Abstract

Purpose: To investigate the impact of stereopsis on vision-related quality of life and general health status of the elderly. Methods: A quota of 200 subjects aged 65 years or older and had their households registered in Guando district was recruited for a general physical examination including ophthalmic evaluation. A structured questionnaire consisting of seven vision-specific items as well as 36-item short-form survey of the Medical Outcomes Study (SF-36) was administered. Stereoscopic level was divided into three groups: no stereopsis, gross stereopsis, and fine stereopsis. Fisher's exact test was used to detect any difference in subjective visual functioning and Mann-Whitney U test was used for analyses of SF-36 scores. Results: A total of 187 volunteers were recruited and 150 were analysed for stereoscopic levels. There was no significant difference in vision-specific difficulty among the three stereoscopic groups. For SF-36, having no stereopsis scored significantly less than having gross (P = 0.005) and fine (P<0.0001) stereopsis in the vitality/energy dimension. General health perception dimension fared significantly lower in the group with no stereopsis compared to the fine stereoscopic group (P = 0.01). In multivariate analysis, having fine stereopsis scored significantly higher in the energy/vitality dimension than having no stereopsis (P = 0.02). On the other hand, visual impairment imposed significant adverse effect on five vision-specific items and had no significant relationship with the eight dimensions of SF-36. Conclusions: Defective stereopsis in the elderly imposes no significant adverse effect on vision-related quality of life. However, subjects may feel more exhausted in accomplishing their usual tasks.
