Heidelberg Retinal Tomograph 2 (HRT 2) is a sophisticated imaging system designed to evaluate the optic nerve head and peripapillary retina. It employs confocal scanning laser tomography technology to produce detailed three-dimensional topographic images of the optic disc, enabling precise measurement of its shape, depth, and contour. This allows clinicians to detect subtle structural changes associated with glaucoma and other optic neuropathies at an early stage.
HRT 2 generates quantitative parameters such as rim area, cup shape, and retinal nerve fiber layer thickness, which are crucial for diagnosing and tracking the progression of glaucoma. It also includes a normative database for comparison, helping to distinguish healthy optic nerves from those affected by disease. The device is non-invasive, quick to perform, and provides reproducible results, making it a valuable tool in routine ophthalmic practice for glaucoma screening, diagnosis, and monitoring treatment efficacy.
