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.
This video describes tips to recognize artifacts in RNFL thickness measurement in various OCT printouts.
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.
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.
光学相干断层扫描（OCT）获得的视网膜神经纤维层（RNFL）厚度测量可定性和定量评估青光眼的 RNFL 变薄。数据采集或软件分析中的错误可能导致伪影和错误的 RNFL 厚度测量，从而导致不准确的临床解释。
本视频介绍了在各种 OCT 打印输出中识别 RNFL 厚度测量伪影的技巧。
该视频展示了一系列具有伪影的视神经头 OCT 打印输出，以及有用的教学要点，以识别相同的伪影及其误差源。
在将最终打印输出返回给医生之前，技术人员必须确认所获取数据的质量和准确性。识别伪影并确定其误差源对于准确解释数据、避免错误的临床解释至关重要。
