Zeiss Cirrus 500 Vs 5000

Primus 200 OCT

Brand
  • OCT machines are an essential part of the practice of any eye professional, since they can produce volumtetric data of the retina and the choroid, showing not only blood flow but also structural information.
  • OCT machine prices vary widely, going from $35,000 to over $100,000.
  • Prices drop significantly for a used or refurbished unit, starting at less than $10,000.
  • The best OCT machines in the market are offered by the brand Zeiss, specialized in ophthalmologic devices.

Some of their OCT machines are the HD-OCT Cirrus 6000, the HD-OCT Cirrus 500, the HD-OCT Cirrus 5000, the HD-OCT Cirrus 5000 with AngioPlex and the Primus 200 OCT.

  • OCTA is a new imaging method developed to produce angiographic visualizations of the retina, choroid and skin.
  • Although commercial units started being available in 2012, it is only in 2014 when the first clinical studies were published. It stands out for being non-invasive and for its practicality, specially when it comes to following up patients with vascular diseases.
  • In ophthalmology, OCT machines are capable of producing high resolution imaging and delivering volumetric information in a matter of seconds. This represents a significant contrast with dye based angiography, which in nature is more invasive and time consuming.
  • Although it remains to be seen if OCTA can replace dye based angiography in all its uses, its capabilities are improving each year thanks to frequent software updates and better hardware.
  • OCT machines can produce volumtetric data of the retina and the choroid, showing not only blood flow but also structural information.


While dye based angiography is limited to the surface of the retina, OCTA can account for depth in their angiographic visualizations. Thanks to its highly detailed imaging, OCTA can provide the exact size, site and location of neovascular lesions.

Furthermore, OCT combines angiographic visualizations with cross-sectional representations of the retina.

Final Thoughts

Thoughts on RNFL Thickness Measures

OCT is reported to be 90% accurate at diagnosing several types of CNV, and studies suggest it carries a lot of potential efficacy for diagnosing diseases including diabetic retinopathy, age-related macular degeneration and retinal vascular occlusions. Newer models like the HD-OCT Cirrus 6000 can compete —and sometimes surpass toe to toe with other methods in almost any assessment.

Scan Acquisitions

Usually, OCT involves putting dilating eye drops in the patient’s eye as preparation. The only thing that they have to do is place their head on a support and look into the lens of the device. The eye practitioner will operate the device —usually with a joystick or a mouse— and perform the necessary scans. The duration of the process depends on the OCT machine and on the disease to be diagnosed, but most of the time it only takes a few seconds. OCT machines can represent a big investment.
