목적: 정상안에서 GalileiTM G4 (Zeimer, Port, Switzerland) 와 Pentacam?? (Oculus Inc., Wetzlar, Germany)으로 측정한 각막 고위수차를 비교해 보고자 한다. 대상과 방법: 정상안 41안을 대상으로 한 명의 검사자가 GalileiTM G4와 Pentacam?瑛막? 각각 3회씩 반복하여 각막 고위수차를 측정하였다. 두 수차측정기의 검사자 내 반복성을 급내상관계수(Intraclass correlation coefficient, ICC)로 평가하였으며, 두 기기로 측정된 각막 고위수차 계측치를 비교하고 상관성을 알아보았다. 결과: 정상안에서 GalileiTM G4와 Pentacam?瑛막? 측정한 각막 고위수차의 ICC는 세조각수차, 네조각수차 및 4차, 5차 총 고위수차를 제외한 모든 계측값에서 ICC가 0.81 이상으로 중등도 이상의 반복성을 보였다. 두 기기로 측정한 각막 고위수차의 root mean square (RMS) 값을 비교하였을 때, 총 각막수차(p<0.001), 구면수차(p=0.001) 및 5차 총 고위수차값(p<0.001)에서 두 기기 간에 유의한 차이를 보였다. 또한 기기 간 계측치의 일치도를 평가하였을 때 모든 고위수차 항목에서 두 기기 간에 낮은 일치도를 보였다. 총 각막수차와 구면수차는 두 기기 계측치 간에 통계적으로 유의한 상관관계를 나타내었으나, 그 외의 고위수차 계측값에서는 전반적으로 낮은 상관관계를 나타냈다. 결론: 동일한 원리의 두 기기는 각막 고위수차 측정에서 비교적 높은 재현성을 보이지만, 각막 고위수차 계측치에서 차이를 보이고 두 기기 간 낮은 일치도를 나타내므로 임상에서 상호 호환하여 사용하기에는 제한점이 있을 것으로 사료된다. Purpose: To compare the corneal higher-order aberrations (HOAs) of normal young subjects using GalileiTM G4 (Zeimer, Port, Switzerland) and Pentacam?? (Oculus Inc., Wetzlar, Germany). Methods: Corneal HOAs were measured using GalileiTM G4 and Pentacam?? in 41 healthy individuals (41 eyes). Intraclass correlation coefficients (ICCs) were obtained to evaluate the repeatability of the 2 devices. Differences in HOAs between the 2 instruments were analyzed with a paired t-test and correlations evaluated. Results: All ICCs measured using GalileiTM G4 and Pentacam?? showed more than moderate repeatability (>0.81) except trefoil, tetrafoil, 4th and 5th HOAs. When comparing the measurements obtained with GalileiTM G4 and Pentacam??, total HOAs, spherical aberration (SA), secondary astigmatism and 5th total HOAs were statistically significantly different between the 2 device (all p ≤ 0.001). In addition, GalileiTM G4 and Pentacam?? showed discrepancy among all corneal HOAs items. Although the total corneal HOAs and the SA were significantly correlated, other HOA measurements generally exhibited a low correlation. Conclusions: Corneal HOAs obtained by the 2 instruments cannot be used interchangeably due to their differences and discrepancy although corneal HOAs measured using GalileiTM G4 and Pentacam?? showed relatively high repeatability.

최연정(Yeon Jung Choi),최규룡(Kyu Ryong Choi) 대한안과학회 2015 대한안과학회지 Vol.56 No.12

목적: 한국인 정상안압녹내장 환자에서 Ocular reponse analyzer (ORA; Reichert Inc., Depew, NY, USA)로 측정한 안압 및 각막생체역학 인자의 일중변동에 대해 분석해 보고자 한다. 대상과 방법: 정상안압녹내장 환자 21안을 대상으로 48시간 동안 안압(Goldman’s applanation tonometer [GAT IOP], Goldmanncorrelated IOP [IOPg], corenal-compensated IOP [IOPcc]), 중심각막두께(Central corneal thickness, CCT), corneal hysteresis (CH)및 corneal resistant factor (CRF)를 측정하였다. 측정 1일째와 측정 2일째에 걸쳐 각 인자들이 최고값과 최저값을 보인 시간을 기록하고, 각 인자들의 일중변화를 Repeated measures analysis of variance (Re-ANOVA)를 이용하여 분석하였다. 결과: 측정 1일째(Day 1)와 측정 2일째(Day 2)에 GAT IOP, IOPg 및 IOPcc 모두 6 PM에 최고 안압을 보였으며, 3 PM, 6 PM에도 안압이 높게 측정되었다. 또한 9 PM, 12 AM에는 최저 안압을 보였으며, 유의한 하루 일중 변동을 보였다(Day 1 GAT IOP, IOPg, IOPcc, all p<0.05; Day 2 p=0.052, p=0.056, p=0.001). 반면 CH와 CRF는 뚜렷한 하루 일중변동을 보이지 않았다(p>0.05). 결론: 한국인 정상안압녹내장 환자에서 안압의 일중 변화는 기상 직후와 오후에 높은 안압을, 취침 전에 최저 안압을 보였으며, 의미있는 일중 변동을 나타내었다. 특히 오후 시간에도 상대적으로 높은 안압을 보였기에 실제 임상에서 오후 시간대에 안압을 측정하는것은 높은 안압을 발견하는 데 도움이 될 수 있을 것으로 생각된다. Purpose: To analyze the diurnal change in intraocular pressure (IOP) and corneal biomechanical properties measured using the Ocular Response Analyzer (ORA; Reichert Inc., Depew, NY, USA) in Korean patients with normal tension glaucoma (NTG) patients. Methods: Intraocular pressure (Goldmann applanation tonometer IOP [GAT IOP], Goldmann-correlated IOP [IOPg], corneal-compensated IOP [IOPcc]) and corneal hysteresis (CH), corneal resistance factor (CRF) and central corneal thickness (CCT) were measured in 21 eye of NTG patients (12 males, 9 female) at 3 hour intervals for 48 hours using ORA. We recorded the time of each parameter that showed the lowest and the highest values of during the 48 hour testing period (Day 1 and Day 2) and evaluated the change of diurnal variation using Repeated measures analysis of variance (Re-ANOVA). Results: Peak IOP measured with GAT and ORA occurred at 6 AM-9 AM, 3 PM-6 PM and the trough IOP at 9 PM-12 AM during the 48 hour period. CCT, GAT IOP, IOPcc and IOPg measurements showed statistically significant variations (p<0.05). CH and CRF variations were not statistically significant (p>0.05). Conclusions: In Korean NTG patients, IOP exhibits significant diurnal variation, with higher values during the dawn and afternoon and lower values before retiring. Clinically, measurements of IOP performed in the afternoon could aid in the detection of relatively elevated IOP.

The purpose of study was to examine the physical self-conception and psychological well-being of elderly women participating in senior aerobics. The subjects of this study were 193 people in the elderly welfare center and seniors participating in senior aerobics in the northern part of Gyeongido (Uijeongbu, Yangju, Dongducheon, Pocheon). The survey tool used the physical self-concept scale developed by Kim Byung-Joon(2001) and the psychological well-being scale developed by Hwang Young-Joon(2009) as a questionnaire. The 5-point Likert scale was used. The collected data were analyzed by One-way ANOVA, correlation analysis, and multiple regression analysis. The results of this study were as follows ; First, there was no difference in age, physical self-concept and psychological well-being according to general characteristics(age, exercise duration, frequency, intensity). Second, the correlation between physical self-concept and psychological well-being was positively correlated. Third, physical self-concept is related to psychological well-being. Among the sub-factors of physical self-concept, appearance and overall physical factors influenced sub-factors of psychological well-being. The physical self-concept of elderly women who participated in senior aerobics partially affected psychological well-being.

최연정(Yeon Jung Choi),김윤택(Yun Taek Kim) 대한안과학회 2015 대한안과학회지 Vol.56 No.11

목적: 내경정맥 혈전증(Internal juglar vein thrombosis) 환자에서 나타난 안압 상승에 대하여 피부 경유혈관성형술 후 안압이 정상화 된 1예를 경험하였기에 이를 보고하고자 한다. 증례요약: 58세 남자 환자가 당뇨 망막병증으로 정기 검진을 위해 본원 안과에 내원하였다. 내원 당일 측정된 안압은 우안 30 mmHg, 좌안 28 mmHg였으며, 세극등 현미경으로 시행한 전안부 검사상 결막 부종, 충혈 및 경도의 각막 부종이 관찰되었고 전방각경 검사상 개방각 소견을 보였다. 1달 전부터 시작된 안면 부종을 관찰할 수 있었고, 환자는 2달 전 시행한 경부 전산화단층촬영에서 우측 내경 정맥 혈전증과 좌측 내경정맥 및 완두정맥 폐쇄를 진단 받았다. 이에 대해 피부경유혈관성형술(percutanoeus transluminal angioplasty)을 시행 받았으며, 시술 후 4일째 골드만압평안압으로 우안 15 mmHg, 좌안 12 mmHg로 안압은 정상화되었고 이후 안압 하강제 없이도 정상 안압이 유지되었다. 결론: 내경정맥 혈전증(Internal jugular vein thrombosis) 환자에서 안압 상승 가능성에 대해 염두에 두어야 할 것이다. Purpose: To report a case of elevated intraocular pressure (IOP) caused by internal jugular vein thrombosis. Case summary: A 58-year-old male diagnosed with diabetic retinopathy visited our clinic for a regular checkup. On ophthalmic examination, IOP was 30 mm Hg in the right eye and 28 mm Hg in the left eye. Slit lamp examination showed chemosis, con-junctival injection and slight corneal edema in both eyes. Additionally, gonioscopic examination showed open angle. We ob-served face edema that started 1 month prior and he was diagnosed with internal jugular vein thrombosis on the right side, in-ternal jugular vein and innominate vein stenosis on the left side approximately 2 months ago. The patient underwent percuta-noeus transluminal angioplasty for dilating stenosed vessel. Four days after the procedure, his IOP was 15 mm Hg in the right eye and 12 mm Hg in the left eye based on Goldman applanation tonometer and was well maintained. Conclusions: Internal jugular vein thrombosis on both sides can cause an increase in IOP.

The purpose of this study was to assess the physical activity of preschool children using an accelerometer and investigate differences related to epoch length setting during use of the accelerometer. Subjects of the study were 26 children (12 boys and 14 girls) at the age of 5, enrolled in one preschool located in Gangneung. From 9:00 a.m. to 4:00 p.m. (7 hours period), every child wore a total of four accelerometers (ActiGraph GT3X + , USA), including three attached to the left hip (with epoch length set at 5 seconds, 15 seconds, and 30 seconds). For comparison purposes, a forth was attached to the opposite position, with epoch length set at 5 seconds. Data collected using 15s epoch and 30s epoch (single larger epoch) were compared with those obtained after reintegration of 5s to 15s epoch, 5s to 30s epoch, and 15s to 30s epoch, respectively (smaller epochs reintegrated). According to the results of this study, there were no significant differences in VM between 30s epoch and 5s to 30s epoch reintegrated and in MVPA (moderate-to-vigorous physical activity), between 15s epoch and 5s to 15s epoch reintegrated. From the Bland-Altman plot, reintegration of 15s to 30s epoch in VM and reintegrations of 15s to 30s epoch and 5s to 15s epoch in MVPA can be recommended for assessing physical activity in preschool children. Further research is needed into the reintegration method while using an accelerometer for assessment of energy expenditure in children.

Purpose: We analyzed the pulmonary function and risk factors of allergic rhinitis (AR) in dust mite-sensitized children with current AR and no history of asthma. Methods: In this cross-sectional study, demographic and disease-related information was obtained from 1,792 Korean children aged 9?12 years using a questionnaire, skin-prick testing, spirometric analysis, and methacholine challenge testing. Results: A total of 672 children were analyzed. The control group consisted of 583 children without any allergic diseases who were not sensitized to 16 common allergens. The group with current AR and dust mite sensitization consisted of 89 children. Binary logistic regression analysis showed that helminth infection (adjusted odds ratio [aOR], 2.88; 95% confidence interval [CI], 1.23?6.77) and antibiotic use during infancy (aOR, 1.89; 95% CI, 1.10?3.25) were the risk factors. Pet ownership (aOR, 0.32; 95% CI, 0.15?0.69) and older siblings (aOR, 0.58; 95% CI, 0.35?0.96) were protective factors. Spirometry results did not differ between the control and dust mite-induced AR groups. None of the children showed a bronchodilator response. However, 8.5%, 7.1%, and 2.1% of the control-group children and 28.7%, 23.0%, and 8.0% of the dust mite-induced AR-group children showed methacholine PC20 (provocative concentration of methacholine causing a 20% fall in forced expiratory volume in 1 second) values of ≤25 mg/mL, ≤16 mg/mL, and ≤8 mg/mL, respectively (P<0.01). Conclusion: The prevalence of current dust mite-induced AR may be reduced by controlling environmental factors. Even though the spirometry results seemed to be normal, bronchial hyperresponsiveness occurred more frequently in children with dust mite-induced AR than in normal children.
