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.
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.
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.

At Schwartz Eye Care, your exam is computer enhanced. We begin with the most advanced auto-refractor on the market. This gives us a quick, painless, objective measurement of a person's refractive error.
The M3 is totally automatic when aligning, tracking and focusing on the patients eye. It uses super-luminescent diode technology to more accurately measure patients with cataracts, corneal opacities and post-lasik.
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.
At Schwartz Eye Care, we use this technology in the the fitting and evaluation of Vision Shaping with orthokeratology as well as all types of rigid gas permeable contact lenses (RGPs) including scleral lenses. We manage corneal dystrophies and degenerations like keratoconus. Additionally our topographer helps in the preoperative and postoperative refractive surgery evaluation and treatment for procedures such as LASIK or PRK.
All eye care practices use a phoropter to determine a patient's prescription, but not all practices use an automatic one. The automated version of the machine enhances patient comfort with its adjustable properties as well as patient response with its side by side comparison of images. A traditional phoropter relies on the memory of two images, "here's image 1" and "here's image 2. Do you like 1 or 2?" The automated phoropter allows the patient to compare the two images simultaneously to improve accuracy and limit error.
The Optikam is an advanced optical system that gathers multiple points of measure for fitting eyeglasses in just one photo. In one picture, ten measurements create the base for custom eyewear to enhance vision and comfort. Our patients can compare up to four pictures at a time to help pick the best frame to suit his/her features as well. It is also possible to email these photos to friends and family to assist in the selection process.
