Using a computer-assisted infrared optometer we studied the long-term accommodative behavior in a 31-year-old man whose eyes had been accidentally exposed to diisopropyl fluorophosphate vapor. The initial examination revealed a delay of accommodative relaxation in both quasi-static and dynamic measurements, which recovered within one month, and a characteristic behavior in dark focus of accommodation, that is, a repetition of prominent myopic shift followed by rapid relaxation. This abnormal dark focus of accommodation appeared more marked after the subject was forced to fixate on a near target at a distance of three diopters. These abnormalities in dark focus of accommodation were fairly reduced three months later, but myopic shift was detected even 13 months later. The findings suggest a close association between myopic shift in the dark focus of accommodation and parasympathetic excitation.
我们使用计算机辅助红外验光仪，对一名31岁男性的长期调节行为进行了研究，该男子的眼睛意外暴露于氟磷酸二异丙酯蒸汽中。初始检查发现，在准静态和动态测量中，调节松弛均有延迟，延迟在一个月内恢复，且调节暗焦点存在特征性行为，即反复出现明显的近视性偏移，随后快速松弛。在受试者被迫注视三屈光度距离的近目标后，这种异常的调节暗焦点显得更为明显。三个月后，调节暗焦点的这些异常情况明显减轻，但即使在13个月后仍检测到近视性偏移。研究结果表明，调节暗焦点的近视性偏移与副交感神经兴奋之间存在密切关联。
