Device Technologies unveiled Topcon’s new Swept Source DRI OCT Triton at the Southern Regional Congress in February.
Heralded as the new dimension in optical coherence tomography, the Triton is the first commercially available posterior ‘Swept Source’ OCT unit with combined anterior scan capability that allows deeper penetration of ophthalmic structures.
Calling it the next generation in the evolution of OCTs, Device Technologies says that Triton’s 1050 nm longer wavelength of light allows the DRI OCT Triton to reveal posterior segment structures previously invisible to conventional forms of OCT. The scans penetrate ocular tissues such as the choroid and even the sclera, without the light source being obscured by cataracts or other media opacities like a haemorrhage.
Capturing at 100,000 A-scans per second and at 1050 nm wavelength, the signal penetration is greater through the retinal pigment epithelium (RPE). The Triton also offers full choroidal thickness mapping and coronal imagery to a digital resolution of one micron.
The wide field scanning allows automated mapping and illustration of both the macula and optic disc topography in a single scan, allowing segmentation of the retina, ganglion cell complex and the RPE, a feature that could potentially halve the number of scans the patient requires.
