OCT Scan and Retina Knowledge Quiz

Which of the following does not belong to the causes of such deviations in the retina?

• Intraretinal fluid

• Pigment change in the RPE

• Intraretinal exudates

• Subretinal fluid

The steps for assessing an OCT scan are in the following order:

• Assess scan quality; Grade entire scan profile; Evaluate foveal profile; Identify 'foveal cross section'; Assess the different retinal layers

• Assess scan quality; Grade entire scan profile; Identify 'foveal cross section'; Evaluate foveal profile; Assess the different retinal layers

• Grade entire scan profile; Assess scan quality; Evaluate foveal profile; Identify 'foveal cross section'; Assess the different retinal layers

• Assess scan quality; Identify 'foveal cross section'; Grade entire scan profile; Evaluate foveal profile; Assess the different retinal layers

During the last step of the routine from the knowledge clip, you always start observing the transitions of the retinal layers at:

• The RPE

• The vitreous body

• The macula

• The lamellar structures

What is an example of a normal structure that can cause artifacts on an OCT cross-section scan?

• Retinal pigment

• Retinal blood vessel

• Retinal nerve fiber

• Retinal fluid

A normal profile of the foveal area on an OCT photo has a somewhat straighter course at the level of:

• The outer layers of the retina

• The inner retinal band

• The inner layers of the retina

• The outer retinal band

A good cross-section image of the fovea is present when:

• The RPE and the inner plexiform layer meet in the center of the fovea

• The nerve fiber layer and the outer plexiform layer meet in the center of the fovea

• The RPE and the inner plexiform layer meet in the center of the fovea

• The nerve fiber layer and the inner plexiform layer meet in the center of the fovea

The location where the OCT scan should be placed is best determined by a:

• Time domain OCT scan

• 30° HR line scan

• Fundus photo

• Cross-section OCT scan

Which layer of the retina is shaded with a red line here?

• Henle's fiber layer

• External limiting membrane

• Outer plexiform layer

• Middle limiting membrane

On this OCT cross-section photo, hyperreflective dots are visible (see the white arrows). These are:

• Blood vessels

• Exudates

• Cysts

• Drusen

The structures of the inner layer of the retina are in the following order:

• A = Retinal Nerve Fiber Layer; B = Outer Nuclear Layer; C = Outer Plexiform Layer; D = Inner Nuclear Layer; E = Inner Plexiform Layer; F = Ganglion Cell Layer; G = External Limiting Membrane

• A = External Limiting Membrane; B = Outer Nuclear Layer; C = Outer Plexiform Layer; D = Inner Plexiform Layer; E = Inner Nuclear Layer; F = Ganglion Cell Layer; G = Retinal Nerve Fiber Layer

• A = External Limiting Membrane; B = Outer Nuclear Layer; C = Outer Plexiform Layer; D = Inner Nuclear Layer; E = Inner Plexiform Layer; F = Ganglion Cell Layer; G = Retinal Nerve Fiber Layer

• A = External Limiting Membrane; B = Outer Plexiform Layer; C = Outer Nuclear Layer; D = Inner Nuclear Layer; E = Inner Plexiform Layer; F = Ganglion Cell Layer; G = Retinal Nerve Fiber Layer
