Choosing the right OCT for glaucoma comes down to one thing: reliable, repeatable measurement of the optic nerve and retinal nerve fiber layer (RNFL).
Modern OCT systems provide detailed imaging, but not all are equally suited for glaucoma management. The best systems offer:
Best overall for glaucoma management
Widely considered one of the most reliable OCT systems for glaucoma
Best for advanced imaging and deeper structures
Strong option for specialists and referral centers
Best for screening and high-volume clinics
Great for efficiency, less focused on advanced progression tracking
| Feature | Cirrus | Triton | Maestro |
|---|---|---|---|
| RNFL Analysis | Advanced | Strong | Basic |
| Progression Tracking | Industry-leading | Moderate | Limited |
| Imaging Depth | Standard | Deep | Standard |
| Automation | Moderate | Moderate | High |
| Best For | Glaucoma management | Advanced diagnostics | Screening |
The ZEISS Cirrus OCT has become a standard in glaucoma due to:
For many clinics, glaucoma management is built around Cirrus data
Consistent measurement of nerve fiber thickness is critical for diagnosis.
The ability to monitor changes over time is essential for treatment decisions.
Systems must produce repeatable results across multiple visits and operators.
High-volume clinics may prioritize automation, while specialists prioritize detail.
What is the best OCT for glaucoma?
The ZEISS Cirrus OCT is widely considered one of the best systems for glaucoma due to its RNFL analysis and progression tracking capabilities.
Is swept-source OCT better for glaucoma?
Swept-source OCT offers deeper imaging, but spectral-domain systems like Cirrus remain the standard for glaucoma monitoring.
What does OCT measure in glaucoma?
OCT measures the retinal nerve fiber layer (RNFL) and optic nerve structure to detect and monitor damage.
Is OCT necessary for glaucoma diagnosis?
OCT is a key tool for early detection and ongoing monitoring of glaucoma progression.
