Heidelberg III Retinal Tomograph (HRT)

The Heidelberg Retinal Tomograph (HRT) set the standard for analyzing 3D structural change to the retina, especially in examining the optic nerve head. This capability lead to outstanding predictive clinical results in the National Eye Institute's (NEI) Ocular Hypertension Treatment Study and the European Glaucoma Prevention Study.

At our office The Heidelberg HRT III offers different analysis modules tailored to evaluating structural changes for retinal edema, glaucoma, diabetic retinopathy, macular degeneration as well as many neurological problems such as brain tumors and Multiple sclerosis.

Retinal Thickness

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.

Reflectance Map

The reflectance image is an additional tool on the HRT which helps to reveal retinal abnormalities. The reflectance image captures differences in the surface appearance of the retina and enables interpretation of both the Edema Index and the Retinal Thickness maps.
