The macula OCT: An Overview
madhusudan davda
Superspeciality Retina Care Centre
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
Why do we want an OCT?
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
check the demographicscheck the scan typecheck the signal strengthcheck the thickness mapcheck the subfield thicknessread the actual OCT imagecheck the scan directionstudy different layerscheck for missing zonestake multiple scans using
different protocolsclinically examinereport the scan
always see the whole scan, scroll through
questions to be askedis 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?
