목적 : 청년층 건성안의 원인을 평가하고자, 정상안과 건성안의 눈물막을 비교분석하였다.
방법 : 청년 24명(48안, 남 11명, 여 13명, 평균연령 22.04±2.01세)을 대상으로 SPEED 건성안 설문지를 이 용하여 건성안을 판별하고, 눈물검사값을 정상안의 검사값과 비교하였다. 눈물의 양은 OCCUTUBE로, 눈물막 안 정성은 눈물막파괴시간검사(TBUT)로 평가하였다. 눈물지방층두께(LLT)와 눈깜박임 양상 및 마이봄샘 이상은 LIPIVIEW IIⓇ로 측정하고 Image JⓇ 프로그램을 이용하여 분석하였다.
결과: 건성안의 SPEED 설문값은 10.63±3.78점으로 높게 측정되었고, TBUT는 3.39±0.89초, OCCUTUBE 측정값은 2.67±0.92 mm로 정상안 (4.04±0.83초, 3.44±1.42 mm)보다 유의하게 짧았다(p=0.019, p=0.039). 불완전한 눈깜빡임 비율은 건성안의 경우 66.88±33.43%로 정상안의 23.63±25.66%보다 높았으나 LLT와 마이 봄샘 손상은 유의한 차이가 없었다.
결론 : SPEED 설문지로 건성안을 판별한 결과 청년층에서 건성안의 비율은 매우 높았으며, 건성안 증상은 눈 물의 양, TBUT 및 불완전한 눈깜빡임과 연관이 있었다.

Purpose : To evaluate the cause of dry eye in youth, comparison between the tear film of
normal eye and dry eye was performed.
Methods : For 24 young adults (48 eyes, 11 males, 13 females, average age 22.04±2.01 years
old), dry eyes were screened using the SPEED dry eye questionnaire, and compared tear test
results of dry eyes with those of normal eyes. The amount of tear was evaluated by OCCUTUBE,
and the stability of the tear film was evaluated by the tear film break-up time test (TBUT).
Tear lipid layer thickness (LLT), blinking pattern, and meibomian gland damage were measured
with LIPIVIEW II® and analyzed using Image J® program.
Results : In the dry eyes, the SPEED questionnaire score was measured as high as
10.63±3.78 points, the TBUT was 3.39±0.89 s, and OCCUTUBE measurement was 2.67±0.92
mm, which was significantly shorter than those of the normal eye (4.04±0.83 s, 3.44±1.42
mm) (p=0.019, p=0.039, respectively). The rate of incomplete blinking in the dry eyes was
66.88±33.43%, which was higher than 23.63±25.66% in normal eyes, however, there was no
significant difference between LLT and meibomian gland damage.
Conclusion : As a result of screening dry eyes with the SPEED questionnaire, the percentage
of dry eyes was very high in young people, and dry eye symptoms were associated with tear
volume, TBUT, and incomplete blinking.
