Purpose: To evaluate the factors affecting the visual acuity and stereoacuity of patients with refractive accommodative esotropia who have successful optical alignment obtained by refractive error management. Methods: The charts of 60 patients, including medical history, age of onset, chief complaint at first visit, age at which glasses were first worn, refractive error, visual acuities with and without glasses, angle of deviation, and stereoacuity were retrospectively reviewed. Results: The mean follow-up period was 59.20 ± 40.26 months, and the mean hypermetropia at the initial visit was 4.90 ± 1.75 diopters (D). Fifty-three patients had decreased hypermetropia, with a mean of 0.94 ± 0.91 D, while seven patients had increased hypermetropia, with a mean of 0.38 ± 0.17 D. The mean deviation at the initial visit was 28.40 ± 9.05 prism diopters (PD) at near without glasses and decreased to 3.20 ± 3.50 PD with glasses at the final visit. Children who had anisometropia at the initial visit had a higher prevalence for amblyopia at the final visit (p = 0.000). However, the degree of hypermetropia, age at onset, deviation before glasses correction, interval from onset to glasses correction, and amblyopia at diagnosis were not significant risk factors for amblyopia or anomalous streoacuity at the final visit. Conclusions: The degree of hypermetropia, age at onset, deviation before glasses correction, interval from onset to glasses correction, and amblyopia at diagnosis were not significant risk factors for amblyopia. However, anisometropia was a significant risk factor for the development of amblyopia in patients with refractive accommodative esotropia, and these children should receive careful and long-term follow-up management.

배경: 판막대치술에 냉동보존판막의 이용은 감염에 대한 저항성과 탁월한 혈류역학으로 증가하고 있다. 판막육아세포의 생존율은 이식된 냉동보존 판막의 내구성에 영향을 미친다고 알려져 있고, 세포의 생존율은 warm ischemic time에 영향을 받는 것으로 알려져 있다. 냉동 보존하여 이식할수 있는 공여 판막의 warm ischemic time 의 적정치를 구하기 위하여, warm ischemic time에 다른 세포의 생존율을 관찰하였다. 대상 및 방법: 1.조직의 획득: 실제 판막을 냉동 보존하는 상황과 유사하게 하기 위하여 도살된 돼지의 심장과 폐를 밀봉한 상태로 4~8$^{\circ}C$로 냉장 보관하여 (warm ischemic time) 일정시간이 경과한 후, 심장과 폐에서 심장을 적출하여 4$^{\circ}C$하트만 용액에 24시간 보관하였다.(cold ischemic time). Warm ischemic time에 따라 2시간, 12시간, 24시간 36시간으로 4군으로 나누었으며, 각 군마다8개의 돼지 심자을 이용하였다. 2. 조직의 멸균: RRMI 1640에 항생제를 섞은 용액에 멸균하고, 3 냉동과 냉동보존; American tissue bank에서 제시한 냉동곡선에 따라 냉동하여, 액체질소 탱그에서 7일간 보존 후 해동하였다. 4. 생존율의 측정; 판막의 생존율 검사는 Triphan blue test로 하였고, 각각 warm ischemic period후 , cold ischemic period 후, 해동 후에 시행하였다. 5. 분석방법; 분석은 SAS program의 pearson correlation으로 하였다. 결과: 1. 멸균, 냉동과 냉동 보존하는 과정의 적합성을 규명하기 위하여 이 과정의 전과 후인 Cold ischemic period 후와 해동 후의 대동맥판막의 생존율의 차이를 비교한 결과, 차이가 없었다.(p =0.619). 2, warm ischemic time 과 warm ischemic period 후 , Cole ischemic period 후와 해동후의 대동맥판막의 생존율과의 correlation 은 각각 R= -0.857, -.0.673과 -0.549로 강하거나 , 혹은 뚜렷한 음성적 관계가 있었다. 삼천판막의 생존율과 대동맥판막의 생존율과 뚜렷한 상관관계가 있었다. 결론; 1. Warm ischemic time 이 길어지면 판막유아세포의 생존율이 감소하고, 12시간 이상되면 해동후의 판막육 아페포의 생존율이 50% 이하로 떨어졌다. 2. 본 연구에서 시행한 판막의 냉동보존방법은 세포의 생존율을 유지하는데 양호한 것으로 나타났으며 삼천판막으로 대동맥판막의 생존율을 예측해 볼 수 있다. 3. 그러나, 이식후 장기간 적절한 내구성을 갖기 위한 이식될 판막의 생존율은, 육아세포에 관한 여구가 좀 더 되어야 규명될 것이다.

김임규(Im Gyu Kim),이종은(Chong Eun Lee),이준석(Jun Seok Lee),서 샘(Sam Seo),이규원(Kyoo Won Lee) 대한안과학회 2016 대한안과학회지 Vol.57 No.10

목적: 파장가변 빛간섭단층촬영계(swept source optical coherence tomography, SS-OCT)로 측정한 중심각막두께를 초음파 각막두께측정계(ultrasound pachymetry), Orbscan II, 전안부 빛간섭단층촬영계(anterior segment optical coherence tomography, AS-OCT)로 측정한 중심각막두께와 비교하여 SS-OCT의 임상적 일치율의 유용성을 알아보고자 하였다. 대상과 방법: 한 명의 검사자가 65명 65안의 정상안을 대상으로 Orbscan II, AS-OCT, SS-OCT, 초음파 각막두께측정계의 순서로 중심각막두께를 측정하여 상관관계를 비교, 분석하였다. 결과: Orbscan II, AS-OCT, SS-OCT와 초음파 각막두께측정계를 이용하여 측정한 각각의 평균 중심각막두께는 각각 534.83 ±38.46, 517.80 ± 32.48, 528.22 ± 33.71, 528.02 ± 34.90 μm였다. 4가지 검사기기에서 높은 상관관계를 보였으며(r>0.894, p<0.001 in all groups), SS-OCT와 초음파 각막두께측정계를 이용한 측정치에서 통계적으로 유의한 일치율을 보였다(p=0.782). 결론: 정상인에서 SS-OCT로 측정한 중심각막두께가 초음파 각막두께측정계로 측정한 값에 높은 일치율을 보여, 정상인의 중심각막두께 측정에 SS-OCT가 초음파 각막두께측정계를 대체할 수 있는 유용한 방법이라 생각된다. <대한안과학회지 2016;57(10):1542-1548> Purpose: To evaluate the efficacy of swept source optical coherence tomography (SS-OCT) by comparing the measurement of central corneal thickness (CCT) to the measurement obtained using Orbscan II, anterior segment optical coherence tomography (AS-OCT) and ultrasound pachymetry. Methods: One examiner measured the CCT in 65 eyes of 65 healthy subjects using Orbscan II, AS-OCT, SS-OCT and ultrasound pachymetry. The mean values and correlations were analyzed. Results: The average CCT measurements obtained using Orbscan II, AS-OCT, SS-OCT and ultrasound pachymetry were 534.83 ± 38.46, 517.80 ± 32.48, 528.22 ± 33.71 and 528.02 ± 34.90 μm, respectively. A significant linear correlation was observed among Orbscan II, AS-OCT, SS-OCT and ultrasound pachymetry (r > 0.894, p < 0.001). There was no significant difference between the SS-OCT and ultrasound pachymetry (p = 0.782). Conclusions: The results of the 4 methods were significantly correlated and the SS-OCT reached a high level of agreement when CCT was determined using ultrasound pachymetry. The CCT measurements using SS-OCT is a better alternative for ultrasound pachymetry than Orbscan II and AS-OCT. J Korean Ophthalmol Soc 2016;57(10):1542-1548

This study was conducted during the time period of September 1997 to February 1999. in order to provide data concerning important facets of horne care nursing and the degree to which practicing hospital and public health nurses believe themselves to be competent in each area. The study subjects consisted of 610 hospital nurses, 158 public health nurses and 21 other nurses from Seoul and the province of Kyunggi. Korea. Data was collected through self-reporting questionnaires which was used by Kim et al.(1999) to evaluate the status of home health nursing and the varying ideas of self-competence that practicing nurses have. The results of the study were as follows: 1) The mean scores of perceived important components and competencies on home health nursing measured on the Likert 4 point scale were $3.15{\pm}0.36$ for importance. and $2.56{\pm}0.36$ for competency. Of the four categories regarding nursing services, the 'Nursing skill' factor had the highest importance and competency. 2) There were significantly higher scores for hospital nurses' importance components and competencies of home care nursing as compared to those scores for public health nurses. 3) The significant factors of the importance component of home care nursing listed in order of priority were 'general infection control', 'bed sore care skill', 'rehabilitation care', 'keeping maintenance of the client's confidentiality', 'malpractice', 'diabetes patient care', 'ability for problem solving' respectively. In contrast, of low priority in the importance components of home care nursing were 'referring nursing as a job to others'. 'record keeping', 'family dynamics', 'medical equipment', 'economic problems', 'environmental assessment', 'suture removal', 'multidisciplinary coordination' respectively. 4) The high priority of the degree to which practicing nurses believe themselves to be competent in home health nursing were the 'blood sugar test', 'enema skill', 'injection skill', 'skin care', 'bed sore care skill', etc. In contrast, lower competence for home care nursing as perceived by nurses were 'AIDS care', 'family violence care', 'substance abuse care', 'mental health care' respectively.
