Purpose: To compare the quality of stereoscopic photographs of diabetic CSME eyes using two different methods of retinal photography: simultaneous stereoscopic photographs [NIDEK] and standard sequential 35 mm photographs in film [TOPCON]. Methods: The patients with CSME underwent stereo fundus photos of the macula using the Nidek 3 Dx system (NIDEK technologies, Inc., Pasadena, California) and the Topcon retinal camera (TRC-50IA, Paramus, NJ). The Nidek 3Dx camera system is a simultaneous stereocamera that produces stereoscopic images with a single flash, as opposed to the standard consecutive stereophotography requiring 2 photographs in sequence. 35 mm slide images were obtained. Three members of the ophthalmology department (2 retina specialists and 1 ophthalmologist) graded the photographs using a 3-point scale for resolution and stereoscopic image. Grading system used was: score 1 for excellent clarity and stereoscopic image; 2 for good definition of most retinal details and stereoscopic image; and 3 for definition limited and no stereoscopic image. Results: All images were stereoscopic in both groups. CSME was detected in all eyes in both groups by all 3 investigators. The grading of the quality of the stereoscopic photos was excellent (score 1) in all eyes in the Nidek group and good to excellent (scores 1-2) in the Topcon group. Conclusion: The quality of stereoscopic macular images with the Nidek 3Dx camera were graded to be superior than the standard 2 slide sequential stereo photographs using the Topcon camera. The Nidek 3Dx stereo camera may be a better tool in the recording of diabetic macular edema.
