AIM
To compare the Sbisa bar (Bagolini filter bar) with neutral density filters (NDF) in quantifying relative afferent pupillary defects (RAPD).
METHODS
11 patients with a RAPD were graded and a neutral density filter bar was used to quantify the RAPD. This was repeated using the Sbisa bar. The Sbisa bar (Bagolini filter bar) is used by orthoptists to quantify density of suppression in amblyopia and is of a similar construct to NDFs. Before this clinical part of the study the luminance for each filter was measured, which enabled a direct comparison to be made.
RESULTS
In the analysis of patients with RAPD a high correlation was found when comparing the Sbisa and NDF bars r = 0.95. This was statistically significant (p = <0.001). Correlation was also high when the luminance values for the filters were substituted for the clinical readings (r = 0.92; p=<0.001).
CONCLUSION
The Sbisa bar is a comparable instrument to the NDF bar in measuring RAPD. Its availability in the clinical situation makes it a practical choice.
目的
比较Sbisa棒（巴戈利尼滤光棒）与中性密度滤光片（NDF）在定量相对性传入性瞳孔障碍（RAPD）方面的效果。
方法
对11例患有RAPD的患者进行分级，并用中性密度滤光棒对RAPD进行定量。使用Sbisa棒重复此操作。Sbisa棒（巴戈利尼滤光棒）被斜视矫正师用于定量弱视中的抑制密度，其结构与NDF相似。在本研究的临床部分之前，测量了每个滤光片的亮度，以便进行直接比较。
结果
在对患有RAPD的患者进行分析时，比较Sbisa棒和NDF棒时发现高度相关性，r = 0.95。这具有统计学意义（p = <0.001）。当用滤光片的亮度值替代临床读数时，相关性也很高（r = 0.92；p = <0.001）。
结论
在测量RAPD方面，Sbisa棒是一种与NDF棒相当的仪器。它在临床环境中的可用性使其成为一个实际的选择。
