To measure changes in anterior chamber structure before and after exercise in healthy individuals using anterior segment optical coherence tomography (ASOCT).
Thirty-two healthy young individuals performed jogging for 20 min. Eye blinking rate was recorded during rest and exercise. The anterior chamber angle (ACA), angle opening distance at 500 μm from the scleral spur (AOD500), trabecular-iris space area at 500 μm from the scleral spur (TISA500), iris concavity (IC), iris concavity ratio (CR), iris thickness at 750 μm from the scleral spur (IT750), anterior chamber depth (ACD), anterior chamber width (ACW), pupil diameter (PD), intraocular pressure (IOP), blood pressure (BP) and heart rate (HR) were recorded before and after exercise. Anterior chamber angle (ACA), AOD500, TISA500, IC, IT750, ACD, ACW and PD were measured with ASOCT.
Compared with rest, the blinking rate during exercise did not change significantly (13.04 ± 5.80 versus 13.52 ± 5.87 blinks/min, p = 0.645). The average IOP (15.4 ± 2.4 versus 12.4 ± 2.1 mmHg), ACA (35.96 ± 11.35 versus 40.25 ± 12.64 degrees), AOD500 (0.800 ± 0.348 versus 0.942 ± 0.387 mm), TISA500 (0.308 ± 0.155 versus 0.374 ± 0.193 mm ), IC (-0.078 ± 0.148 versus -0.153 ± 0.159 mm) and CR (-0.027 ± 0.050 versus -0.054 ± 0.056) changed significantly (all p < 0.001), while the average IT750 (0.463 ± 0.084 versus 0.465 ± 0.086 mm; p = 0.492), ACD (3.171 ± 0.229 versus 3.175 ± 0.238 mm; p = 0.543) and ACW (11.768 ± 0.377 versus 11.755 ± 0.378 mm; p = 0.122) showed no significant change after exercise.
The blinking rate did not change significantly during exercise, while ACA, AOD500 and TISA500 increased after exercise. Exercise also induced or increased IC. These changes in anterior chamber structure were only associated with exercise, but not with the postexercise change in PD or IOP.
使用眼前节光学相干断层扫描（ASOCT）测量健康个体运动前后前房结构的变化。
32 名健康的年轻人进行了 20 分钟的慢跑。在休息和运动期间记录眨眼率。测量前房角（ACA）、巩膜突 500μm 处的房角开口距离（AOD500）、巩膜突 500μm 处的小梁虹膜空间面积（TISA500）、虹膜凹陷（IC）、虹膜凹陷比（CR）、巩膜突 750μm 处的虹膜厚度（IT750）、前房深度（ACD）、前房宽度（ACW）、瞳孔直径（PD）、眼压（IOP）、血压（BP）和心率（HR）。使用 ASOCT 测量前房角（ACA）、AOD500、TISA500、IC、IT750、ACD、ACW 和 PD。
与休息时相比，运动时的眨眼率无明显变化（13.04±5.80 次/分比 13.52±5.87 次/分，p=0.645）。平均 IOP（15.4±2.4 毫米汞柱比 12.4±2.1 毫米汞柱）、ACA（35.96±11.35 度比 40.25±12.64 度）、AOD500（0.800±0.348 毫米比 0.942±0.387 毫米）、TISA500（0.308±0.155 毫米比 0.374±0.193 毫米）、IC（-0.078±0.148 毫米比-0.153±0.159 毫米）和 CR（-0.027±0.050 毫米比-0.054±0.056 毫米）变化明显（均 p<0.001），而平均 IT750（0.463±0.084 毫米比 0.465±0.086 毫米，p=0.492）、ACD（3.171±0.229 毫米比 3.175±0.238 毫米，p=0.543）和 ACW（11.768±0.377 毫米比 11.755±0.378 毫米，p=0.122）在运动后无明显变化。
运动时眨眼率无明显变化，而 ACA、AOD500 和 TISA500 在运动后增加。运动还引起或增加了 IC。这些前房结构的变化仅与运动有关，与运动后 PD 或 IOP 的变化无关。
