Heidelberg Retinal Tomography
Our office is now equipped with the latest technology used in the early detection and follow-up of glaucoma, the Heidelberg Retina Tomography (HRT). This machine is a Laser Ophthalmoscope which can precisely measure and analyze the shape of your optic nerve. It is a scanning Laser, not a treatment Laser, and is in no way harmful to the eye. Repeated measurements of the optic nerve with the HRT unit can pick up glaucoma damage earlier than visual field testing.
This test takes only minutes to complete and usually does not require pupil dilation. You must be able to look steadily at a small light for approximately 6-10 seconds while the photograph of your optic nerve is being taken. Each eye is measured separately. A computer compares the shape of your optic nerve to normal data and analyzes changes in your optic nerve over time.
At present, the cost of this examination is not covered by the Ministry of Health. The fee of $100.00 for imaging both eyes will be billed directly to you. You may need an examination every 6 to 12 months.
The Heidelberg Retina Tomography is an excellent addition to our diagnostic tools in glaucoma management. It will be used in combination with intraocular pressure measurement, visual field testing, and regular eye examinations to better manage your glaucoma.
