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.

Attention:

Due to the COVID-19 crisis, the College of Optometrists of Ontario has recommended to restrict eye care to urgent care cases only.

Your safety and well-being are of the greatest importance to us.

Our office will be restricting our appointments and hours accordingly.

It is our belief that we want to limit the number of patients that should be going to the emergency room at this time, so we want to help by seeing those eye emergencies when we can.

Please do not come to our office if:

You have tested positive for COVID-19 virus.

You have been exposed at any point to a person who has tested positive for COVID-19

You are feeling ill in any way (not just COVID-19) symptoms

You have returned to Canada from out of country and have not completed a 14 day period of self-isolation.

Please note, that all phone calls will still be answered in normal daytime business hours and triaged accordingly by Dr. Ruhl. As well, email requests/concerns can be sent 24 hours/day, 7 days a week, and we will attempt to return a message within 24 hours. (If a response is not received in this time period and /or this is an ocular emergency, then you should proceed to the emergency department for assessment.)

If an appointment is necessary, then Dr. Ruhl will arrange for the time for the appointment at the office. If a patient comes to the office, we request that only the patient comes in the office and please leave all family, friends, drivers, etc… outside the office unless the patient requires them for assistance.

All patients must wash their hands thoroughly upon entering the office for their appointment.

To those patients wishing to pick up glasses, we can possibly arrange a time (and place for pickup) via a phone call to the office.

At this time, contact lenses can be ordered as well. When possible, we will have the contact lenses shipped directly to your residence from the manufacturer. In other cases, we will attempt to deliver them to your house ourselves. We will arrange for payment when you call the office.

Thank you for your consideration in these difficult times.

Dr. Ruhl

CONTACT LENSES CAN STILL BE ORDERED!

You can still order contact lenses and have them delivered right to your door at no charge in most cases. Call the office during daytime office hours or send an email and we’ll get right back to you and have your order arranged!
