Abstract
The Topcon DRI Triton is an optical coherence tomographer (OCT) with a built-in color fundus camera. It utilizes swept source technology and has a central wavelength of 1050 nm. The scanning speed is 100 kHz and the depth resolution is 8 μ. It provides high-speed, high-resolution B-scans of the anterior and posterior segments of the human eye. It also provides 3D volumetric cubes that can be viewed in cross-sectional or in an en face format. Thickness maps are automatically generated for various retinal layers including: (1) full retinal thickness; (2) retinal nerve fiber layer (RNFL); (3) ganglion cell layer (GCL) plus the inner-plexiform layer (IPL); (4) RNFL plus GCL plus IPL; and (5) choroid layer. Due to the rapid speed of scanning, large areas of the retina can be imaged in a single scan including 3D scans covering areas as large as 12 × 9 mm, which includes both the macula and optic disc regions.
