Visual Acuity and Intraocular Pressure Among Adults Visiting Health Care Center in Seoul

ABSTRACT

The visual acuity and intraocular pressure were measured and analyzed in 1641 healthy adults visiting AMC health care center. The visual acuity was measured irrespective of wearing glasses and contact lenses with autoacuitometer and we defined this visual acuity as everyday vision. The average everyday vision of better eye was 1.10 in males and 0.96 in females[converted with Han chart0.95, 0.85; converted with Jin chart 0.89, 0.78] between 20 and 69 years old. The average everyday vision in males was better than that of females[p<0.01]. The everyday vision was decreased in older subjects. The everyday vision of the subjects under 44 years of age was better than that of over 45 years of age[p<0.01]. The linear equation of the everyday vision according to age was Y=-0.0049X 1.30 in males[R=-0.77], Y=-0.0112X 1.43 in females[R=-0.88][Xage, Yvisual acuity, Rcorrelation coefficient]. In classification according to occupation, the visual acuity of housewives was low 0.89, but when matched to age &sex it was statistically insignificant. The average intraocular pressure was 13.25+/-2.57 mmHg in males, 12.85+/-2.45 mmHg in females. The IOP of the subjects under 44 years of age was not different from those over 45 years of age[male p=0.31, female p=0.20]. The number of subjects higher than 21 mmHg in intraocular pressure was 21[0.64%].
