The Topcon Maestro 3D OCT combines anterior and posterior segment optical coherence tomography (OCT) with a fundus camera. This novel instrument not only saves a lot of space in your office with its multi-functional capabilities but also a lot of time. The Topcon Maestro is able to take all of its measurements in a completely automated way in just a few seconds. The Topcon Maestro has been a crucial instrument in our office and here we’ll share our top 5 uses of it.

1) Fundus photography

In addition to the plethora of other imaging modalities on the Topcon Maestro, it is able to capture single frame fundus photos simultaneously while scanning other images. Despite being one of the oldest forms of ophthalmic imaging, fundus photography is still an essential part of today’s clinical practice, from documenting retinal lesions to monitoring glaucomatous optic nerves. The Topcon Maestro can also compile montages of several photos taken in different retinal quadrants.

Figure 1 shows fundus photos of severe nonproliferative diabetic retinopathy.

In Figure 2, we see a fundus photo montage of posterior poles with moderate nonproliferative diabetic retinopathy.

2) Retina/macula OCT

The ability to assess disorders of the retina and macula via OCT is essential for clinical practice today. The Topcon Maestro’s ability to take a single scan OCT as well as cube raster scans of the macula enhances diagnosis and treatment for retinal pathology. All OCT images are taken simultaneously with a corresponding photograph.

Figure 3 represents macula OCT of moderate nonproliferative diabetic retinopathy with macular edema.

Figure 4 demonstrates moderate NDPR with macular edema as seen in an OCT scan with accompanying fundus photos.

3) Optic nerve OCT

Having a technique to image and assess the optic nerve is crucial for today’s eye care practitioners. OCT has revolutionized the way we diagnose and treat optic nerve pathology. This provides the clinician a simple way to assess optic nerve structure, as well as the integrity of the retinal nerve fiber (RNFL) and ganglion cell layers.

As seen in Figure 6 of the optic nerve OCT scan for primary open angle glaucoma of the right eye, the red-free filter is also a nice feature, allowing for a closer look at various disorders of the retina and optic nerve. Here, the red-free image shows a superior wedge defect which corresponds with RNFL thinning.
