What is an OCT screening?

We just upgraded our eye examination technology! While we previously did retinal imaging as part of our comprehensive eye health examinations, we now offer OCT scans in addition!

Patients may have heard this term OCT while doing an eye exam; sometimes it can be a little overwhelming when some more in-depth tests are being conducted. Dr. Natalia Nowakowska explains in more detail about our new scan and the benefits of doing them.

 OCT, or Optical Coherence Tomography, is an advanced screening procedure which, analogous to an ultrasound, creates a cross sectional image of your eye. It uses non-invasive light technology allowing for a scan that is precise, quick, and painless.

Standard retinal imaging photography creates a 2D retinal image of the surface of your retina. The OCT screening takes things beyond the retinal surface creating a sectional model, which allows us to obtain 3D geometrical data. This enables us to check your eye health layer by layer. 

Seeing beneath the surface of the retina plays an important role in the detection of eye conditions such as: 

- Glaucoma

- Diabetic Retinopathy

- Macular Degeneration

- Macular Hole

- Optic Nerve Diseases

- Vitreous Detachments

Examination of the retina at this level has revolutionized the  diagnosis of various retinal conditions and treatments.
