FFA - 22 Juli 2024

⁠FFA findings in chronic central serous chorioretinopathy often include:

• Hyperfluorescence in the subretinal space

• Focal choroidal neovascularization

• Hypofluorescence due to retinal pigment epithelial (RPE) atrophy

• Leakage from retinal microaneurysms

Which phase of FFA captures the peak fluorescence intensity of the dye within the retinal vessels?

• Early arteriovenous phase

• Venous phase

• Late phase

• Transit phase

FFA is useful in evaluating retinal vasculitis primarily due to its ability to detect:

• Leaking of dye from retinal capillaries

• Arteriolar wall staining

• Cystoid macular edema

• Venous occlusion

The condition that typically shows "sea fan" neovascularization on FFA is:

• Retinopathy of prematurity

• Sickle cell retinopathy

• Coat's disease

• Retinal artery macroaneurysm

⁠In FFA, late-phase hypofluorescence is a characteristic finding in:

• Serous retinal detachment

• Optic disc pit

• Retinal pigment epithelial tear

• Retinitis pigmentosa

⁠FFA is typically performed with which type of camera?

• Infrared camera

• Digital single-lens reflex (DSLR) camera

• Fluorescence microscope

• Fundus camera

Hyperfluorescence in FFA typically indicates:

• Normal retinal vasculature

• Retinal pigment epithelial window defect

• Optic nerve head drusen

• Optic disc pit

⁠During FFA, the dye is injected intravenously into which arm vein?

• Brachial vein

• Radial vein

• Cephalic vein

• Median cubital vein

Which dye is commonly used in Fundus Fluorescein Angiography (FFA)?

• Indocyanine green

• Sodium fluorescein

• Rose bengal

• Trypan blue

Which characteristic of fluorescein dye is critical for its use in FFA?

• High molecular weight

• Rapid renal clearance

• Water solubility

• Stability under red light
