Optical Coherence Tomography
Optical Coherence Tomography (OCT)
Optical Coherence Tomography Scanning (OCT) is a noninvasive imaging technique that uses light waves to create detailed cross-sectional imagery of ocular tissues and underlying retinal structures. This imagery allows doctors to more effectively diagnose and treat glaucoma and other retinal diseases like macular degeneration and diabetic retinopathy.
Since 1991, the technology was initially developed; OCT has continually evolved within ophthalmology to provide higher scan densities, better tissue-resolving power, and faster data collection.
BENEFITS
OCT technology creates cross-sectional imagery of the optic nerve and retina with a level of detail that’s simply impossible using other means (10x higher resolution than any other technique available). This technique often leads to earlier detection, a clearer picture of the damage, and a better understanding of progression. This supports earlier, more effective treatments to help better manage the condition.
OCT is noninvasive, requires no injections, and does not involve exposure to high-intensity light. This greatly improves patient safety and comfort.

What to Expect
First, you will dilate your eyes to widen the pupil so it is easier to examine the retina. Next, you will sit in front of the OCT scanner with your head resting on the support to keep it motionless. The OCT machine will then create a scan without making any contact with your eye.
The entire scan will typically only take 10-15 minutes, but due to dilation, your eyes may be sensitive to light for several hours following the scan.
