7Test-Retest Reliability of Functional Magnetic Resonance Imaging Activation for a Vergence Eye Movement Task显示文摘Vergence eye movements are the inward and outward rotation of the eyes responsible for binocular coordination.While studies have mapped and investigated the neural substrates of vergence,it is not well understood whether vergence eye movements evoke the blood oxygen level-dependent signal reliably in separate experimental visits.The test-retest reliability of stimulus-induced vergence eye movement tasks during a functional magnetic resonance imaging(fMRI)experiment is important for future randomized clinical trials(RCTs).In this study,we established region of interest(ROI)masks for the vergence neural circuit.Twenty-seven binocularly normal young adults participated in two functional imaging sessions measured on different days on the same 3 T Siemens scanner.The fMRI experiments used a block design of sustained visual fixation and rest blocks interleaved between task blocks that stimulated eight or four vergence eye movements.The test-retest reliability of task-activation was assessed using the intraclass correlation coefficient(ICC),and that of spatial extent was assessed using the Dice coefficient.Functional activation during the vergence eye movement task of eight movements compared to rest was repeatable within the primary visual cortex(ICC=0.8),parietal eye fields(ICC=0.6),supplementary eye field(ICC=0.5),frontal eye fields(ICC=0.5),and oculomotor vermis(ICC=0.6).The results demonstrate significant test-retest reliability in the ROIs of the vergence neural substrates for functional activation magnitude and spatial extent using the stimulus protocol of a task block stimulating eight vergence eye movements compared to sustained fixation.These ROIs can be used in future longitudinal RCTs to study patient populations with vergence dysfunctions.Cristian Morales Suril Gohel Xiaobo Li Mitchell Scheiman Bharat B.Biswal Elio M.Santos Chang Yaramothu Tara L.Alvarez 2020Neuroscience Bulletin2020,36,5:1

10白内障手术相关的不等像及其对术后双眼视觉的影响显示文摘目的:探讨双眼白内障术后不等像的变化,并分析不等像对术后双眼视觉状态的影响。方法:前瞻性临床研究。2019年1—11月于萨鲁斯大学宾夕法尼亚视光学院和LewisLASIK眼科诊所招募拟接受双眼白内障手术的患者(≥50岁)73例。所有受检者在第1眼手术前接受不等像检查,第2眼手术后接受不等像检查和综合双眼视检查。综合双眼视检查方案包括立体视、眼位、融像性聚散、聚散灵活度及集合近点检查等。根据双眼视检查结果确定受检者的双眼视觉状态(正常双眼视或双眼视异常)。采用McNemar卡方检验比较手术前、后有临床意义的不等像比例(≥3%);Spearman检验分析不等像与屈光参差、双眼人工晶状体(IOL)度数差值及立体视之间的相关性;Logistic回归分析不等像对术后双眼视觉状态的影响;受试者工作特征(ROC)曲线确定能预测术后是否存在双眼视异常的不等像临界值。结果:术后平均随访时间为2个月。最终纳入51例受检者,其中13例(25%)在术后被诊断为非斜视性双眼视异常,主要为集合不足11例(22%)。术后有临床意义的不等像比例较术前差异无统计学意义(χ^(2)=1.14,P=0.286)。术前、术后及术源性不等像与屈光参差、双眼IOL度数差值及立体视均无相关性。Logistic回归分析显示,术后的双眼视异常与术前(OR=1.46,P=0.047)、术后(OR=1.67,P=0.031)及术源性(OR=1.48,P=0.021)不等像之间均存在相关性。ROC曲线分析显示,术源性不等像显示出最佳的曲线下面积(AUC),其AUC值为0.74,术源性不等像>2.4%时,其预测术后双眼视异常的敏感性和特异性最佳,分别为80.6%和65.0%。术前和术后的不等像AUC值分别为0.68、0.66,分别取临界值3.3%和2.9%时,预测的敏感性和特异性最佳。结论:双眼白内障手术并不明显改变不等像。然而,双眼白内障手术群体的不等像可作为预测因子,用来预测术后发生双眼视异常的风险。谭青青 廖萱 兰长骏 James Lewis Mitchell Scheiman 2022中华眼视光学与视觉科学杂志2022,24,11:0
