OCT-A vs. FFA: The Ultimate Board Exam Showdown! ๐๏ธ๐
If youโre 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 hereโit allows us to see the superficial and deep capillary plexuses separately.
Invasiveness: No needle, no dye, no nauseaโOCT-A allows for unlimited repeat imaging.
Which one do you rely on more for daily clinical decisions? Letโs discuss in the comments! ๐

OCT-A Pearls for Board
More in the full lecture: https://youtu.be/0ycr6JLZER4?si=b6L5QOJzVQxncouk
๐ฅ 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.
๐ฅ 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.
๐ฅ 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.
๐ฅ Pearl 4: Projection artifacts mimic Type 1 MNV. Always use projection-resolved algorithms and cross-check with structural B-scan before diagnosing neovascularization.
๐ฅ 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.
๐ฅ 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.
๐ฅ 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.
๐ฅ 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.

โ๐จโโ๏ธ๐ฉโโ๏ธ To my colleagues in the Retina Squad Academy:
Patient education is half the treatment! We all know how challenging it is to fully explain Diabetic Retinopathy, intravitreal injections, and panretinal photocoagulation (PRP) during a busy, fully-booked clinic.
โI created this comprehensive video entirely in Arabic as an educational tool for your clinics. Feel free to share this link directly with your Arabic-speaking patients or in your clinic WhatsApp groups. It breaks down the complex medical concepts into simple, reassuring terms to save you time and improve patient compliance. Let's protect their vision together! ๐ค
