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
We 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 your Optometrist 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.
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.
Daytona OPTOS Retinal Exam
The eye doctors at Strong Vision Center are proud to introduce the latest cutting edge technology in retinal imaging, the Optos Daytona Optomap OCT. This amazing device allows your eye doctor to see retinal, optic nerve and cornea structures not visible through regular exam methods by using light to provide a high resolution scan meant to pick up early signs of structural change or disease. This allows your eye doctor to see even the smallest changes in the retina and optic nerve with greater accuracy, and much higher definition, making early and accurate detection of common sight threatening eye conditions such as glaucoma, macular degeneration and diabetic retinopathy, easier than ever before.
Advanced Eye Exams in Cypress, TX
While traditional imaging technologies are usually able to scan around 15% of your retina at a time, The OPTOS Optomap is able to scan in a stunningly large 200 degree arc, capturing about 80% of your retina in one panoramic scan. This allows for a wider and more accurate view of the retina than with less advanced scans. This scan will provide you and your eye doctor with an extremely detailed picture of your eye that will act as a valuable road map of your overall eye health.
The high resolution images produced by the Optos Daytona Optomap OCT provide a personal benchmark for each person’s ocular health and helps detect sudden changes through the years, and since the images show up automatically on a computer monitor, you are able to see for yourself everything the doctor is telling you about your eye health, allowing you to take an active role in preserving your valuable sense of sight.
Suitable for Family Eye Exams
The patient experience is also fast, easy and painless, with a noticeable focus on maximizing patient convenience and eliminating patient discomfort. Nothing touches your eye at any time and it is suitable for the whole family, from youngest to oldest. The exam consists of taking a brief look into the device one eye at a time. You will see a comfortable flash of light, which lets you know the image of your retina has been taken, and you’re done!
The doctors at Mill Creek Vision recommend an Optomap OCT scan to every patient, “The quality of the Optomap scan and the amount of information we can get from this scan is of great value. Often, we find that a patient thinks his or her vision is very good, but when we administer the optomap scan, we find that, at the cellular level, there are important changes that signify possible issues that may otherwise have gone unnoticed. Early detection and effective prevention are the most important parts of beating any disease, and this is where the Optomap shines!”
