BACKGROUND
Qualitative description of the optic disc has clinical value, but optical coherence tomography (OCT) has provided the ability to quantify retinal nerve fiber layer (RNFL) thickness.
METHODS
We asked three neuro-ophthalmologists of at least 20 years' experience to estimate the average OCT RNFL thickness of 37 eyes based on fundus photos.
RESULTS
The overall correlation coefficient for RNFL thickness estimation variance between two physicians and between physician and OCT was 0.53. The likelihood that the RNFL thickness estimation between physicians, or between physician and OCT, was within 10 μm of each other was 47%-62%. All physicians had disparities in RNFL thickness estimation greater than 30 μm.
CONCLUSION
This study provides information on the ability of an experienced neuro-ophthalmologist to estimate the RNFL thickness based on fundus photos.
背景
视盘的定性描述具有临床价值，但光学相干断层扫描（OCT）已具备量化视网膜神经纤维层（RNFL）厚度的能力。
方法
我们邀请了三位具有至少20年经验的神经眼科医生，根据眼底照片估算37只眼睛的平均OCT RNFL厚度。
结果
两位医生之间以及医生与OCT之间RNFL厚度估计差异的总体相关系数为0.53。医生之间或医生与OCT之间RNFL厚度估计彼此相差在10μm以内的可能性为47%-62%。所有医生在RNFL厚度估计上的差异均大于30μm。
结论
本研究提供了关于经验丰富的神经眼科医生根据眼底照片估算RNFL厚度能力的信息。
