ZEISS PLEX Elite 9000
Swept-Source OCT Angiography
Uncovering the Undiscovered
PLEX® Elite 9000 from ZEISS is a transformational OCT imaging technology that invites retina and glaucoma researchers into a new world of structural and microvascular clarity of the anatomy.
The First Dual-Speed Swept Source OCT
Faster, deeper, and with higher resolution, the new dual-speed PLEX® Elite 90001 elevates ophthalmic imaging and clinical research to a new level. With this technology, clinicians can support longitudinal studies while expanding the scope of their research to investigate the clinical benefits of scans acquired at 200kHz scan speed.
Explore Deeper Meanings
ZEISS PLEX Elite 9000 Swept-Source OCT allows clinical researchers the potential to see deeper, wider and in more detail from the vitreous to the sclera in the posterior segment.
- Study early mechanisms of micro- and neovascularization of the posterior segment from vitreous to sclera.
- Explore the progression of retinal and choroidal pathology, such as CNV
- Evaluate the mechanism of retina and choroid response to a therapy.
A Case of Proliferative Diabetic Retinopathy
This is a case of a young diabetic patient with severe proliferative diabetic retinopathy in both eyes. The new montage scan acquisition feature of the PLEX Elite 9000 is able to capture ultra-wide OCT angiography images that, in this case, helped the clinician clearly visualize the significant increase in the proliferation of new vessels in both eyes.
Drag the slider side-to-side to track disease progression in this DR patient over just four months. Slide to the right to see the patient’s first image. Slide to the left to see the second image, four months later.2
Drive the Discovery.
Join the Advanced Innovation and Research Network.
Discovery starts with desire—the desire and drive to go where others have only imagined, to pave a path for those who will follow. At ZEISS, we're driving the discovery by investing in people, partnerships, and the emerging technologies that will share and define the future of patient care. With an entire global community of like-minded pioneers sharing our desire for discovery, our collaboration will continue to provide inspiration for years to come.
Where collaboration thrives, innovation emerges.
