Heidelberg Retina Tomograph
HRT Glaucoma Module
A Powerful Predictor of Change
The Heidelberg Retina Tomograph (HRT) is a proven, essential tool for detecting and managing glaucoma, especially for assisting in the identification of early disease and tracking progression. The Ocular Hypertension Treatment Study (OHTS) demonstrated that optic disc analysis detected glaucoma conversion in 55% of cases, before any detectable loss of visual function. The HRT has proved to be a robust predictor of glaucoma. OHTS also concluded that the HRT recognized temporal superior defects which later developed into confirmed glaucoma in 40% of cases – looking only at baseline measurements – then confirmed the diagnosis with an average of 5 years of follow-up. Equally impressive was that 93% of all HRT cases flagged as within normal limits at baseline remained within normal limits during the same time period.
HRT Retina Module
Front Line Evaluation of Macular Health
The retinal thickness measurements of the HRT Retina Module create a complete map of the scanned area without interpolating data. Compared to the Edema Index, Retinal Thickness maps may be more useful for tracking disease changes as therapy continues. The 3-D maps are helpful for showing and explaining retinal abnormalities to the patient. Retina Thickness 3-D Map Images
