Optical Coherence Tomography in Rancho Cucamonga

Optical Coherence Tomography in Rancho Cucamonga — Precision Imaging for Your Eye Health

Optical coherence tomography in Rancho Cucamonga — commonly called OCT — is one of the most powerful diagnostic tools available in modern eye care. At Opticore Eye Group, we use OCT imaging to create detailed cross-sectional images of your retina, allowing our doctors to see individual layers of tissue that can't be visualized any other way. This technology plays a critical role in detecting and monitoring conditions like glaucoma, macular degeneration, and diabetic retinopathy at their earliest, most treatable stages.

What Is OCT and How Does It Work?

OCT uses light waves to take high-resolution images of the layers of your retina — similar to how ultrasound uses sound waves to create images of internal structures. The scan is completely non-invasive and painless, takes only a few minutes, and typically doesn't require pupil dilation. The resulting images give your doctor a precise map of your retinal thickness and structure, which can be compared to baseline scans at future visits to track any changes over time.

Conditions Evaluated With OCT Imaging

OCT imaging is used to evaluate and monitor:

Glaucoma — measuring retinal nerve fiber layer thickness to detect early damage
Macular degeneration — identifying drusen, fluid, and structural changes in the macula
Diabetic retinopathy — detecting fluid and retinal swelling from diabetic eye disease
Macular holes and epiretinal membranes — precise structural assessment
Vitreomacular traction — evaluating the interface between the vitreous and retina

OCT may be performed as a routine part of your comprehensive exam or recommended specifically for monitoring a known condition.

Coverage & How to Add OCT to Your Visit

OCT imaging is often included as part of a comprehensive eye exam or billed separately when used for medical diagnosis or monitoring. Coverage depends on whether it's being performed for routine screening or medical management of a specific condition — your vision or medical insurance may apply. Call (909) 752-0682 and we'll check your benefits before your visit. OCT is available at our Town Center Square office in Rancho Cucamonga.
