Corneal Mapping

Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye’s refractive power, its topography is of critical importance in determining the quality of vision.

The three-dimensional map is therefore a valuable aid to the examining ophthalmologist or optometrist and can assist in the diagnosis and treatment of a number of conditions; in planning refractive surgery such as LASIK and evaluation of its results; or in assessing the fit of contact lenses. A development of keratoscopy, corneal topography extends the measurement range from the four points a few millimeters apart that is offered by keratometry to a grid of thousands of points covering the entire cornea. The procedure is carried out in seconds and is completely painless.

Digital Retinal Imaging & OCT Scans

Our Dallas eye care experts use cutting-edge digital imaging technology to assess your eyes. Many eye diseases, if detected at an early stage, can be treated successfully without total loss of vision. Your retinal Images will be stored electronically. This gives the eye doctor a permanent record of the condition and state of your retina.

This is very important in assisting our optometrist in Dallas, Georgia to detect and measure any changes to your retina each time you get your eyes examined, as many eye conditions, such as glaucoma, diabetic retinopathy and macular degeneration are diagnosed by detecting changes over time.

The advantages of digital imaging include:

  • Quick, safe, non-invasive and painless
  • Provides detailed images of your retina and sub-surface of your eyes
  • Provides instant, direct imaging of the form and structure of eye tissue
  • Image resolution is extremely high quality
  • Uses eye-safe near-infra-red light
  • No patient prep required

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 in 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 an CT scan of the eye. It works using 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.

An OCT scan is a noninvasive, painless test. It is performed in about 10 minutes right in our office. Feel free to contact our office to inquire about an OCT at your next appointment.

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. Our office carries the Haag-Streit visual field test.

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. For a more comprehensive assessment, special equipment might be used to test your visual field. In one such test, you place your chin on a chin rest and look ahead. Lights are flashed on, and you have to press a button whenever you see the light. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check you are concentrating. Each eye is tested separately and the entire test takes 15-45 minutes. These machines can create a computerized map out your visual field to identify if and where you have any deficiencies.

Medmont E300 Corneal Topographer

We are proud to use the Medmont E300 Corneal Topographer, a computerized video-keratometer, in our office.

The Medmont E300 offers extreme accuracy for the mapping of a patient’s cornea. It has a standard deviation of error of less than 2 microns. To put that into perspective, the average human hair is 75 microns.

It is also the only Placido Ring Topographer on the market that can map the cornea from Limbus to Limbus. This is a huge advantage when fitting GP or Scleral lenses.

Zeiss Fundus Camera

A fundus camera is a specialized microscope that has a camera attached. It photographs the retina and translates it into images that our brains can process. The patient sits in a chair with his chin resting on a chin pad, and the camera is aligned. As the shutter is released, the fundus image is taken. These images can be used to diagnose eye diseases.

Fundus photography can be used with colored filters or with specialized dyes.

Heidelberg Spectralis OCT

The SPECTRALIS® expandable diagnostic imaging platform can be upgraded with the OCT Angiography Module to perform non-invasive, layer-by-layer examinations of flow in the vascular networks of the retina and choroid. Combined with structural OCT and fluorescence angiography, the OCT Angiography Module enables a more comprehensive understanding of vascular abnormalities.

TelScreen EyeRes Anterior Segment Camera

The TelScreen EyeRes Anterior Segment Camera is a cutting-edge technology for taking high-resolution pictures and videos of the front of the eye and eyelids. It uses a programmable sensor to capture precise images that allow in early detection of many sight-threatening eye conditions.

The Optomap® Retinal ExamThe Optomap® Retinal Exam

The Optomap® Retinal Exam gives our doctors a larger view (200 degrees) of the back of the eye – your retina – than conventional eye examination equipment. The images can be taken without dilating your pupils – a very common procedure which is uncomfortable and inconvenient for many people.

Each Optomap image is as individual as fingerprints or DNA and can provide eye care professionals with a view of your health very quickly and comfortably. The Optomap image is captured in less than one second and is immediately available for you and your doctor to review. Using the Internet, the image can be sent anywhere in the world for a specialist to review, if necessary.

The Optomap Retinal Exam offers many advantages including:

Provides an ultra-widefield view of the retinaComfortable and quick image captureNon-invasiveHelps you understand your eye healthProvides permanent records for future comparisonThe Optomap technology does not require pupil dilation, however, the decision to dilate or not is a medical decision to be made by your healthcare professionalThe patient can resume normal activities immediately

The Optomap technology does not require pupil dilation, however, the decision to dilate your eyes is a medical decision to be made by your doctor.
