| The aging population and rise in obesity are driving increased incidents of both age-related macular degeneration and diabetic retinopathy. The HRT Retina Module enables a fast, simple method of evaluating macular health without interpolating the data.
The Edema Index is a fast, easy method of detecting suspicious retinal areas that may not be readily apparent to the clinician even under careful contact lens examination. The HRT is designed to image retinal changes caused by minor accumulations of fluid.
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.
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. |
