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.

Daytona Optomap Retinal Imaging Camera

The Optos Daytona is a scanning retinal imaging instrument that is able to take ultra-wide images of a patient’s retina. Typically the size of the pupil will limit any imaging system or camera from seeing many parts of the internal lining of the patient’s eye called the retina. The Optos Daytona uses special technology in Ellicott City, MD to capture retinal images as if it were taking them from inside the eye.optos daytona_1

How much of the retina, does the Optos Daytona look at and give imaging for?
Most cameras that image the retina without pupil dilation can image about 60 degrees. The Optos Daytona is able to show our doctors roughly 270 degrees of a patient’s retina without the use of dilating drops. Most cameras can capture an area of the retina known as the posterior pole (that include the macula and optic nerve head), but it is only with the Daytona imaging system that we are able to see much more of the peripheral retina.

What types of eye diseases and disorders can be discovered?
The Optos Daytona helps our doctors to diagnose eye diseases such as glaucoma, macular degeneration and diabetic retinopathy. We are able to monitor “freckles” in the back of the eye known as a choroidal nevus. We’ve discovered retinal melanomas and peripheral abnormalities such as retinal holes, retinal tears and retinal detachments. It can also sometimes help us to see vitreal floaters. It also allows us to monitor patients on a drug called Plaquenil that is often used in rheumatoid arthritis and can cause retinotoxicity.

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.
