation and 0.72 +/- 0.82 mm2 with the automated en face analysis tool; the absolute difference was 1.01 +/- 0.64 mm2. There was excellent correlation in total HE area between the ...
