Fundic imaging with the D-EYE was performed on 5 cats, 5 dogs, and 5 rabbits after pupillary dilation and fundic examination. For each patient, a multishot series and video sequence were recorded to evaluate device utility. The device was found to safely and reliably capture still images and video of the fundus in all animals. Posterior segment anatomic structures were readily viewed in sufficient detail. Video recording was more representative of ophthalmoscopic examination and enabled distinction between tapetal overexposure versus true pathologic tapetal hyperreflectivity.
Normal and pathologic anatomy was readily discerned and documented non-invasively. Potential benefits include relative low cost and portability. Limitations include a narrow field of view, compatibility with a limited number of smartphones, and somewhat common overexposure of the tapetal fundus with still images.
Although a potentially useful tool in the clinical setting, the D-Eye is not a substitute for a thorough ophthalmoscopic examination.
