ZEISS PLEX Elite 9000 Swept-Source OCT

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® Eliteelevates 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.

Drag the slider side-to-slide 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.

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.
