The macula OCT: An Overview

Follow up : post treatment in cases CSME, ARMD. check the demographics, scan type, signal strength, thickness map, subfield thickness read the actual OCT image,, scan direction, study different layers. check for missing zones take multiple scans using different protocols. study the overall report starting from name, date, signal strength etc .<br>Visit for more info :- https://mumbaieyeretinaclinic.com/

Presentation Transcript

  1. The macula OCT: An Overview madhusudan davda Superspeciality Retina Care Centre

  2. Why do we want an OCT? • to check if there is a pathology: unexplained DOV, media haze (pre cataract), as routine work up for MFIOLs • document a clinical pathology? ERM, FTMH • follow up : post treatment in cases CSME, ARMD… • prognosticate a disease : almost all pathologies

  3. What to look for in an OCT? • What OCT is it? macula, ONH, RNFL anterior • What is the scan Type: raster lines, macular cube, radial • study the overall report starting from name, date, signal strength etc

  4. check the demographics check the scan type check the signal strength check the thickness map check the subfield thickness read the actual OCT image check the scan direction study different layers check for missing zones take multiple scans using different protocols clinically examine report the scan

  5. always see the whole scan, scroll through

  6. questions to be asked • is there a pathology? • what is the level at which it is? • what are the morphologic changes visible? • can we predict duration & prognosis? • is the disease active/inactive?

  7. Normal OCT: layers

  8. Normal OCT: zones

  9. The normal OCT • vitreous • vitreo retinal interface • neurosensory retina • retinal pigment epithelium • choroid
