Q&A with Dr. Singh
Dr. Singh Answers Your Eye Care Questions
Do you use any special technology that no other eye doctors around you use?
We include testing that other offices don’t in our regular private eye examinations: OCT imaging, retinal imaging, pachymetry readings, automated visual field testing. We do this to provide our patients with a comprehensive medical evaluation of their eyes and we always go through the test results with all patients, repeating them on a more consistent basis if there are concerns of change.
Digital Retinal Imaging & OCT Scans
Your Ancaster, ON eye doctor uses 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 optometrist a permanent record of the condition and state of your retina.
This is very important in assisting your Ancaster Family Eyecare 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 a CT scan of the eye. It works using the 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.
A Pachymeter is a medical device used to measure the thickness of the cornea. Pachymetry, the corneal thickness measurement, has a number of uses in comprehensive Optometric care.
Pachymetry is extremely important in determining whether laser eye surgery (PRK, LASIK or Intralase) is suitable for a patient. No matter which type of refractive laser surgery is performed, corneal tissue is removed in the re-contouring of the cornea. The higher the prescription, the more tissue removed. Naturally, there must be a limit to the amount of tissue removed. Pachymetry allows us to determine if a patient has enough tissue to safely have laser surgery.
Corneal pachymetry is an important test in the early detection of certain types of glaucoma. It also can be used in the screening of Keratoconus, a progressive corneal condition.
Our office prides itself on being a progressive optometry office with state of the art equipment and technology. We embrace new technology and advances in eye health while providing the highest level of care and a pleasant environment for our patients.
