Heidelberg HRT-3 Retinal Tomographer

The Heidelberg Retina Tomograph (HRT) is a proven, essential tool for detecting and managing glaucoma,
especially for assisting in the identification of pre-perimetric disease and tracking progression.
The Ancillary Study to 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.
