Advanced Retinal Imaging

OCT & Optomap Scans at Watchfield Opticians

More than just an Eye Test

In addition to all the standard test equipment Watchfield Opticians has the very latest in Optical Coherence Tomography and Optomap Imaging equipment enabling a record of highly detailed images of the separate layers of the retina to be captured because being able to pinpoint any abnormalities to a specific layer provides clues about the possible cause. This can help differentiate between conditions that have very similar clinical signs and symptoms but require different treatment, such as for dry and wet macular degeneration.

These scans only take a few moments.  You will be sat in a chair at the machine and there will be a momentary bright flash after which our Optometrist will be able to show you and discuss the findings with you. 

With both these imaging techniques the images are securely kept on your file.  The digital baseline produced will be easy to compare with future results making early diagnosis of any changes easier. 

 

To conclude the eye test the Optometrist will summarise the findings and offer advice which might include treatments for eye conditions or options for glasses and spectacle lenses to suit your lifestyle needs or contact lenses may even be suggested.

Advanced Retinal Screening at Watchfield Opticians

Ultra Wide Field Imaging

Optomap/Optos

Regular detailed examination of the inside of the eye – the retina, is critical to eye health. Your Optometrists use several techniques to examine the retina including looking into the eye, usually after dilating and the use of special cameras for imaging inside the eye. Until recently, most ophthalmic cameras could only photograph about 20% of the retina at a time. We now know that many eye diseases occur or begin at the outer edges of the retina, (“the periphery”), so examining this area is extremely important. 

Because seeing the entire retina is so important at Watchfield Opticians we have invested in the most advanced camera for ultra wide field imaging system. In a single, quick shot, this camera produces “Optomap” photos of about 82% of the retina. These images provide superior visibility of the retinal periphery allowing us to document, show you, and follow pathology that could not be seen with traditional eye cameras. 

The exam is quick and painless and combined with the thorough eye exams our optometrists are trained to provide this advanced technology offers a new level of diagnostic confidence.

OCT stands for Optical Coherence Tomography and is a complex technology used to measure the eye and particularly the layers of the retina. The retina is the light sensitive area at the back of the eye, equivalent to film in a camera or a sensor in a digital camera. 

An OCT scan is similar to an MRI or CAT scan for the eyes. OCT technology can image in 3D allowing your practitioner to see, sometimes for the first time, problems within your eye that could not easily be seen before.

  • How often should I have an eye exam?
    It is recommended to have a comprehensive eye exam every one to two years, depending on your age, risk factors, and overall eye health. Your eye care professional can determine the ideal frequency for your specific needs.
  • What are the common signs and symptoms of eye problems in adults?
    Common signs and symptoms of eye problems in adults include blurred vision, difficulty seeing at night, eye strain or fatigue, redness, itching or dryness, eye pain or discomfort, floaters or flashes of light, and frequent headaches.
  • Can digital screens and prolonged computer use harm my eyes?
    Extended periods of staring at digital screens can cause digital eye strain, also known as computer vision syndrome. It can lead to symptoms like dry eyes, blurred vision, headaches, and neck or shoulder pain. Following the 20-20-20 rule (taking a 20-second break every 20 minutes to look at something 20 feet away) can help alleviate these symptoms.
  • How can I prevent or manage dry eyes?
    To prevent or manage dry eyes, use lubricating eye drops, avoid dry environments or excessive airflow, take regular breaks during prolonged screen time, and consider using a humidifier in your home or office. It's also important to stay hydrated and avoid rubbing your eyes.
  • How do I take care of contact lenses?
    Proper care and maintenance of contact lenses are crucial to prevent eye infections and ensure clear vision. It typically involves cleaning and disinfecting the lenses, storing them correctly, and adhering to a recommended replacement schedule. Follow the instructions provided by your eye care professional and the lens manufacturer.
  • How is Ultra Wield Field Imaging different from an OCT Scan?
    Ultra Wield Field Imaging is a wide-field retinal imaging technology that captures high-resolution, panoramic images of the retina. Unlike an OCT Scan, which provides cross-sectional images, Ultra Wield Field Imaging captures a wide-angle view of the retina, including the peripheral areas. This imaging can help detect retinal abnormalities, peripheral lesions, and vascular disorders.
