목적: IOL Master 700으로 측정한 동공 크기와 각막곡률을, 비디오 동공 크기 측정기와 자동각막곡률검사기로 측정한 값과 비교하여 유용성을 평가하고자 하였다. 대상과 방법: 소아 50명, 100안을 대상으로 IOL Master 700과 비디오 동공 크기 측정기로 동공 크기를 측정하고, IOL Master 700과 자동각막곡률검사기로 수평 각막곡률과 수직 각막곡률을 측정하였다. 측정 방법들의 비교는 paired t-test와 피어슨 상관관계 분석을 이용하였고, 측정 방법 간의 일치도는 Bland Altman plot와 급내상관계수를 통해 나타내었다. 결과: 동공 크기는 IOL Master 700과 비디오 동공 크기 측정기로 측정한 값이 통계적으로 유의한 차이가 없었다(p>0.05). 수직 각막곡률 또한 IOL Master 700과 자동각막곡률검사기로 측정한 값이 유의한 차이가 없었다(p>0.05). 반면 수평 각막곡률은 IOL Master 700과 자동각막곡률검사기로 측정한 값이 유의한 차이가 있었으며, IOL Master 700으로 측정한 값이 평균 우안 0.105 diopters (D), 좌안 0.130 D만큼 더 컸다(p<0.05). 결론: 협조도가 떨어지는 소아에서, IOL Master 700은 동공 크기와 각막곡률을 동시에 측정할 수 있는 신뢰할 수 있는 유용한 검사 기구가 될 수 있을 것으로 보인다.
Abstract
Purpose: To compare IOL Master 700 with autokeratometer and video pupillometer in measurement of pupil diameter and corneal curvature. Methods: Pupil diameter were measured with IOL Master 700 and video pupilometer, horizontal keratometry and vertical keratometry were measured with IOL Master 700 and autokeratometer in 100 eyes of 50 children. Paired t-test and Pearson's correlation analysis were used to compare the differences among the devices. Agreement between measurement was analyzed using Bland Altman plot and intraclass correlation coefficient. Results: Comparing IOL Master 700 and video pupilometer for pupil diameter, there was no significant difference (p > 0.05). There was also no significant difference between IOL Master 700 and autokeratometer in measurement of vertical keratometry (p > 0.05). However, regarding horizontal keratometry there was significant difference between IOL Master 700 and autokeratometer, horizontal keratometry measured with IOL Master 700 was steeper than with auto keratometer, +0.105 diopters (D) in right eye and +0.130 D in left eye (p < 0.05). Conclusions: There was good agreement between IOL Master 700 and comparator instruments in regards to pupil diameter and corneal curvature. IOL Master 700 can be helpful in uncooperative children for measuring pupil diameter and corneal curvature at the same time.
