Sources of errors in measurement of retinal nerve fiber layer thickness using optical coherence tomography
Background: Optical coherence tomography (OCT)–obtained retinal nerve fiber layer (RNFL) thickness measurements allow for qualitative and quantitative assessment of RNFL thinning in glaucoma. Errors in data acquisition or in software analysis may result in artifacts and erroneous RNFL thickness mea...

| description | Background: Optical coherence tomography (OCT)–obtained retinal nerve fiber layer (RNFL) thickness measurements allow for qualitative and quantitative assessment of RNFL thinning in glaucoma. Errors in data acquisition or in software analysis may result in artifacts and erroneous RNFL thickness measurements that may lead to an inaccurate clinical interpretation. Purpose: This video describes tips to recognize artifacts in RNFL thickness measurement in various OCT printouts. Synopsis: The video presents a series of OCT of optic nerve head printouts with artifacts and useful teaching points to identify the same and its source of error. Highlights: The technician must confirm the quality and accuracy of the acquired data before the patient returns to the physician with the final printout. Recognition of artifacts and identifying its source of error is critical to interpret the data accurately, avoiding erroneous clinical interpretation.
