PURPOSE/METHODS: The effect of exercise on the iris contour was investigated with ultrasound biomicroscopy in two patients with pigmentary glaucoma.
RESULTS/CONCLUSION: Ten minutes of bicycle exercise strikingly increased the iris concavity. After Nd:YAG laser iridotomy the iris remained plane after a repeated exercise test. We believe that exercise increased the ocular pulse, which augmented cyclic aqueous movements through the pupil. Combined with a reverse pupillary block, the resulting intermittent excessive iris concavity caused pigment dispersion.
目的/方法：采用超声生物显微镜检查，对两名色素性青光眼患者进行运动对虹膜形态影响的研究。
结果/结论：十分钟的自行车运动显著增加了虹膜凹陷度。Nd:YAG激光虹膜切开术后，再次进行运动试验时虹膜保持平坦。我们认为运动增加了眼内压，从而增强了房水通过瞳孔的循环运动。再加上反向瞳孔阻滞，由此产生的间歇性过度虹膜凹陷导致色素播散。
