Digital Retinal Imaging & OCT Scans
At Azman Eye Care Specialists we use advanced digital imaging technology to aid in the assessment of your eyes. Like most diseases, early detection is key to a good prognosis and eye diseases are no different if detected early then most can be treated to prevent loss or slow the loss of vision. Images are stored electronically and electronically linked to your patient record. This gives us measurable and comparable data to monitor and gauge the effectiveness of treatment. Most eye conditions, such as glaucoma, diabetic retinopathy, and macular degeneration are diagnosed by detecting changes over time.
Digital Retinal Imaging
Digital Retinal Imaging allows your eye doctor to evaluate the health of the back of your eye, the retina. It is critical to confirm the health of the retina, optic nerve, and other retinal structures. The digital camera snaps a high-resolution digital picture of your retina. This picture clearly shows the health of your eyes and is used as a baseline to track any changes in your eyes during future eye examinations.
Optical Coherence Tomography (OCT)
An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is the latest advancement in imaging technology. Similar to ultrasound, this diagnostic technique employs light rather than sound waves to achieve higher resolution pictures of the structural layers of the back of the eye.
A scanning laser used to analyze the layers of the retina and optic nerve for any signs of eye disease, similar to a CT scan of the eye. It works using the light without radiation and is essential for early diagnosis of glaucoma, macular degeneration, and diabetic retinal disease.
With an OCT scan, doctors are provided with color-coded, cross-sectional images of the retina. These detailed images are revolutionizing early detection and treatment of eye conditions such as wet and dry age-related macular degeneration, glaucoma, retinal detachment, and diabetic retinopathy.
ZEISS Visante OCT Anterior Segment
The Zeiss Visante OCT provides high-resolution corneal images and documentation for the anterior segment specialist to support the evaluation of ocular health. Rapid acquisition during the pachymetry scan ensures an accurate and repeatable pachymetry map result for application in refractive and glaucoma care. In addition to providing a full-thickness pachymetry map prior to laser surgery, the Zeiss Visante OCT is the first non-contact device to image,
In addition to providing a full-thickness pachymetry map prior to laser surgery, the Zeiss Visante OCT is the first non-contact device to image, measure and document both corneal flap thickness and residual stromal thickness immediately following LASIK surgery.
OPTOVUE iVue OCT
Optical Coherence Tomography, or OCT, has changed the way eye care professionals analyze the retina, optic disc, and anterior segment structures.
The iVue OCT System is a powerful clinical tool that transforms the way you assess the retina, optic disc and the cornea. Quantify the thickness of the retina, nerve fiber layer, ganglion cell complex and the cornea. Track change and predict trends in RNFL and GCC thickness and precisely measure angles to aid in disease diagnosis. The Optovue iVue OCT includes Glaucoma, Retina and Anterior Segment OCT, scans at 26,000 A-scans per second and 5 micro resolution. Most importantly, the iVue performs the following tests:
- Glaucoma: RNFL, ONH, 3D & GCC Retina: 6 mm thickness maps, 3D and cross line scans
- Anterior Segment: angle measurement, pachymetry mapping, tear film analysis, contact lens analysis
NIDEK OPDScan Topographer
The 3-D Wave is a next-generation instrument that combines wavefront analysis, internal lenticular analysis (OPD mapping: lenticular, vitreous and retina), topography analysis, photopic and mesopic pupil size, standard autorefraction and keratometry analysis.
Zeiss Atlas Topographer
The Zeiss Atlas 9000 Corneal Topography System is a diagnostic instrument that measures the curvature of the cornea and produces topographical images. The Zeiss Atlas 9000 supports many important optometric applications, including contact lens fitting, pathology detection and management.
Corneal conditions such as asymmetrical astigmatism, a decentered apex, contact lens warpage, and irregular, peripheral and central astigmatism can dramatically affect the way a contact lens behaves on the eye. The Zeiss Atlas 9000 MasterFit II software allows customized fitting of GP lenses according to the doctor’s fitting preferences.
OCULUS Keratograph 5M is a cutting-edge piece of technology known as a corneal topographer. With its built-in real keratometer and a color camera optimized for external imaging, the Keratograph 5M produces incredible images of the unique contours of your eye, that are both extremely informative to your doctor, and easy to explain to you, the patient. Unique features include examining the meibomian glands, non-invasive tear film break-up time and the tear meniscus height measurement and evaluating the lipid layer. All of these features make the Keratograph 5M very useful in the detection and evaluation of dry eye symptoms. Patients really like the live video image that it provides of the eye.
A fundus, or retinal camera, is a specialized microscope with an attached camera designed to photograph the central retina, optic disc and macula.
The resulting photograph is a high resolution magnified image which can help to assess for eye conditions including glaucoma, diabetic retinopathy, macular degeneration, optic nerve disease, and many others. This picture also gives us a baseline to compare the state of your eye health in the future.
Konan Specular Microscope
At Azman Eye Care Specialists we use the Konan Specular Microscope to view the bottom layer of the cornea which is a critically important layer for the health and well being of the entire cornea.
Managing the care of our contact lens patients is very important. Often we can avoid more serious complications of contact lens wear by understanding the condition of the cornea better. In early stages simply adjusting the wearing time or changing to a different contact lens material avoids future complications.
We treat our senior citizen patients with the latest technology. The Konan Specular Microscope lets us observe diminishing cell count. We then can monitor and treat the aging cornea much more effectively.
Visual Field Testing
A visual field test measures the range of your peripheral or “side” vision to assess whether you have any blind spots (scotomas), peripheral vision loss or visual field abnormalities. It is a straightforward and painless test that does not involve eye drops but does involve the patient’s ability to understand and follow instructions.An initial visual field screening can be carried out by the optometrist by asking you to keep your gaze fixed on a central object, covering one eye and having you describe what you see at the periphery of your field of view.
Huvitz Wavefront Aberrometer
Aberrometry measures the way a wavefront of light passes through the cornea and the crystalline lens, which are the refractive (light focusing) components of the eye. Distortions that occur as light travels through the eye are called aberrations, representing specific vision errors. Wavefront technology, or aberrometry, diagnoses both lower- and higher-order vision errors represented by the way the eye refracts or focuses light.
