Carl Zeiss Cirrus 4000 HD OCT

The ZEISS Cirrus HD-OCT 4000 (Cirrus HD-OCT or Cirrus) enable examination
of the posterior and anterior of the eye at an extremely fine spatial scale,
without surgical biopsy or even any contact with the eye.
The Cirrus HD-OCT builds on and refines the retinal imaging technology
first introduced with the ZEISS Stratus OCT HD-OCT stands for
"high-definition optical coherence tomography."
