ADVANCED GLAUCOMA DETECTION AND TREATMENT
Over 3 million Americans have glaucoma but only half of those know they have it. Approximately 120,000 are blind from glaucoma, accounting for 9% to 12% of all cases of blindness in the U.S. These facts make glaucoma the second leading cause of blindness in the U.S. and the first leading cause of preventable blindness.
The optic nerve is the structure which takes the visual information from the eye to be interpreted by the brain. If the optic nerve is not functioning properly, the visual information will not reach the brain. Glaucoma is a disease that results in the death of nerve cells within the optic nerve. As the cells die, there is a large crater-like center to the optic nerve.
The optic nerve as it appears in glaucoma.
Glaucoma is defined as damage to the optic nerve (neuropathy). This damage is most often caused by elevated pressure in the eye. If the intraocular pressure (IOP) is elevated above 21 mmHg (normal pressure within the eye is between 10 and 21mm Hg), diagnosis is more evident. Continued elevated pressure or a weak optic nerve can result in a damaged optic nerve. This loss of healthy optic nerve tissue is irreversible, so it is imperative to treat glaucoma as early as possible. Initial changes to the optic nerve can be difficult to ascertain but with the help of the Heidelberg Retinal Tomographer (HRT 3) or the Ocular Coherence Tomographer (OCT) these changes can be found sooner rather than later.
The HRT system is noninvasive and in most cases does not require pupil dilation
The best chance of saving vision when it comes to the disease of glaucoma is to diagnose it as soon as possible and treat it effectively. Roholt Vision is proud to offer both retinal tomography and optical coherence tomography for the earliest possible detection of glaucomatous changes to the optic nerve. These tests can allow for treatment to be initiated early in the course of the disease, in time to save precious sight.
In retinal tomography, in a matter of minutes pictures are captured producing 3-D images comprised of over 28.3 million data points.
The image of the optic nerve and the analysis of the nerve is determined following section by section analysis of the optic nerve by the HRT 3
The best use of the HRT 3 is to monitor the optic nerve over time and to allow the doctor to adjust the individualized treatment plan accordingly
Other testing performed at Roholt Vision Institute that is critical to diagnosing and treating glaucoma includes visual field testing, corneal thickness measurements, gonioscopy and multiple devices to measure the pressure in the eye. Dedication to the best technology available helps to ensure the best care possible for the patients of Roholt Vision Institute. Eye drops, laser treatments and ocular surgeries can all be incorporated into the individualized glaucoma treatment plans for each patient.
