Outline of Final Research Achievements

The subjects of the study were inpatients with schizophrenia. We collected data on PANSS, MMSE, the Japanese version of NEI VFQ-25, visual acuity measurement using an automatic visual acuity meter, and SE value using an autorefkeratometer. Our results showed no significant correlation between visual acuity (logMAR), SE value, PANSS, and MMSE. Multiple regression analysis also showed no significant difference, but in the short-term morbidity group (Group A), unlike in the long-term morbidity group (Group B), SE values were negatively associated with the total score of PANSS. In addition, negative symptoms tend to strengthen this relationship. Regarding VFQ-25, in Group A, the mean score of logMAR was positively associated with the score of VFQ-25, but in group B, it was negatively associated.

Academic Significance and Societal Importance of the Research Achievements

本研究において、統計的に有意な結果は得られなかったが、統合失調症入院患者において罹患期間が短い患者ほど視力が精神状態に影響を与えている可能性があり、またQOLにおいても罹患期間が短い患者ほどQOLが低いと感じている傾向がある事が示唆された。これらは、統合失調症発症初期から視力や視機能が精神状態やQOLに影響を与えている可能性があるため、統合失調症の治療やケアと同様に、見過ごされがちではあるが視機能に対する治療やケアも行なっていくことで、患者の精神状態の改善に寄与できる可能性があると考える。
