Mastering Optical Coherence Tomography with the 3D OCT-1 Maestro
Optical coherence tomography (OCT) is a key diagnostic tool, enabling eye care practitioners to identify and monitor a number of diseases. A non-invasive diagnostic technique that provides cross-sectional images of the retinal microstructure and subretinal space, OCT enables the pathology of many eye conditions to be identi ed and tracked. Perhaps one of the major bene ts of OCT is that it can differentiate between wet and dry age-related macular degeneration (AMD). Since 2005, it has also become possible to use OCT to visualize the anterior segment including the anterior chamber angle (ACA), iris and anterior lens, enabling diagnosis of keratoconus and glaucoma.
Color fundus photography also plays an important role in the monitoring of eye heath and provides information on the functioning of the retina by allowing visualization of the retinal vasculature, macula, the optic disc and the posterior pole. Like OCT, color fundus photography is non-invasive and is invaluable in the diagnosis of numerous ocular disorders.
Meet the Maestro
The Topcon 3D OCT-1 Maestro is the latest instrument from Topcon to combine spectral domain (SD) OCT with color fundus photography. Specically, the 3D OCT-1 Maestro with a scanning speed of 50,000 A Scans/second automatically scans both eyes and simultaneously produces an OCT scan and a color fundus, thus helping the operator to quickly locate the exact position of the OCT scan and obtain additional information for diagnosis. Moreover, the auto alignment, the auto focus and auto shoot ensure that the whole process is done fast and correctly – with only the touch of a button.
Key Features of the Maestro OCT
- Compact and space saving design
- Fully automated operation: alignment, focus, capture, measurement and report generation
- 50,000 A-scans per second
- 12mm x 9mm wide eld OCT scan of optic nerve and macula
- Non-mydriatic color fundus image, including panoramic fundus and external ocular imaging
- Rich analysis and report functions
- Network, DICOM connectivity and MWL
We have 4 OCTs in our clinic, but based on my experience, we will de nitely need to add the Maestro.Pinakin Davey, OD, PhDThe instrument performs many different types of OCT scans as well as color fundus photography, panorama color fundus photography and external ocular photos. Scan settings are customized to the users preferences during installation and then the nalized settings are saved as “scan icons” that the technical staff accesses with a single touch during the capture process.
One scan pattern that is noteworthy is the 12 mm x 9 mm OCT wide eld scan allowing automated, rapid measurement and topography of the optic nerve and the macula in one scan. This wide eld scan provides a comprehensive assessment of the patient’s macula and optic disc including:

• Thickness maps of Total Retina, RNFL, GCL + IPL and GCL + IPL + RNFL
• TSNIT RNFL Thickness Grid compared to Reference Database
• RNFL Sector grids compared to Reference Database
• Various Optic Disc parameters compared to Reference Database
• ETDRS grids compared to Reference Database
• Macula 6 sector grid map compared to Reference Database
The 3D OCT-1 Maestro can be operated from various positions using a rotable 10 inch touch screen, which improves the interaction with patients dramatically. It can be operated in a classic position, or the operator can be next to the patient. In both situations, the operator can be sitting or standing. The compact design and small footprint of the 3D OCT-1 Maestro also helps to save valuable space.
