Eye Care Imaging and Screening

At Twenty20 Vision Center, we use the latest in retinal imaging technology

When you visit your eye doctor, you want to know that the optometry office has the best and most advanced technology to diagnose eye disease, and screen for possible vision problems.

Digital Retinal Imaging & OCT Scans

Corneal mapping

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. Since the cornea is normally responsible for some 70% of the eye’s refractive power, its topography is of critical importance in determining the quality of vision.

The three-dimensional map is therefore a valuable aid to the examining ophthalmologist or optometrist and can assist in the diagnosis and treatment of a number of conditions; in planning refractive surgery such as LASIK and evaluation of its results; or in assessing the fit of contact lenses. A development of keratoscopy, corneal topography extends the measurement range from the four points a few millimeters apart that is offered by keratometry to a grid of thousands of points covering the entire cornea. The procedure is carried out in seconds and is completely painless.

Digital retinal imaging

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.

  • 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

Optical Coherence Tomography (OCT) Scan

An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is a quick, non-invasive, and painless 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.

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.

LipiFlow®

LipiFlow® is an FDA-approved treatment designed to address Meibomian gland dysfunction (MGD), which is the primary cause of dry eye. This treatment works by applying gentle heat and massage to the inner eyelids, helping to restore normal oil production and enhance tear quality.

Patients are assessed for MGD using LipiView®, a specialized imaging device that allows for a detailed view of the Meibomian glands. If a patient is found to be a suitable candidate for LipiFlow®, the treatment can be performed on the same day.

Advanced Technology Used at Twenty20 Vision Center

Olleyes VisuALL

Olleyes VisuALL is a portable, virtual reality-based diagnostic tool used in ophthalmology and optometry to assess various aspects of visual function. It leverages advanced virtual reality (VR) technology to conduct a range of visual tests in a compact and user-friendly format.

iCare Tonometer

This accurate painless puffless tonometer measures the eye’s intra-ocular pressure (IOP).

Maestro Robotic OCT

The Maestro Robotic OCT (Optical Coherence Tomography) is an advanced diagnostic imaging device used primarily in ophthalmology to capture detailed cross-sectional images of the retina, optic nerve, and other structures within the eye. It combines high-resolution imaging with automated features that simplify the imaging process for both the clinician and the patient.
