Advanced Imaging with OCT Technology

Michael Chu Optometrist uses Optical Coherence Tomography (OCT) to provide detailed cross-sectional images of the retina.
This advanced, non-invasive imaging technology allows us to detect and monitor conditions such as glaucoma, macular degeneration and diabetic retinopathy.
OCT helps identify even the smallest changes in the retina, often before symptoms appear.
The scan is quick, painless and requires no contact with the eye.
We recommend OCT imaging especially if you have diabetes, a family history of eye disease or experience sudden changes in vision.

Early Detection for Better Eye Health

OCT is critical in identifying early signs of eye diseases that can progress silently, such as glaucoma, where damage to the optic nerve occurs gradually, often without noticeable symptoms. The high-resolution images allow us to monitor the retinal layers in great detail, tracking changes over time and ensuring treatment plans are adjusted promptly if needed.

This technology is particularly beneficial for patients managing diabetic retinopathy or macular degeneration, as it provides precise information about swelling or abnormalities in the retina. OCT can also detect fluid buildup or changes in the macula, which affects central vision. Regular OCT scans are essential for anyone with chronic eye conditions, allowing for early detection and effective management. Whether it’s part of your annual eye exam or a targeted assessment, OCT imaging keeps your eye care one step ahead, helping protect your vision for the long term.

FAQ's

How is an OCT scan performed?

An OCT scan is a simple, painless procedure that usually takes only a few minutes. You will sit in front of the OCT machine and rest your chin on a support to keep your head steady. The machine will scan your eye using light waves, creating detailed cross-sectional images of the retina and other parts of the eye.

In most cases, the procedure requires no special preparation, and no contact is made with the eye. Occasionally, dilating eye drops may be used to enlarge the pupil, allowing for a clearer view of the retina. During the scan, you may be asked to look at a target or light to help keep your eye steady. The results are typically available immediately, and your optometrist can review the images with you during the same visit.
Do I need an OCT scan even if my vision seems fine?

Yes, OCT scans are beneficial even if you don’t have noticeable vision problems. Many serious eye conditions, like glaucoma or diabetic retinopathy, develop slowly and without obvious symptoms in the early stages. By the time vision loss occurs, damage may already be advanced and harder to treat. Regular OCT scans help detect these conditions early, giving you the best chance for effective treatment and preserving your vision.

People with chronic conditions such as diabetes, hypertension or a family history of glaucoma or macular degeneration should consider OCT imaging as part of their routine eye care. Your optometrist or ophthalmologist can recommend how often you should have an OCT scan based on your risk factors.
Is OCT covered by Medicare or insurance?

In many cases, Medicare and private insurance plans cover the cost of OCT scans if they are deemed medically necessary. This typically applies when the scan is used to monitor an existing eye condition or detect early signs of diseases like glaucoma or diabetic retinopathy. However, routine OCT scans performed during general eye exams without specific medical concerns may not always be covered.

It’s a good idea to check with your healthcare provider or insurer to confirm coverage details and eligibility. If OCT isn’t fully covered, some optometry practices offer payment plans or packages to make this valuable diagnostic tool more accessible.
