To evaluate whether the order of eye testing affects the mean deviation (MD) or the test reliability of visual field testing using the Swedish Interactive Threshold Algorithm (SITA) standard 24-2.
Consecutive patients with manifest or suspect glaucoma with 2 prior sets of SITA standard 24-2 test results performed on the right eye first were enrolled. A subsequent test was performed on the left eye first. For each eye, the MD and the test reliability indexes (> or = 20%) were compared among the 3 successive examinations.
Forty-seven patients (29 women and 18 men; mean +/- SD age, 70.6 +/- 11.9 years) were enrolled. The MD +/- SD was -5.83 +/- 5.43 dB OD and -5.46 +/- 4.86 dB OS. There was no statistically significant difference in the MD or the test reliability among the 3 test results for either eye. Fixation loss was responsible for the unreliable fields in almost all cases.
Among this cohort of patients experienced with automated perimetry in a glaucoma subspecialty practice, changing the order of eye testing using the SITA standard 24-2 did not have a significant effect on the MD or the test reliability. Intereye fatigue may not be clinically significant with this algorithm. Fixation loss remains a problem with the use of this algorithm.
使用瑞典交互式阈值算法（SITA）标准24-2评估眼部检查顺序是否会影响视野检查的平均偏差（MD）或检查可靠性。
纳入连续的患有显性或疑似青光眼且右眼先进行过2组SITA标准24-2检查结果的患者。随后先对左眼进行检查。对每只眼睛，比较3次连续检查中的MD和检查可靠性指标（≥20%）。
纳入47例患者（29例女性和18例男性；平均±标准差年龄，70.6±11.9岁）。右眼的MD±标准差为-5.83±5.43 dB，左眼为-5.46±4.86 dB。两只眼睛的3次检查结果在MD或检查可靠性方面均无统计学显著差异。几乎在所有病例中，固视丢失导致视野检查不可靠。
在青光眼专科实践中进行自动视野检查的这组患者中，使用SITA标准24-2改变眼部检查顺序对MD或检查可靠性没有显著影响。使用该算法时，双眼间疲劳可能在临床上不显著。使用该算法时，固视丢失仍然是一个问题。
