OCT-A vs. FFA: The Ultimate Board Exam Showdown! ๐Ÿ‘๏ธ๐Ÿ“–

If youโ€™re preparing for the FEBOS-R, FRCS, or any ophthalmology board exam, you know this comparison is a favorite among examiners. While FFA has been our "gold standard" for decades, OCT-A is changing the game with its depth-resolved, non-invasive capabilities.

Key Takeaways:

Leakage: FFA is still king. If you need to see active leakage, you need the dye.

Layers: OCT-A wins hereโ€”it allows us to see the superficial and deep capillary plexuses separately.

Invasiveness: No needle, no dye, no nauseaโ€”OCT-A allows for unlimited repeat imaging.

Which one do you rely on more for daily clinical decisions? Letโ€™s discuss in the comments! ๐Ÿ‘‡

OCT-A Pearls for Board

More in the full lecture: https://youtu.be/0ycr6JLZER4?si=b6L5QOJzVQxncouk

๐Ÿ”ฅ Pearl 1: OCT-A detects FLOW, not leakage. FFA detects leakage and perfusion. They are complementary โ€” not competitive. Always know which question you're asking before choosing your modality.

๐Ÿ”ฅ Pearl 2: The Outer Retinal Avascular Zone should be EMPTY on OCT-A. Any flow signal there = pathological neovascularization. This is how you spot Type 2 MNV in one look.

๐Ÿ”ฅ Pearl 3: Type 3 MNV originates from the DCP โ€” look for intraretinal flow extending downward, always in a background of drusen. IR reflectance showing drusen + DCP flow = Type 3 until proven otherwise.

๐Ÿ”ฅ Pearl 4: Projection artifacts mimic Type 1 MNV. Always use projection-resolved algorithms and cross-check with structural B-scan before diagnosing neovascularization.

๐Ÿ”ฅ Pearl 5: Choriocapillaris flow voids on OCT-A appear BEFORE geographic atrophy is visible on FAF or structural OCT. This is the earliest detectable AMD change we have today.

๐Ÿ”ฅ Pearl 6: Ghost vessels on OCT-A after anti-VEGF = inactive treated CNV. Visible on OCT-A but no active flow. This is a treated scar โ€” do not re-inject based on OCT-A alone without structural OCT evidence of activity.

๐Ÿ”ฅ Pearl 7: DCP FAZ is larger than SCP FAZ in normal eyes. Disproportionate DCP FAZ enlargement in DME = macular ischemia component โ€” explains poor anti-VEGF response in some patients.

๐Ÿ”ฅ Pearl 8: In chronic CSC โ€” always look for secondary Type 1 MNV on OCT-A. It develops silently, below the RPE, and is easily missed on clinical exam alone.

No dye. No injection. No waiting. Just pure vascular architecture โ€”
captured in seconds. OCT-A didn't just change how we image the retina.
It changed how we think about retinal disease.

In this lecture, we go from the physics of decorrelation signal all the way
to clinical mastery of the four retinal slabs, the FAZ, MNV classification,
artifacts that will trap you on the board exam โ€” and exactly why the
outer retina must always be dark.

Whether you're preparing for the FEBOS-R, reviewing for your FRCOphth,
or just want to finally understand OCT-A properly โ€” this is the lecture.

โ€ข The physics of OCT-A โ€” motion contrast, decorrelation signal, SSADA vs OMAG
โ€ข The four retinal slabs โ€” SCP, DCP, Outer Retina, Choriocapillaris
โ€ข The FAZ โ€” normal values, what enlargement means, and which diseases affect it
โ€ข MNV Classification โ€” Type 1, Type 2, Type 3 (the former "CNV" finally
made sense by OCT-A)
โ€ข OCT-A in AMD, Diabetic Retinopathy, RVO, and CSC
โ€ข Artifacts โ€” projection, motion, segmentation, shadow โ€” and how to spot
each one
โ€ข The 5 key limitations of OCT-A vs FFA โ€” and when to use each

โšก HIGH-YIELD FEBOS-R PEARLS:

๐Ÿ”ฅ PEARL 1: The outer retina slab must be completely dark on OCT-A in
healthy eyes. Any flow signal in the outer retina = abnormal
neovascularization. Full stop.

๐Ÿ”ฅ PEARL 2: OCT-A does NOT show leakage. Vascular permeability = FFA.
If the exam asks which modality shows vascular permeability โ€” the answer
is never OCT-A.

โ€‹When reading an OCT, many people just look at the Ellipsoid Zone (EZ) and stop there. But to truly master macular pathology, you need to recognize all 4 hyperreflective outer retinal bands!

โ€‹Letโ€™s break them down from top to bottom:

1๏ธโƒฃ Band 1: External Limiting Membrane (ELM) - Not a true membrane, but the zonular junctions between Mรผller cells and photoreceptors. An intact ELM means the photoreceptor cell bodies are surviving. ELM disruption is your earliest warning sign of damage!

2๏ธโƒฃ Band 2: Ellipsoid Zone (EZ) - The true star of the show (formerly the IS/OS junction). It represents the mitochondria-rich inner segments. This is your ultimate Visual Acuity Predictor. (Intact = Good prognosis | Disrupted = Permanent damage).

3๏ธโƒฃ Band 3: Interdigitation Zone (IZ) - The contact point between cone outer segments and RPE microvilli. Subtle, but critical in cone dystrophies.

4๏ธโƒฃ Band 4: RPE/Bruchโ€™s Complex - The solid foundation layer.

โ€‹๐Ÿ”ฅ High-Yield Board/FEBOS-R Pearl:

Do NOT confuse the spaces around the RPE!

๐Ÿ‘‰ Sub-RPE Space (Between RPE & Bruch's): This is where Drusen live and where Type 1 MNV (Neovascularization) hides.

๐Ÿ‘‰ Subretinal Space (Between RPE & Photoreceptors): This is where Subretinal Fluid (SRF) accumulates and where Type 2 MNV grows.
