Spectral Domain Optical Coherence Tomography (SD-OCT)
Moving at the speed of light!
Optical Coherence Tomography (OCT) is a non-contact medical imaging technology similar to ultrasound and MRI. With OCT, reflected light is used to produce detailed cross-sectional and 3D images of the eye.
An early version of this technology, time domain OCT (TD-OCT), uses a moving reference mirror for measuring the time it takes for light to be reflected. This relatively slow, mechanical process limits both the amount of data that can be captured as well as image quality. TD-OCT data is acquired at approximately 400 axial scans, or A-scans, per second.
The newer Spectral (or Fourier) domain OCT (SD-OCT) uses a significantly faster, non-mechanical technology. The SPECTRALIS® SD-OCT simultaneously measures multiple wavelengths of reflected light across a spectrum, hence the name spectral-domain. The SPECTRALIS system is 100 times faster than TD-OCT and acquires 40,000 A-scans per second. The increased speed and number of scans translates into higher resolution and a better chance of observing disease.
The SPECTRALIS system is much more than just a faster next generation OCT. High speed image acquisition is combined with custom TruTrack technology to actively track the eye during imaging. Tracking eye movement with simultaneous dual-beam imaging minimizes motion artifact, enables noise reduction and allows the instrument to precisely track change over time. The result is point-to-point correlation between fundus and OCT scans, greater image detail and clarity, and more confident assessment of small changes.
By integrating SD-OCT with confocal laser scanning (cSLO), the SPECTRALIS platform has advanced the role of SD-OCT in eyecare at Premier Vision in Amarillo. This combination of SPECTRALIS SD-OCT and cSLO fundus imaging reveals new details through multiple perspectives of the retina. These additional views are helping redefine diagnosis and treatment of many major eye diseases.
SPECTRALIS SD-OCT offers True Track Technology, which enables accurate and repeatable alignment of the OCT and fundus images, Heidelberg Noise Reduction for fine image detail and AutoRescan for precise follow-up scan.
Ultra Wide Field Retinal Imaging
Ultra-widefield retinal imaging supports diagnosing, analyzing, documenting and monitoring ocular pathology that may first present in the periphery of the retina, and otherwise may go undetected using traditional examination techniques and equipment.
Premier Vision in Amarillo is once again expanding the boundaries of ultra-widefield imaging. Our newest device offers multiple wavelength imaging, including options for color, red-free, and autofluorescence.
With simultaneous non-contact pole-to-periphery views of more than 80% or 200 degrees of the retina in a single capture, the device helps the doctors of Premier Vision discover more evidence of disease and guide their treatment decisions.
Specular microscopy allows our doctors to analyze the cell layer that forms the back surface of the cornea – the clear dome on the front of the eye.
Those cells are vitally important to help keep the cornea crystal clear. They are micro-pumps that regulate the amount of fluid to keep this tissue from clouding.
Sleeping in contact lenses and wearing dirty, old contact lenses are two of the biggest risk factors to cause damage to these cells. As these cells suffer damage and die, they are not replaced. If too many cells are lost, vision may be blurred or fluctuate from morning to evening.
The typical microscope most doctors use does not allow the detailed evaluation that the specular microscope allows our doctors. As a result, we are able to intervene before too much irreversible damage occurs if we see you soon enough.
The specular microscope is one more investment in our patients that Premier Vision has made to ensure that our patients’ eyes are healthy and keep our patients seeing the best that they can.
Visual Field Testing
Visual field testing remains the main diagnostic tool to provide information about a patient’s visual function, quality of vision and quality of life. Functional testing supports the doctors at Premier Vision in Amarillo in early disease detection, staging of disease or trend analysis in progressive glaucoma.
2-in-1 perimetry with Heidelberg Engineering Perimeter (HEP) offers the most appropriate test for each stage of disease. It allows you to offer the right stimulus to your patient at the appropriate stage of disease.
Fundus photography is an advanced digital retinal photograph. By taking a digital fundus photo image of the back portion of the eye (the retina), the doctors of Premier Vision in Amarillo are able to detect and monitor ocular health. The image that is produced captures a clear view of the optic nerve, blood vessels, macula and fovea.
Fundus photos can be a baseline measurement for future comparison, which is especially important in documenting and monitoring diseases such as Glaucoma, Macular Deneration, Diabetic retinopathy and many other chronic, progressive disorders.
Visually Evoked Potential (VEP) testing use a technology to objectively measure the functional responses of the entire visual pathway from the anterior segment of the eye to the visual cortex. This results in both objective and functional test results, no verbal response or “button pushing” required.
Pattern Electroretinogram (pERG) technology helps eye care specialists gain objective, functional information about the performance of the inner retinal cells of the eye, especially in the macula. This results in both objective and functional test results, no verbal response or “button pushing” required.
Ocular Surface Disease (Dry Eye) Diagnosis and Treatment
LipiView with Dynamic Meibomian Gland Imaging (DMI) and Lipiflow
Dry Eye Disease effects millions of people of all ages starting in the 20s and progressing through the 90s. The broad range of symptoms of Dry Eyes include a sandy, gritty sensation in the eyes, fluctuating vision, tearing, or a constant feeling of an eyelash stuck in the eye. In some patients, this ocular surface disease (OSD) can be painful leading to slowed reading speed, decreased work productivity, trouble focusing on the computer monitor, or difficulty seeing to drive safely. Premier Vision in Amarillo is delighted to be the first practice in Amarillo and one of the first in Texas to offer patients relief from their Dry Eye Disease with the advanced TearScience System that includes the LipiView® with DMI imaging and the Lipiflow® treatment.
Dynamic Meibomian Imaging®, a sophisticated instrument with a built-in interferometer, is the first device of its kind that captures images of your meibomian glands along your eyelids. Your doctor will be able to determine whether you have Meibomian Gland Dysfunction (MGD).
You will be able to see images of your own glands with the advanced technology of the Dynamic Meibomian Gland Imaging system (DMI). With your doctors explanation, you will have a better understanding of Meibomian Gland Disease. If your glands are plugged-up and obstructed, the natural oils cannot flow to coat your ocular surface, leading to faster evaporation of your tears. This will lead to evaporative dry eyes.
LipiView ® can also asses your blinking function by analyzing if your blinks are complete. Incomplete blinking results in a poor quality tear film which exacerbates dry eye.
LipiFlow® is designed to treat the root cause of evaporative Dye Eye Disease by unplugging the blocked meibomian glands. It is a very safe option with over 150,000 treatments performed in the US to date. Opening and clearing these blocked glands will allow them to resume their natural
production of lipids (oils) needed for a healthy tear film. A disposable activator is placed on each eyelid. These eyepieces use a patented, precisely controlled heat that is applied to the inner eyelid with pulsed pressure to unblock the meibomian glands. This thermal pulsation system not only unclogs the glands but also encourages them to resume their natural production of the lipids needed for healthy tears. Its single-use design and built-in sensors ensure a safe, sterile treatment. The process is very soothing and lasts approximately 15 minutes.
Premier Vision has the experience and technology necessary to provide treatment, consultation, and if necessary surgical referrals to achieve optimal ocular health and vision at our office in Amarillo. Schedule an appointment with your eye care provider, and we will be in touch with you shortly.
