摘要

Purpose: To evaluate stereopsis in patients with schizophrenia in Taiwan
Methods: 130 patients with schizophrenia and 80 healthy volunteer subjects (at various ages) were enrolled into our study. All experiments were designed to compare the results of the stereopsis. In experiment 1, we compared the normal subjects and outpatients with schizophrenia. Experiment 2 was designed to compare stereopsis between male and female outpatients. Experiment 3 was conducted to determine the differentces between ages from 20-29/30-39/40-49/50-59/60-69 among patients with schizophrenia. In experiment 4, we analyzed the stereopsis between outpatients and inpatients. The method of Timtus (cycles) was used to evaluate the results of stereopsis (ranging from 800 to 40 msec).
Result: According to the analysis conducted in experiment 1: the stereopsis in patients with schizophrenia was worse than in normal subjects (140.5±3.99 vs 43.5 ±4.6 msec; p＜0.005), the stereopsis of male patients was worse than female ones (271.0±92.6 vs 120.5±3.7 msec; p＜0.005) in experiment 2. In experiment 3, the older the patient, the worse the stereopsis was (56.7±28.3 vs 70.9±39.9 vs 205.7±87.5 vs 240.8±76.4 vs 300.6±41.4 msec; p＜0.005). The poor stereopsis of the inpatients was noted compared with outpatients (140.2±3.8.5 vs 720.4±56.6 msec; p＜0.005) in experiment 4.
Conclusion: The results clearly indicated the stereopsis of patients with schizophrenia is worse than in normal subjects, in particular male and older patients. Because schizophrenia is a kind of chronic disease, patients all require long-term care. Because of the poor stereopsis, they cannot exactly analyze the location of objects. As a result, we should pay attention to the injuries occurring by accident, such as from walking unsteadily or falling down.
