OBJECTIVE: To observe the influences of 21-day head down tilt (HDT) bed rest on intraocular pressure (IOP), visual field, and near vision in humans, and to study the countermeasure of Chinese herbs against weightlessness. METHODS: Ten subjects were randomly divided into a control group and a Chinese herb group; 6° HDT was used to simulate weightlessness. IOP, near vision and vision field were measured before, during and after bed rest in both groups. RESULTS: IOP and near vision showed a wave-like decrease change during bed rest, and there exists a certain coherence between them. Visual field showed no obvious changes. The taking Chinese herbs antagonized the decrease of IOP and near vision during various phases of bed rest. CONCLUSIONS: Bed rest could lead to the decrease of IOP and near vision. The taking Chinese herbs antagonized the negative influences of bed rest on visual function. LA: Chinese
