Purpose. To evaluate the short-term effect of standard automated perimetry (SAP) testing on intraocular pressure (IOP) in patients with open-angle glaucoma (OAG). Methods. We tested 45 patients (71 eyes) with OAG that had stable IOP under medical treatment. IOP was measured four times using an iCare rebound tonometer (RBT) immediately before, immediately after, 10 minutes after, and 20 minutes after SAP testing. Logistic regression analyses were performed to determine the relationships among SAP test duration, mean deviation of the SAP result, type of glaucoma medications, patient age, and significant IOP change (exceeding 2 mmHg) from baseline IOP. Results. The mean baseline IOP was 13.29 ± 3.06 mmHg. Although IOP changes immediately and 20 minutes after SAP testing were not statistically significant, the IOP change 10 minutes after SAP testing (-0.57 ± 1.84 mmHg) was statistically significant. However, the changes were within the margin of error of the RBT. Test duration, mean deviation, patient age, and type of glaucoma medications did not have a significant influence on IOP change (all P > 0.14). Conclusions. IOP measured by RBT did not vary significantly after SAP testing in patients with OAG. It may be not necessary to reject IOP measured after SAP testing in patients with OAG.
目的。评估标准自动视野计（SAP）测试对开角型青光眼（OAG）患者眼压（IOP）的短期影响。方法。我们对45例（71只眼）接受药物治疗且眼压稳定的OAG患者进行了测试。在SAP测试前即刻、测试后即刻、测试后10分钟和测试后20分钟，使用iCare回弹眼压计（RBT）测量眼压4次。进行逻辑回归分析以确定SAP测试持续时间、SAP结果的平均偏差、青光眼药物类型、患者年龄以及与基线眼压相比眼压的显著变化（超过2 mmHg）之间的关系。结果。平均基线眼压为13.29±3.06 mmHg。虽然SAP测试后即刻和20分钟时的眼压变化无统计学意义，但SAP测试后10分钟时的眼压变化（-0.57±1.84 mmHg）具有统计学意义。然而，这些变化在RBT的误差范围内。测试持续时间、平均偏差、患者年龄和青光眼药物类型对眼压变化均无显著影响（所有P>0.14）。结论。OAG患者在SAP测试后，通过RBT测量的眼压无显著变化。对于OAG患者，可能没有必要舍弃SAP测试后测量的眼压值。
