Spectral Domain Optical Coherence Tomography (SD-OCT) is a diagnostic test that allows for the imaging and measurement of retinal thickness and is very useful in detecting retinal swelling or fluid accumulation in macular disease and the diagnosis of early glaucoma. Early diagnosis of retinal nerve fiber defects and swelling is important for the best visual outcomes. It is also useful for following the response to a treatment of retinal diseases. Neurological conditions affecting the eye, such as multiple sclerosis, can reveal itself in the earliest stages with this technology. OCT can also be used to image the anterior portion of the eye. Such imaging allows for the earliest diagnosis and treatment of sight threatening eye diseases such as glaucoma, macular degeneration and diabetic retinopathy. The level of detail and ability to see changes overtime make this an indispensible addition to your quality of care that we strive to deliver
How does it work? OCT uses rays of light to measure retinal thickness and can be performed in a few minutes. No radiation or X-rays are used in this test. The test is fast and painless and you do not need to be dilated. Results are immediately available.
Who should have OCT testing? Patients taking high risk medications, diabetics or patients with eye diseases such as glaucoma and macular degeneration should have OCT evaluations performed regularly.
Patients with family history of glaucoma or retinal disease who are not yet showing disease process may opt to have a baseline performed as a screening and to establish what your retinal thickness is.
We will evaluate your risk factors and inform you if this testing should be done.
Our Zeiss Cirrus OCT instrument is maintained in our Buchanan location. Due to the fragility and size of the equipment, patients requiring OCT of the macula will be scheduled in the Buchanan location for this test. Imaging is performed by a trained technician and no appointment with the doctor is necessary for the imaging visit. Results will be reviewed by the doctor and you will be notified of the outcome. You usually do not need to be dilated for this appointment. The appointment usually takes 20 minutes.
Most insurance companies will cover this testing if you have a medical diagnosis supporting the need for this evaluation. Please bring your insurance information to each visit.
