HRT-II
The HRT-II is a laser scanner designed to assess your optic disc and the rest of the retina for early detection and management of glaucoma, macular degeneration and other retinal pathologies. The HRT II uses scanning laser tomography to produce 3 dimensional images, which allow precise measurements of optic nerve head parameters. This technology is purported to differentiate between normal eyes and glaucomatous eyes even before visual field defects are detected.
