Quick Reference Manual

Topcon DRI OCT Triton is an advanced optical coherence tomography (OCT) device that provides detailed cross-sectional images of the retina and anterior segment of the eye. It is used by eye care professionals to diagnose and manage a wide range of eye conditions, including glaucoma, macular degeneration, and diabetic retinopathy.

The DRI OCT Triton offers a variety of scan modes, including:

  • Macula scans: These scans provide detailed images of the macula, the central part of the retina responsible for sharp central vision. They can be used to diagnose and manage conditions such as macular degeneration and diabetic retinopathy.
