목적: 비접촉 안압계, 리바운드 안압계(IcareⓇ), 토노펜(TONO-PEN AVIAⓇ)으로 측정한 안압을 골드만 압평안압계로 측정한 안압을기준으로 비교하고 임상적 유용성을 고찰한다. 대상과 방법: 정상안 71안을 대상으로 비접촉 안압계, 리바운드 안압계, 토노펜, 골드만 압평안압계로 안압을 측정하고 안압계별 측정값차이를 비교하였다. 결과: 리바운드 안압이 골드만 안압과 가장 높은 일치성을 보였고[ICC 0.811, 95%CI 0.712-0.878], Bland-Altman plot 결과, 비접촉안압계에서 평균 차이값은 가장 적었으나(+0.2 mmHg) 신뢰구간은 가장 넓었고(95%CI; ±5.05 mmHg), 리바운드 안압계는 평균 차이값이 다소 적고(-0.7 mmHg) 변동폭이 가장 좁았다(95%CI; ±3.75 mmHg). 결론: 리바운드 안압계로 측정한 안압은 골드만 압평안압계로 측정한 안압과 우수한 일치를 보여 골드만 압평안압계로 안압측정이 어려운 경우 리바운드 안압계가 대체 검사법이 될 수 있을 것으로 기대된다.

Abstract

Purpose: To compare the level of accuracy of intraocular pressure (IOP) measurements attained by non-contact tonometer(NCT), rebound tonometer (RT) Icare®, and Tono-Pen (TONO-PEN AVIA®), using Goldmann Applanation tonometer(GAT) as a reference value and to explore their clinical usefulness. Methods: In a prospective study of 71 normal eyes, IOP was measured with NCT, RT, Tono-Pen and GAT. The IOP valuesof were then compared between the eyes. Results: RT showed statistically most significant agreement with the GAT [ICC 0.811, 95%CI 0.712-0.878]. In analysis ofBland-Altman plots, NCT showed the smallest mean bias (+0.2 mm Hg) and widest CI (95%CI; ±5.05 mm Hg), RT showedrelatively small mean bias (-0.7 mm Hg) and narrowest CI (95%CI; ±3.75 mm Hg). Conclusions: There was a significant agreement between the RT and the GAT measurements. We expect RT to be consideredas a reliable alternative when IOP measurement with GAT is not feasible.
