Lesson 2: Before the scanning Copy

Optical coherence tomography allows for clinical observation, measurement, and identification of structures that otherwise are not easily visible.

It also shows various types of lesions with altered morphology, altered reflectivity, and/or optically blank areas.

It is worthwhile to recall that with the OCT, Optometrists can do the following:

• Measure retinal thickness.
• Measure the retinal nerve fibre layer.
• Measure the volume of the retina.
• Create retinal thickness maps.
• Isolate and create maps of the internal limiting membrane and the retinal pigment epithelium.
• Measure various parameters of the optic disc.
• Display three-dimensional views.
• Provide classic C-scan analysis.
• Create horizontal tissue sections.
• And offer an RPE-fit function that provides a view of a tissue section.
