Aims: One of the factors that reduce the quality of life in many aspects is the blindness, affecting daily activities of the blind persons. The veterans’ dependence might face them with many difficulties in daily activities. The aim of this study was to investigate the instrumental activities of daily life (IADL) in veterans with monocular  blindness.

Instrument & Methods: In the descriptive cross-sectional study, 1371 veterans with monocular  blindness were studied in 2015. The subject were selected via census method from 15 provinces. Data was collected using a demographic form and the IADL scale. Data was analyzed by SPSS 23 software using descriptive statistic and Chi-square and Pearson correlation coefficient tests.

Findings: Mean score of IADL in the monocular -blinded veterans was 11.9±3.8. Washing and ironing the clothes (61.6%), household chores (58.9%), and food preparation (49.3%) were the highest dependence items of the veterans, respectively. Phone utilization (17.4%) and transport (24.6%) were the lowest dependence items of the veterans, respectively. About two-thirds of the veterans (62.0%) were independent at IADL. Age, injury age, injury percentage, educational level, occupation, and injuries other than the monocular  blindness were significantly correlated with the scores of IADL (p<0.05).

Conclusion: Monocular  blindness does not much reduce the instrumental activities of daily life in persons. Nevertheless, about one-third of the monocular-blinded veterans are dependent to other persons at instrumental activities of daily life.
