High-Level Technology Means High-Level Care

Cutting Edge Technology

Retinal Imaging

Vision is our most precious sense so we should do everything we can to preserve it. Dr. Bansal believes in annual eye exams with retinal imaging for the optimal long term care of our eyes. That way she can be sure to catch any vision threatening conditions at the first sign.  

It is especially recommended if you have systemic diseases such as diabetes, high blood pressure, high cholesterol, are on any high risk medications, or have a family history of these or other conditions such as glaucoma or macular degeneration.  

B-Town Eyecare offers the best in retinal imaging with the Optovue iCam retinal camera to all patients. This state of the art technology allows us to examine the retina more carefully. The photo takes only a few seconds, it provides a permanent record to compare and track potential eye disease and offers a static view of the retina that Dr. Bansal can review with you and use as a baseline in the future for comparison.

An example of OCT imaging

Ocular Coherence Tomography (OCT)

Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of your retina. With OCT, Dr. Bansal can see each of the retina’s distinctive layers. This allows her to map and measure their thickness. These measurements help with diagnosis. They also provide treatment guidance for glaucoma and diseases of the retina. These retinal diseases include age-related macular degeneration (AMD) and diabetic eye disease.

You will sit in front of the OCT machine and rest your head on a support to keep it motionless. The equipment will then scan your eye without touching it. Scanning takes about 5 – 10 minutes. If your eyes were dilated, they may be sensitive to light for several hours after the exam.OCT is useful in diagnosing many eye conditions, including:

  • Macular hole
  • Macular pucker
  • Macular edema
  • Age-related macular degeneration
  • Glaucoma
  • Central serous retinopathy
  • Diabetic retinopathy
  • Vitreous traction

The OCT is often used to evaluate disorders of the optic nerve as well. The OCT exam helps your ophthalmologist see changes to the fibers of the optic nerve. For example, it can detect changes caused by glaucoma.

iWellness Screening

Sight threatening diseases such as glaucoma, macular degeneration, diabetic retinopathy and others often have no outward signs or symptoms, which is why eye exams, including a thorough retinal evaluation, are important to protect vision. In an effort to provide a more thorough eye exam, we are excited to let you know that during your next visit to B-Town Eyecare, you will experience the benefits of the latest advancement in primary eyecare – the iWellnessExam™ SD- OCT retinal scan as part of our comprehensive eye exams.

The iWellness Exam uses breakthrough technology called spectral domain optical coherence tomography or SD-OCT. Similar to an MRI or CT scan, the iWellness Exam captures high definition cross sectional images of your retina, which is the back of your eye, and allows Dr. Bansal to see in unprecedented clarity what may be invisible with traditional examination methods.

Many eye problems can develop without warning and progress without symptoms. In early stages, you may not even notice a change in your vision. But sight threatening conditions and diseases such as macular degeneration, glaucoma, diabetic retinopathy and others can be detected with a thorough evaluation of the retina, including the iWellness Exam. 

The iWellness Exam is a fast, painless procedure that provides:A detailed SD-OCT scan report to show a healthy eye or detect very early signs of disease.

  • A retinal thickness map and ganglion cell complex assessment giving Dr. Bansal detailed information simply not available with other methods.
  • The opportunity for you to view and discuss your iWellness Exam report with Dr. Bansal at the time of your exam.
  • A permanent record for your file, which allows Dr. Bansal to compare your iWellness Exam reports each year to look for changes.

As part of your pre-examination work-up, our technician will perform this test which Dr. Bansal will review with you during your examination. The results of this exam will become a part of your permanent patient record.

Humphrey Visual Field Analyzer

The Humphrey visual field is a diagnostic device used to test a patient’s complete “visual field,” which includes the peripheral vision. It is a simple, painless, out-patient procedure and takes only minutes. It is based on automated perimetry, where repeated light stimuli of varying intensities appear in different parts of the field. Fields are charted on the basis of patient’s perception of these lights. The results obtained from the patient are then compared with those of the age matched normal population and the amount of damage is quantified. This quantified data allows for the early diagnosis and management of countless conditions. Progression is now easily monitored. This test is invaluable in diagnosing, and monitoring the treating patients with glaucoma, where peripheral vision irreversibly lost without symptoms until later stages. The Humphrey Visual Field is currently the gold standard for managing glaucoma. It is also useful in many neurological conditions and in conditions affecting the optic nerve of the eye, such as intracranial tumors, strokes or multiple sclerosis! In an optometric practice, the Humphrey Visual Field Analyzer is accepted as the best diagnostic tool for visual field analysis available.
