Translational retinal imaging Flashcards
Optical Coherence Tomography (OCT):
A. uses low-coherence light to produce high-resolution cross-sectional images of the retina
B. employs a laser beam to create detailed images of the retina,
A
Confocal Scanning Laser Ophthalmoscopy (CSLO):
A. uses low-coherence light to produce high-resolution cross-sectional images of the retina
B.employs a laser beam to create detailed images of the retina
Which functional test measures the electrical responses of the visual system to visual stimuli, providing information about visual pathway integrity?
A. Optical coherence tomography (OCT)
B. Confocal scanning laser ophthalmoscopy (CSLO)
C. Visually evoked potentials (VEP)
D. Optokinetic response (OKR)
c
Which functional test assesses a person’s ability to distinguish objects or letters under different levels of contrast?
A. Optical coherence tomography (OCT)
B. Confocal scanning laser ophthalmoscopy (CSLO)
C. High- and low-contrast vision
D. Optokinetic response (OKR)
c
Which functional test measures involuntary eye movements in response to moving visual stimuli?
A. Optical coherence tomography (OCT)
B. Confocal scanning laser ophthalmoscopy (CSLO)
C. Visually evoked potentials (VEP)
D. Optokinetic response (OKR)
d
How do we evaluate if we can include an OCT scan?
O (obvious problems)
S (signal strength above 1s)
C (correctly centered)
A (algorithm failure)- layer segmentation
R (retinal pathology )- cysts, infection, glaucoma
I (illumination)- retinal structures visible
B (beam placement)
OCT advantages &limiitations
- quantitative assessment of retinal pathology (retinal neurodegeneration)
- non- invasive
- no functional outcome
- cannot distinguish cause of pathology
CSLO
a. allows the visualization of fine structural details (detailed images of specific layers within the retina)
b. does not allow the visualization of fine structural details (detailed images of specific layers within the retina)
