Optovue Spectral Domain OCT
Dr. Bagley becomes one of the first eye doctors in the nation to have the latest in OCT technology.
Older OCT's, while valuable, were slow and had poor resolution. It was impossible to see if the same part of the eye was being tested each visit. They were only able to test the back of the eye.
Now, with the Optovue Spectral domain OCT, we can test both the front and back of the eye, with high speed and high resolution. The testing is now registered so that we know we are rechecking the identical part of the eye each time.
OCT uses light to perform in vivo histology.
Imagine the value of a doctor being able to remove a bit of tissue, and then look at it under a high powered microscope. With OCT technology we can now look at the tissue of the eye at the magnification and near resolution of a microscope, without removing any tissue. It is quick and easy, with no discomfort, and no risk. It is 100% safe.
The picture to the left shows the angle of the eye. With this information we can determine blockage to the fluid flow of the anterior chamber.
This is essential in the diagnosis and treatment of Glaucoma.
For the diagnosis and management of Glaucoma, OCT technology allows us to look at the thickness of the Retinal Nerve Fiber Layer, or RNFL. Loss of thickness, or changes in the thickness of this layer of tissue are associated with glaucoma.
With OCT we can look at the structure of the eye and look for abnormalities or changes. These measurements are compared to a normative database, and enable us to quickly determine if a patient is healthy or not.
Our latest OCT technology now allows us to track these changes over time, measuring the exact same tissue each year, verses older technology estimating which areas are measured each year.
Thin Corneas are associated with Glaucoma. There are several technologies that can be used to measure corneal thickness. Only with the latest OCT technology can we measure the thickness of the whole cornea, and map it out for more detailed analysis.
High Speed and High Resolution OCT allows us to map out a full 3-D reconstruction of the optic nerve, macular, or other ocular structures. Older technology could not provide this level of detailed analysis.
Small Changes over time can now be tracked with precision.
Detailed mapping of both the optic nerve, and the RNFL allow for both quick interpretation and detailed analysis of the eye.
OCT analysis of the macula and retinal tissue is second to none. New technology allows for enhanced ability to diagnose and monitor treatment of a variety of conditions including:
and hundreds of other conditions.
What we can now see, compared to the days before OCT is analogous to turning on the lights in a darkened room!
Because of the high resolution of Spectral Domain OCT, we can now measure and evaluate the Ganglion Cell Complex directly. This may be the most direct way to test for Glaucoma progression. This type of testing is only now beginning to be studied.
In addition to measuring the corneal thickness and angles of the eye, we are beginning to see the possibilities of other testing on the front of the eye. Diseases such as keratoconus, keratitis, and others may be evaluated and monitored with this technology in the future. Already we can see how this technology will help with evaluating corneal surgeries such as LASIK, PRK, RK, and penetrating keratoplasties.
