3 Although non-mydriatic cameras provide partially reduced image quality and a reduced field of view compared to conventional cameras, the former have advantages in common circumstances (eg, for screening or emergency purposes). 2 Today, state-of-the-art digital and complex imaging systems (cameras and scanners) allow detailed imaging of retinal structures without dilating patients’ pupils. 1 In the following decades, increased light sensitivity, optimized optics, new illumination sources and digital techniques led to a continuous increase in the image quality. In 1887, Lucien Howe described an experimental approach for fundus imaging in his publication “Photography of the Interior of the Eye”. Keywords: imaging, non-mydriatic, handheld camera, learning curve For screening scenarios or telemedicine, it must be determined whether image quality or mobility is more important. The greater mobility of Camera 2 was associated with lower image quality. No remarkable learning effects could be demonstrated.Ĭonclusions: Both camera systems are useful for fundus imaging. Both systems achieved better quality grades for macular images than for disc-centered images. Quality grade comparisons showed significantly better grades for Camera 1. Results: In total, 211 people were enrolled. The images were graded separately by two experienced and “blinded” ophthalmologists following a defined protocol. In order to evaluate possible learning effects, we selected an examiner with no prior training in the use of these systems. Camera 1 (DRS ®) was a stand-alone system, while Camera 2 (Smartscope ® PRO) was a mobile system. Methods: The imaging procedures followed standard protocol and were all performed by the same investigator. The secondary outcomes were learning effects and quality grade-influencing factors. We compare the usefulness of two non-mydriatic camera systems (ie, a handheld versus a stand-alone device) for fundus imaging. These so-called non-mydriatic cameras have advantages in common circumstances (eg, for screening or emergency purposes) but present limitations in terms of image quality and field of view. Purpose: Nowadays, complex digital imaging systems allow detailed retinal imaging without dilating patients’ pupils. We were able to cut the costs to half of the previous sales case due to smart material selections without compromising the durability and brand.Mariya Gosheva, 1 Christian Klameth, 1 Lars Norrenberg, 2 Lucien Clin, 3 Johannes Dietter, 4 Wadood Haq, 4 Iliya V Ivanov, 4–6 Focke Ziemssen, 1 Martin A Leitritz 7ġUniversity Eye Hospital, Centre for Ophthalmology, Tuebingen, 2Department of Obstetrics and Gynecology, Klinikum am Steinenberg, District Hospital Reutlingen, Reutlingen, 3School of Informatics, Reutlingen University, 4Division of Experimental Ophthalmology, Centre for Ophthalmology, Institute for Ophthalmic Research, 5Vision Rehabilitation Research Unit, Centre for Ophthalmology, University Eye Hospital, Eberhard Karls, 6ZEISS Vision Science Lab, Institute for Ophthalmic Research, Centre for Ophthalmology, University of Tuebingen, 7Section for Experimental Ophthalmic Surgery and Refractive Surgery, University Eye Hospital, Centre for Ophthalmology, Tuebingen, Germany Straps, zipper and top surface are also branded.Ĭost was one of the major driving forces when this project was started. Case is easy to carry with you due to compact size and shoulder strap. Excellent drop test results prove that material choices were correct ones.īrochures and other documents have their own place and there are bands to hold the smaller parts. We have also put special attention to outer surface of the case which is now scratch and dent free. No organic materials were used to avoid mold and moisture inside the sales case. In order to offer a premium look we dropped plastic bags and chose the dust free inner material that is perfect for lenses and screen. All materials, colors and components have been chosen to match company's and product family's identity that also have an impact on the brand value and image of the company. After receiving feedback on Smartscope PRO carrying case, we have designed a completely new case for the latest Optomed Aurora fundus camera.
