Abstract. Purpose:To report the relationship between visual acuity and intelligence quotient(IQ)in senile persons staying in institutions. Cases and Method:This study was made on 18 persons who were seen as house visits. The series comprised 2 males and 16 females. The age ranged from 73 to 98 years,average 85 years. Each person was examined for near visual acuity(VA)and IQ. Fifteen persons were reexamined 18 months later. Results:IQ was over 11 years in 6 persons(33%),between 2 and 11 years in 9(50%),and below 2 years in 3(17%). When examined 18 months later,IQ improved in 4,remained in 2 and deteriorated in 1 in 7 persons with initial IQ between 2 and 11 years. Improvement in IQ was frequent in those with improved VA. Three persons showed unchanged in IQ when initial IQ was below 2 years. Conclusion:Improvement in IQ and VA ran parallel when caused by cerebral or mental disorders.
