Background: Visual world experiences have an important role in the development of cognitive functions of
brain. Exact and fast visual information is critical for brain cognitive functions.
Pupose: The aim of this study is comparison of clinical memory function of blinds veteran with normal sighted
matched person.
Material and Methods: In this cross-sectional study, we compare 137 blinds and 124 sighted people in clinical
memory performance. The test was Wechsler Adult Intelligence Scales-Revised (WAIS-R). Independent T
Test was used to comparing blinds with sighted.
Results: Age of blind group was 41.75±7.69 and in sighted group was 41.86 ±8.14. Findings show significant
difference between two groups in sub scales and total scores of Wechsler. (P <0.000) Result shows no
significant difference in retrieval subscale. (P=0.054)
Discussion: Based on this study blinds have lower performance in memory functions. This finding can show
correlation between clinical memory performance and visual information.
