Abstract

VISUAL DISTURBANCEs were studied in a national sample of 59678 people (1/1000 of country population) through self-reporting of VISUAL DISTURBANCEs, and through measurement of VISUAL ACUITY and VISUAL FIELD by optometrists in 1/3 of the same sample who were 5 years old or more. The national survey has been undertaken in 1994. It has been designed by Welfare and Rehabilitation University of IRAN, and conducted by Welfare Central Offices in each state, through cluster sampling method (cluster of 15 dwellings).The results show that 32.3% of the country population has a VISUAL ACUITY of equal or less than 20/30 in at least one eye and 23.1% for concurrence in both eyes. Estimate of partial prevalence of VISUAL DISTURBANCE(visual acuity equal or less than 20/30 in both eyes) in all states with respect to Tehran prevalence implies that prevalence of 7 states statistically is higher and of 10 states is less than prevalence of Tehran state (P<0.05).Prevalence of VISUAL FIELD disturbance is 6.3% in both eyes and 9.1 % in at least one eye. Estimate of partial prevalence of this VISUAL DISTURBANCE with respect to prevalence of Tehran state shows that prevalence of 9 states statistically is higher and of 1 state is less than prevalence of Tehran state (P< 0.05). Difference in VISUAL DISTURBANCEs in states could be from different epidemiological patterns ,diffrent rates and quality of health services in states.Aging causes the VISUAL DISTURBANCEs increase, based on both VISUAL ACUITY and VISUAL FIELD data.
