英文摘要 | Visual-training methods in management of myopia are suggested as possibly leading to normal vision or an improvement in the refractive state. The purpose of this work was to investigate the hypothesis that a Qi-Qong ocular exercise improves visual function by training the accommodation bias. Variations of pupil size, accommodative amplitude, latency and speed of accommodative response and accommodative adaptation were evaluated objectively. The accommodative state was monitored with an objective infrared refractometer (Nidek AA-2000). Subjects were divided into two groups: experimental (n = 9), and control (n = 8). Subjects of the experimental group undertook the Qi-Qong ocular exercise for at least three years, and were able to perform the exercise smoothly and gently. Subjects of the control group had no knowledge of the Qi-Qong ocular exercise, but were given the same testing procedures as the experimental group. Results showed that Qi-Qong ocular exercise can improve the accommodative amplitude and accelerate the accommodative response slightly, but there was no effect on the latency of accommodative response. Furthermore, the level of accommodative adaptation was elevated, and the pupil became slight miotic. Therefore, the mechanism of visual improvement may undergo a great accommodative adaptation and produce a pinhole effect by miosis of the pupil. Methods of visual training can produce a false image of visual improvement from an enhanced parasympathetic response to a task, but this effect may be a factor that induces progression of myopia. |
