Abstract

Background: Visual acuity has been shown to correlate with foveal threshold as determined by automated perimetry. Although automated perimetry with size V stimulus is commonly used in neuro-ophthalmology practice, the relationship between the visual acuity and the foveal threshold with this larger stimulus is not well known.

Methods: Retrospective study of patients who had undergone neuro-ophthalmology evaluation and visual field testing with automated perimetry using size V stimulus. Healthy controls were also recruited. Using visual acuity and foveal threshold, Pearson correlation coefficients were calculated, and basic foveal threshold statistics were stratified by visual acuity. Prediction intervals for visual acuities by various foveal threshold were also calculated.

Results: A total of 106 unique eyes were included. The final Pearson correlation coefficient between visual acuities was -0.795 for the right eye and -0.578 for the left eye, with a pooled correlation coefficient of -0.751 ( P < 0.001). A foveal threshold of at least 34 dB was present in 94.4% of eyes with 20/20 visual acuity, and a foveal threshold of greater than 35 dB was not observed in eyes with visual acuity of 20/40 or worse.

Conclusions: Foveal threshold as determined by automated perimetry using size V stimulus has moderate-to-strong correlation with visual acuity in patients undergoing neuro-ophthalmology evaluation.

使用 V 尺寸刺激的自动验光法测定视力和眼窝阈值之间的相关性
背景:研究表明,视敏度与自动周边测定法确定的眼窝阈值相关。虽然在神经眼科临床中常用 V 型刺激物进行自动周边测量,但这种较大刺激物的视敏度与眼窝阈值之间的关系尚不十分清楚:方法:对接受过神经眼科评估和视野测试的患者进行回顾性研究。同时还招募了健康对照组。利用视敏度和眼窝阈值计算皮尔逊相关系数,并根据视敏度对基本眼窝阈值统计数据进行分层。此外,还计算了不同眼窝阈值对视力的预测区间:共纳入 106 只独特的眼睛。右眼和左眼视力之间的最终皮尔逊相关系数分别为-0.795和-0.578,汇总相关系数为-0.751(P < 0.001)。94.4%视力为20/20的眼睛的眼窝阈值至少为34 dB,视力为20/40或更差的眼睛的眼窝阈值不超过35 dB:结论:在接受神经眼科评估的患者中,使用 V 型刺激物进行自动视力测定所确定的眼窝阈值与视力具有中度到高度的相关性。
