Zeiss Cirrus 4000 HD OCT: Advanced Eye Imaging Technology

The Zeiss Cirrus 4000 HD OCT is a cutting-edge device enabling detailed examination of the posterior and anterior segments of the eye with extreme precision. This non-contact imaging solution eliminates the need for surgical biopsy while providing high-definition results.

Revolutionary HD-OCT Technology

This innovative device leverages spectral domain optical coherence tomography for unparalleled imaging performance:

• 70x Faster Imaging: Acquires data at 27,000 A-scans per second, compared to 400 A-scans with earlier technology.
• Enhanced Resolution: Offers 5 μm axial resolution, significantly better than the ~10 μm of first-generation OCT systems.
• Three-Dimensional Imaging: Captures whole cubes of OCT image data, enabling multi-plane visualization for comprehensive analysis.

Zeiss Cirrus 4000 HD OCT Key Features and Capabilities

Intended Use

This advanced system is designed for:

• In-vivo viewing and imaging of ocular structures, both anterior and posterior.
• Axial cross-sectional and three-dimensional imaging.
• Diagnostic evaluations for conditions such as macular holes, diabetic retinopathy, glaucoma, and age-related macular degeneration.

Indications for Use

This high-resolution imaging device offers:

• Measurement and imaging of the retina, retinal nerve fiber layer (RNFL), ganglion cells, macula, and optic nerve head.
• Access to normative databases for comparing patient data to normal subjects.
• Diagnostic insights to detect and manage ocular diseases effectively.

Essential Performance

The primary function of this device is to deliver accurate measurements of ocular structures with precision and consistency, supporting ophthalmologists in achieving reliable diagnoses.

Patient Population

The system is suitable for adult patients requiring diagnostic eye evaluations, including individuals with:

• Low visual acuity or fixation issues.
• Postural challenges or wheelchair dependence.
• Physical disabilities, as long as they can position their face in the chin and forehead rest.
