The study documents the ability of Elisar-Fast to successfully assess visual field in patients with glaucoma.
To compare 2 fast threshold strategies of visual field assessment: SITA-Fast (SF; Humphrey field analyser) and Elisar-Fast (EF; advanced vision analyser) in patients with glaucoma.
In this cross-sectional observational study, of total 192 subjects, 138 subjects (150 eyes, 80 glaucoma subjects [91 eyes] and 58 healthy controls [59 eyes]) were analysed and included. Each subject underwent 24-2 EF and SF in randomized order with a minimum time interval of 1 hour between tests.
Mean test-time, pointwise and sectoral sensitivity, significance of values of mean sensitivity (MS) and global indices (mean deviation [MD] and pattern SD [PSD]) and their correlation.
The mean test-time was 2.59±0.25 and 3.38±0.28 minutes ( P = 0.001) with SF and EF, respectively. Correlation coefficient for pointwise threshold values correlated strongly for both devices (range, 0.70-0.92). The intraclass correlation value of ≥0.8 was observed across all sectors, indicating good reliability. Bland-Altman plot denoted 95% of the data for MS values within limit of agreement. The intraclass correlation values for overall MS, MD, and PSD were 0.916, 0.913, and 0.872, respectively, indicating good reliability. High degree of correlation was observed for MD (r=0.912, P =0.00) and PSD values (r=0.732, P =0.00). Comparison of values indicated a difference of 1.09 dB for MD and 0.06 dB for PSD between both strategies.
A high degree of correlation existed between the global indices and pointwise threshold values. The study documents the ability of EF to successfully assess visual field in patients with glaucoma.
该研究记录了Elisar-Fast成功评估青光眼患者视野的能力。
比较青光眼患者视野评估的两种快速阈值策略：SITA-Fast（SF；Humphrey视野分析仪）和Elisar-Fast（EF；先进视觉分析仪）。
在这项横断面观察性研究中，总共192名受试者中，分析并纳入了138名受试者（150只眼睛，80名青光眼受试者[91只眼睛]和58名健康对照者[59只眼睛]）。每个受试者以随机顺序接受24-2 EF和SF检查，两次检查之间的最短时间间隔为1小时。
平均检查时间、逐点和扇形敏感度、平均敏感度（MS）值和整体指标（平均偏差[MD]和模式标准差[PSD]）值的显著性及其相关性。
SF和EF的平均检查时间分别为2.59±0.25分钟和3.38±0.28分钟（P = 0.001）。两种设备的逐点阈值相关系数都很强（范围为0.70 - 0.92）。在所有扇形区域内观察到类内相关值≥0.8，表明可靠性良好。Bland-Altman图显示95%的MS值数据在一致性界限内。整体MS、MD和PSD的类内相关值分别为0.916、0.913和0.872，表明可靠性良好。MD（r = 0.912，P = 0.00）和PSD值（r = 0.732，P = 0.00）观察到高度相关性。两种策略之间MD值差异为1.09 dB，PSD值差异为0.06 dB。
整体指标与逐点阈值之间存在高度相关性。该研究记录了EF成功评估青光眼患者视野的能力。
