Optical Coherence Tomography (OCT)
Optical Coherence Tomography Scanning (OCT) is a non-invasive 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, as well as other retinal diseases like macular degeneration and diabetic retinopathy.
Since 1991, when the technology was originally developed, OCT has continually evolved within ophthalmology to provide higher scan densities, better tissue resolving power, and faster data collection.
Optical Coherence Tomography – Benefits
OCT technology creates cross-sectional imagery of the optic nerve and retina with a level of detail that’s simply not possible 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 non-invasive, requires no injections, and includes no exposure to high-intensity light. This provides for much improved patient safety and comfort.
Optical Coherence Tomography – What to Expect
You will first have your eyes are dilated 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 normally only take 10-15 minutes, but your eyes may be sensitive to light for several hours following the scan due to being dilated.
