Single plattform Heidelberg

The Optos can deliver UWF, high-definition color photos and red-free images and FA. This new module requires an interchangeable noncontact lens that attaches to the camera head of both the Spectralis/Heidelberg Retina Angiograph to provide evenly illuminated and undistorted, high-contrast confocal laser scanning microscope images, even in the periphery. Compared to the 200º of view with the Optos system, the Heidelberg platform provides a single nonsteered photo and can image approximately 102º of view.Jessica Lee, MD, is a retina fellow at the New York Eye and Ear Infirmary of Mount Sinai (NYEEMS). Rosen, MD, is vice chair, surgeon director, and director of ophthalmology research at NYEEMS. While both devices provide UWF imaging of the retina, the areas of the retina imaged are considerably different.Neither author reports any financial interests in products mentioned in this article. The Optos, because it can image 200º of view in one single shot, captures a significantly greater view of total area of the retina, with better visualization of the far temporal and nasal aspect of the retina compared to the Heidelberg platform.

Additionally, neovascularization of the peripheral retina in diseases such as proliferative diabetic retinopathy, retinopathy of prematurity, sickle-cell retinopathy, and familial exudative vitreoretinopathy can be a challenging entity to detect and treat.

Ultrawidefield fluorescein angiography is now widely available with a noncontact camera module on the Optos Optomap (Marlborough, MA) and the Heidelberg Spectralis (Heidelberg Engineering, Carlsbad, CA).

In primary gaze, the total retinal surface imaged on a single shot is greater with the Optos Optomap compared with the Heidelberg. Wessel MM, Aaker GD, Parlitsis G, Cho M, D’Amico DJ, Kiss S.
