노안 전후 동공크기 변화에 따른 굴절이상과 고위수차 비교 분석
송윤영,위대광,정미아 대한시과학회 2020 대한시과학회지 Vol.22 No.2
Purpose : The purpose of this study was provide information that could be helpful in clinical practice for, presbyopia prescription as, classifying and analyzing refractive errors and highorder aberrations according to changes in pupil size into age groups before and after presbyopia. Methods : Refractive errors and high-order aberrations were measured between 20~80 years of age adults males and females who had no eyes disease and refractive surgery, and they were divided into two groups such as, 20~40 years and 45~80 years. A paired-T test was used to compare refractive errors and high-order aberrations according to the changes in pupil size, and correlation analysis according to age was conducted by Pearson correlation. Results : The spherical equivalent power of 20~40 years was –3.193±2.494 D at 3 mm of pupil size, and the spherical equivalent power at 5 mm was –3.386±2.451 D, showing that myopia of 0.193 D increased. The spherical equivalent power of 45~80 years was 0.015±1.340 D at 3 mm of pupil size, and the spherical equivalent power at 5 mm was –0.054±1.566 D, showing that myopia of 0.069 D increased. In addition, at a pupil size of 3 mm, coma aberration of 0.026 μm, spherical aberration of 0.016 μm, trefoil aberration of 0.037 μm, astigmatism of 0.012 μm, and quatrefoil aberration of 0.022 μm was increased in 45~80 years more than those 20~40 years. Conclusion : When prescribing progressive lenses for presbyopia correction, it is considered to be prescribed with reference to pupil size or high-order aberrations that can degrade vision. 목적 : 본 연구는 동공크기 변화에 따른 굴절이상과 고위수차를 노안 전후의 연령군으로 분류하고 비교 분석하여 노안 처방 등의 임상에 도움이 될 수 있는 정보를 제공하고자 한다. 방법 : 안질환 및 굴절교정 수술을 받은 경험이 없는 20세~80세의 성인 남녀를 20~40세 그룹과 45~80세 두 그룹으로 나누어 굴절이상과 고위수차를 측정하였다. 동공크기 변화에 따른 굴절이상과 고위수차의 비교는 Paired-T test를 이용하였고, 연령에 따른 상관분석은 Pearson correlation으로 실시하였다. 결과 : 20~40세 대상자의 등가구면 굴절력은 동공크기 3 mm에서 –3.193±2.494 D, 5 mm에서 –3.386±2.451D로 0.193 D 근시도가 증가하였으며, 45~80세 대상자의 등가구면 굴절력은 동공크기 3 mm에서 0.015±1.340D, 5 mm에서 –0.054±1.566 D로 0.069 D 근시도가 증가하였다. 또한 동공크기 3 mm에서 20~40세 대상자보다 45~80세 대상자의 코마수차는 0.026 μm, 구면수차는 0.016 μm, 트레포일수차는 0.037 μm, 비점수차는 0.012 μm, 콰트레포일수차는 0.022 μm 증가하였다. 결론 : 노안교정을 위한 누진굴절력렌즈 처방 시 시력을 저하시킬 수 있는 동공크기나 고위수차를 참고하여 처방해야 할 것으로 생각된다.

Purpose : The purpose of this study is to provide basic data to help research to improve the quality of vision by comparing the correlation with high order aberrations according to refractive errors and high order aberrations between myopia, emmetropia and hyperopia groups. Methods : Refractive and high-order aberrations test were measured using i-Profilerplus. High-order aberrations were compared with the Zernike coefficients up to the 4th order of coma, trefoil, spherical, astigmatism, and quadrafoil aberrations in the Zernike polynomial. Results : The coma, spherical, quatrefoil, and the astigmatism aberrations were higher aberrations in women than men. The trefoil aberration was higher aberrations in men than women. Among the high order aberrations of the myopia, emmetropia and hyperopia groups, the coma aberration was the highest at hyperopia with 0.069±0.049 μm. The trefoil aberration was the highest in hyperopia with 0.084±0.072 μm. The spherical aberration was the highest in emmetropia with 0.025±0.043 μm, astigmatism aberration was the highest in emmetropia with 0.028±0.024 μm, and the quatrefoil aberration was the highest in hyperopia with 0.031±0.031 μm. The correlation between the refractive errors and the high order aberrations showed the lower the myopia and the higher hyperopia the more correlated in the positive direction. Conclusion : High-order aberrations showed that trefoil aberration was the highest in the emmetropia and hyperopia groups, while coma aberration was the highest in the myopic group. 목적 : 본 연구는 굴절이상도에 따른 고위수차와의 상관관계, 근시, 정시, 원시 그룹 간의 고위수차를 비교 분석하여 시력의 질을 높이기 위한 연구에 도움이 될 수 있는 기초자료를 제공하고자 한다. 방법 : 굴절검사와 고위수차 검사는 i-Profilerplus 를 사용하였으며, 고위수차는 제르니케 다항식에서 코마, 트레포일, 구면, 비점, 콰트레포일수차의 4차 항까지의 제르니케 계수를 비교 분석하였다. 결과 : 코마수차, 구면수차, 콰트레포일수차, 비점수차는 남자보다 여자가 높게 나타났고, 트레포일수차는 여자보다 남자가 높게 나타났다. 근시, 정시 원시 그룹의 고위수차 중 코마수차는 원시안이 0.069±0.049 μm로 가장 높게 나타났으며 트레포일수차는 원시안이 0.084±0.072 μm로 가장 높게 나타났다. 구면수차는 정시안이0.025±0.043 μm로 가장 높게 나타났고 비점수차는 정시안이 0.028±0.024 μm로 가장 높게 나타났으며, 콰트레포일수차는 원시안이 0.031±0.031 μm로 가장 높게 나타났다. 등가구면굴절력과 고위수차와의 상관성은 근시도가 낮고 원시도가 높을수록 양의 상관성을 나타냈다. 결론 : 고위 수차는 근시 그룹에서는 코마수차, 정시와 원시 그룹에서는 트레포일수차가 가장 높게 나타났다.

송윤영,김경란,박진영,이수영,강지인,이은,안석균,권준수 대한신경정신의학회 2011 PSYCHIATRY INVESTIGATION Vol.8 No.3
Objective Improving quality of life is an important goal in the treatment of schizophrenia. In previous research, quality of life has been reported to be compromised in patients with schizophrenia. The aim of this study was to investigate whether quality of life may be impaired in first-episode schizophrenia patients and to identify the associated factors of quality of life in first-episode schizophrenia. Methods Forty-eight patients with first-episode schizophrenia and 20 normal controls were recruited. Quality of life was measured by using the Quality of Life scale (QLS). General and social self-efficacy, perceived social support were measured by using the self-report scales. The clinical assessments and comprehensive neurocognitive battery were also administered. Results First-episode group showed significantly decreased QLS total and QLS subscale scores compared to normal controls group. The key associated factors of quality of life in patients with first-episode schizophrenia were the negative symptoms and social self-efficacy. Conclusion This finding implies that compromised quality of life may be already emerged in schizophrenia in their first-episode and the psychosocial interventions should be targeting the negative symptoms and the psychosocial protective factors including self-efficacy in addition to simply ameliorating the positive symptoms to foster social reintegration and recovery of first-episode patients.
