We investigated changes of intraocular pressure (IOP) according to eye gaze. IOP was significantly elevated in adduction, abduction, and supraduction. However, there was no significant difference between glaucoma and control groups.
We assessed changes in IOP according to eye gaze and identified their correlations with various risk factors of glaucoma.
In this prospective observational study that included 56 glaucoma patients and 34 healthy participants, we measured IOP in the primary position with a Goldmann applanation tonometry and rebound tonometer. Then, this IOP was measured in abduction, adduction, supraduction using a rebound tonometer. IOP changes according to eye gaze were measured based on the baseline IOP, and IOP changes between glaucoma and the control groups were compared. Correlations between IOP changes and risk factors of glaucoma were evaluated.
The baseline IOP was not significantly different between glaucoma and the control groups. Compared with the IOP in the primary position, a significant increase in IOP was 2.3±2.7 mm Hg during abduction (P<0.0001), 0.7±2.7 mm Hg during adduction (P<0.0001), and 1.2±2.8 mm Hg during supraduction (P<0.0001). However, there was no significant difference in the amount of IOP elevation or the ratio of IOP change between glaucoma and the control groups in all gazes. The baseline IOP measured by Goldmann applanation tonometry and IOP changes according to eye gaze showed a significant negative correlation in all gazes.
IOP was significantly elevated in adduction, abduction, and supraduction than in the primary position in both the normal and glaucoma groups. However, there was no significant difference of IOP changes between glaucoma and normal groups.
我们研究了根据眼球注视方向眼压（IOP）的变化。内转、外转和上转时眼压显著升高。然而，青光眼组和对照组之间没有显著差异。
我们评估了根据眼球注视方向眼压的变化，并确定其与青光眼各种危险因素的相关性。
在这项前瞻性观察研究中，纳入了56例青光眼患者和34名健康参与者，我们使用Goldmann压平眼压计和回弹眼压计在第一眼位测量眼压。然后，使用回弹眼压计在内转、外转、上转时测量眼压。根据基线眼压测量根据眼球注视方向的眼压变化，并比较青光眼组和对照组之间的眼压变化。评估眼压变化与青光眼危险因素之间的相关性。
青光眼组和对照组的基线眼压没有显著差异。与第一眼位的眼压相比，外转时眼压显著升高2.3±2.7 mmHg（P<0.0001），内转时升高0.7±2.7 mmHg（P<0.0001），上转时升高1.2±2.8 mmHg（P<0.0001）。然而，在所有注视方向上，青光眼组和对照组的眼压升高幅度或眼压变化率没有显著差异。Goldmann压平眼压计测量的基线眼压与根据眼球注视方向的眼压变化在所有注视方向上均呈显著负相关。
正常组和青光眼组内转、外转和上转时的眼压均比第一眼位显著升高。然而，青光眼组和正常组之间的眼压变化没有显著差异。
