Abstract

Purpose : The purpose of this study was to investigate the temperature changes of the ocular surface before and after cataract surgery using thermography of a thermal imaging camera. Methods : The study included 75 patients (75 eyes) aged from 50 to 79 years who underwent cataract surgery. In the past, those who underwent corneal-related surgery, wearing contact lens, disorder of tear secretion and taking medication for systemic disease were excluded from this study. The temperature changes of the eyeball surface were measured using a thermal imager (Cox CX series, Answer, Korea) following Tear Break Up Time (TBUT) test, Mcmonnies questionnaire and Schirmer's Test in real time, Results : While the temperature of preoperative ocular surface was $35.20{\pm}0.54^{\circ}C$ and that of postoperative temperature was $35.30{\pm}0.53^{\circ}C$, the difference was not significant. The temperature changes in the ocular surface were statistically significant at $-0.12{\pm}0.08{\Delta}$ ($^{\circ}C/sec$) before the surgery and $-0.18{\pm}0.07{\Delta}$ ($^{\circ}C/sec$) after the surgery. In comparison of the age groups, it was shown that the changes in the surface temperature before the surgery were from $-0.19{\pm}0.05{\Delta}$ ($^{\circ}C/sec$) to $-0.14{\pm}0.09{\Delta}$ ($^{\circ}C/sec$) in the 50s group, and from $-0.12{\pm}0.08{\Delta}$ ($^{\circ}C/sec$) to $-0.15{\pm}0.07{\Delta}$ ($^{\circ}C/sec$) in 60s group, and $-0.18{\pm}0.07{\Delta}$ ($^{\circ}C$) to $-0.12{\pm}0.08{\Delta}/sec$) in the 70s group, showing significant changes in the ocular surface temperature at all ages. Conclusion : Following the cataract surgery, all the indicators of dry eye syndrome were decreased, and eye surface temperature changes were significant. The thermography technique of the ocular surface would be expected to be useful for the evaluation of various dry eye syndromes because it is easy to evaluate dry eye syndrome noninvasively and can be quantified.

목적 : 백내장 환자를 대상으로 수술 전과 후의 안구표면의 온도변화 양상을 열화상카메라의 서모그래피를 이용하여 연구 하고자 하였다. 방법 : 본 연구는 백내장 수술을 받은 환자 50-79세까지 75명 75안의 환자 군을 대상으로 하였다. 과거에 굴절교정수술, 각막관련 수술을 받은 자와 콘택트렌즈를 사용하는 자, 눈물관 이상자, 전신질환 치료 약물을 복용하는 자 등 눈물분비와 눈물막에 영향을 줄 수 있는 자는 연구 대상자에서 제외하였고 눈물막파괴시간 검사(Tear Break Up Time, BUT), 쉬르머 검사(Schirmer's Test), 맥모니테스트(Mcmonnies questionnaire)를 시행한 후 열화상카메라(Cox CX series, Answer., Korea)를 이용하여 안구표면의 온도변화를 실시간으로 측정하였다. 결과 : 전체 대상자의 술 전 안구표면 온도는 $35.20{\pm}0.54^{\circ}C$이었고 술 후에는 $35.30{\pm}0.53^{\circ}C$로 표면온도가 상승하였으나 유의한 차이를 보이지 않았다. 안구표면 온도변화는 술전에서 $-0.12{\pm}0.08{\Delta}$ ($^{\circ}C/sec$)에서 술 후 $-0.18{\pm}0.07{\Delta}$ ($^{\circ}C/sec$)로 통계학적으로 유의한 결과를 나타냈다. 연령 별 비교에서는, 50 대군은 백내장 술 전 대상자의 안구표면 온도변화가 $-0.14{\pm}0.09{\Delta}$ ($^{\circ}C/sec$)에서 $-0.19{\pm}0.05{\Delta}$ ($^{\circ}C/sec$)으로 나타났고 60 대군에서는 $-0.12{\pm}0.08{\Delta}$ ($^{\circ}C/sec$)에서 $-0.15{\pm}0.07{\Delta}$ ($^{\circ}C/sec$)으로 나타났으며 70 대군에서는 술 전 대상자의 안구표면 온도변화는 $-0.12{\pm}0.08{\Delta}$($^{\circ}C/sec$)에서 $-0.18{\pm}0.07{\Delta}$($^{\circ}C/sec$)으로 전 연령에서 모두 유의한 안구표면 온도변화를 보였다. 결론 : 백내장 술 후에는 안구건조증 평가지표가 모두 감소하였고 안구표면 온도변화가 유의함을 보였다. 안구표면의 서모그래피 기술은 비침습적으로 안구건조증을 평가하는데 용이하였고 객관적으로 수치화할 수 있는 장점이 있어 다양한 안구건조증 연구에 활용 될 것으로 기대된다.
