Heidelberg Retinal Tomograph
The Heidelberg Retina Tomograph is a system that combines a laser scanning camera and specialized software that evaluates the optic nerve. The HRT may diagnose glaucoma years before symptoms become apparent to the patient. The HRT gives measurements of size, depth and shape of the optic nerve and is especially useful at detecting small changes over time.
The HRT exam takes just a few moments; it is a painless, non-invasive test and dilation of the eye is usually not necessary. The HRT is and accurate way to follow your progress and we may order repeat exams periodically to check your progress.
Remember that the key to controlling glaucoma is catching it early. The best way to prevent vision loss form glaucoma is to know your risk factors and to have eye examinations at appropriate intervals.
