Heidelberg Retinal Tomography 3
The Heidelberg Retina Tomograph 3 (HRT 3) is a laser scanning system for imaging of the anterior and posterior segments of the eye. It comprises three modules which can be used independently or combined with each other. The major routine clinical application is analysis of the optic nerve head structure for glaucoma diagnosis.
Diabetic retinopathy is the leading cause of visual impairment and blindness in the western adult population. The Retina Module automatically locates and quantifies edema. Physicians appreciate this quick and noninvasive method to assess diabetic macular edema, central serous retinopathy, cystoid macular edema, occlusive diseases and macular holes. The Retina Module is the only means to precisely quantify change of retinal edema over time.
The retinal thickness measurements of the HRT Retina Module create a complete map of the scanned area without interpolating data. Retinal Thickness maps may be useful for tracking disease changes as therapy continues. The 3-D maps are helpful for showing and explaining retinal abnormalities to the patient.
Worldwide, more than 5.000 HRTs support physicians and optometrists in diagnosis and follow-up. Their experience over time has confirmed the high diagnostic value of HRT examinations, based on highly reproducible measurements. Both 2- and 3-dimensional images are acquired with high resolution and without data interpolation. Built-in quality controls enable the user to evaluate image quality during and after the acquisition. The HRT is a tried-and-tested, versatile technology you can rely on.
