OCT (Ocular Coherence Tomography)

Glaucoma Diagnosis Advances With Ocular Coherence Tomography (OCT)

The Ocular Coherence Tomographer (OCT) provides high resolution imaging of ocular tissues. As our eye doctor can explain during your next eye exam, OCT can measure retinal nerve fibre layer tissue as will as macula thickness and is used in diagnosis of glaucoma as well as macular conditions such as macular degeneration and edema.

The technique is analagous to ultrasound except is uses light (843nm) instead of sound waves to allow exceptionally high resolution images.
