Digital Retinal Imaging
The optometrists at TSO Katy Ranch 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 eye doctor 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.
Visual Field Testing
A visual field test measures how much 'side' vision you have. It is a straightforward test, painless, and does not involve eye drops. Essentially lights are flashed on, and you have to press a button whenever you see the light. Your head is kept still and you have to place your chin on a chin rest. 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. Your optometrist may ask only for a driving licence visual field test, which takes 5-10 minutes. If you have just asked for a driving test or the clinic doctor advised you have one, you will be informed of the result by the clinic doctor, in writing, in a few weeks.
Normally the test is carried out by a computerised machine, called a Humphrey. Occasionally the manual test has to be used, a Goldman. For each test you have to look at a central point then press a buzzer each time you see the light.
OPTOS Retinal Exam
Optomap: Ultra-wide field digital retinal imaging introduced by Optos is increasingly becoming a standard of care for primary eye care providers. The Optomap technology is designed to simultaneously capture a digital image view of the retina from central pole to periphery. The images allow the screening of a primarily healthy patient base and provide two tracks in the system to support wellness and medical imaging procedures.
Annual eye exams are vital to maintaining your vision and overall health. We offer the optomap® Retinal Exam as an important part of our eye exams. The optomap® Retinal Exam produces an image that is as unique as you fingerprint and provides us with a wide view to look at the health of your retina. The retina is the part of your eye that captures the image of what you are looking at, similar to film in a camera.
Many eye problems can develop without you knowing. You may not even notice any change in your sight. But, diseases such as macular degeneration, glaucoma, retinal tears or detachments, and other health problems such as diabetes and high blood pressure can be seen with a thorough exam of the retina.
An optomap® Retinal Exam provides:
- A scan to show a healthy eye or detect disease.
- A view of the retina, giving your doctor a more detailed view than he/she can get by other means.
- The opportunity for you to view and discuss the optomap® image of your eye with your doctor at the time of your exam.
- A permanent record for your file, which allows us to view your images each year to look for changes.
The optomap® Retinal Exam is fast, easy, and comfortable for all ages. To have the exam, you simply look into the device one eye at a time and you will see a comfortable flash of light to let you know the image of your retina has been taken. The optomap® image is shown immediately on a computer screen so we can review it with you.
Please schedule your optomap® Retinal Exam today at our vision center.

The first and only universal measuring system that allows you to obtain every possible parameter needed for today's individualized lenses. Only the Visioffice system measures a revolutionary new parameter—the real 3D position of the Eye Rotation Center for each eye—so we can dispense Essilor's unique eyecode™ lenses. With eyecode lenses, you get the most precise vision possible, no matter where you look through the lens—instantly and effortlessly.
Visio-Office is an all-in-one system for a full range of measurements for every patient — from single vision to the most sophisticated progressive designs:
- Eye Rotation Center: Each of our eyes rotates around a fixed point called the Eye Rotation Center (ERC). Only Visioffice measures the real 3D position of each eye's unique ERC to create the most individualized lenses possible—eyecode lenses
- Natural head posture: Is unique to each person and can vary widely, impacting lens performance
- Eye position: Monocular PDs, fitting heights Wearing parameters: Vertex distance, wrap angle, pantoscopic angle
- Visual behavior: Natural head posture and head/eye movements are measured and recorded
- Frame measurements: A and B measurements, DBL
