Module 38:

Optical Coherence Tomography
 

Part 2:

 Quantitative Analysis and scanning techniques
 

 
 

 
   
 

OVERVIEW
 

 
 

Estimated study time:  One hour.

 

Program Level:  Basic and intermediate, with some advanced material.

 

Target Audience:  OMPs with a basic knowledge of OCT operation wanting to learn more about the application and operation of the Zeiss OCT 3 instrument.

 

Pre-requisites:  None.

 

Date of original release:  March 7, 2006
   
 

Description of content:   

 

This module discusses quantitative analysis of the retina with the Zeiss OCT 3 instrument.  Characteristics of a systematic quantitative analysis of the retina are discussed, including scan types and analysis protocols.  Reproducibility issues are discussed, including techniques to improve reproducibility.  Scans for glaucoma analysis are covered also.

 

Instructional  objectives:  Upon completion of  this section,  the student should be able to:

  • describe how the OCT 3 measures retinal thickness

  • list the qualities of a good scan for OCT qualitative analysis

  • identify OCT 3 controls used to maximize scan quality

  • describe how the OCT 3 calculates a retinal volume measurement

  • describe techniques used to improve retina scan reproducibility

  • describe how the OCT 3 measures nerve fiber layer thickness

  • describe how to improve optic nerve scan reproducibility
