OBJECTIVE: The aim of the study was to compare the diagnostic properties of a non-mydriatic 200° ultra-widefield scanning laser ophthalmoscope (SLO) with mydriatic ETDRS 7-field fundus photography for diabetic retinopathy screening. METHODS: A consecutive series of 66 eyes from 34 patients with different levels of diabetic retinopathy (DR) were examined. Grading of DR and macular edema (ME) obtained from mydriatic ETDRS 7-field fundus photography were compared with grading obtained from Optomap Panoramic 200MA SLO images. All SLOs were performed with an undilated pupil and no additional clinical information was used for evaluation of images by two independent, masked experts. RESULTS: A total of 14 eyes from ETDRS 7-field fundus photography and 11 eyes from Optomap could not be graded by at least one grader due to poor image quality, yielding 48 eyes for comparison purposes. Of the 48 ETDRS 7-field fundus photographs, 9 (11 for grader 2) eyes had no or mild DR (ETDRS levels ≤20) and 17 (23 for grader 2) eyes had no ME. Agreement of Optomap retinopathy grading with ETDRS 7-field fundus photography was good, kappa 0.70 for grader 1 and kappa 0.66 for grader 2. There was good agreement between both techniques for ME, grader 1 kappa 0.68 and grader 2 kappa 0.74. CONCLUSIONS: Grading of DR levels from Optomap Panoramic 200MA non-mydriatic images showed a good correlation with mydriatic ETDRS 7-field fundus photography. Both techniques are of sufficient quality for a valid assessment of DR. Optomap Panoramic 200MA images cover a larger retinal area and might therefore offer additional diagnostic properties.
