Article Review – How does head tilt affect RNFL measurement on SPECTRALIS SD-OCT in comparison to Cirrus SD-OCT

For retinal nerve fiber layer thickness (RNFLT) measurements, the correct anatomic alignment of scans according to the fovea-to-Bruch’s membrane opening center is critical. Head tilt and natural eye movement can cause scan alignment artifacts that may lead to a negative impact on the diagnostic accuracy and can also significantly impact follow-up scans.
A study compared the misclassification of RNFLT measurements due to head tilt on both a Heidelberg Engineering SPECTRALIS® SD-OCT and a Zeiss Cirrus® SD-OCT.
Find out how head tilt and eye movement can affect retinal nerve fiber layer thickness measurements depending on the imaging system used.
