목적 : 본 연구는 정확한 처방에 의한 근용 안경 사용의 필요성을 알아보기 위하여 기성돋보기를 사용하고 있는 사람들을 대상으로 기성돋보기 사용자들의 변수를 측정하여 비교 분석하였다. 방법 : 연구대상자는 45세 이상 기성돋보기를 사용 중인 총 50명을 선정하여, 굴절검사와 최대조절력, 근용가입도, 근용 PD를 측정하였다. 또한, 사용 중인 기성돋보기 안경테 기준점간 거리와 안경렌즈 광학중심점간 거리를 측정하였다. 결과 : 기성돋보기의 구입 시기에 따른 가장 선명한 거리를 확인한 결과 구입 시기가 오래될수록 선명한 거리가 길어졌다. 기성돋보기의 안경테 기준점간 거리와 광학중심점간 거리를 비교한 결과 안경테의 기준점간 거리가 클수록 광학중심점간 거리도 커졌고, 광학중심점간 거리와 근용 PD가 2 mm 이상 차이가 나는 경우가 71.00% 인 것으로 나타났다. 또한, 양안시에 영향을 미치는 유발 프리즘을 확인한 결과 80.00%에서 BO △, 16.00%에서 BI △이 유발되는 것으로 나타났다. 결론 : 본 연구로 기성돋보기 안경과 실제 처방 근용 안경의 굴절력과 PD 차이로 양안시에 유발되는 사위로 인한 안정피로를 확인 할 수 있었다. 따라서, 눈 건강에 악영향을 미칠 수 있는 기성돋보기 사용을 예방하기 위하여 온라인을 포함한 기성돋보기 안경의 판매 기준과 안경사의 전문성 강화를 통해 국민 안보건 서비스의 질적 향상이 필요하다. Purpose : In this study, in order to find out the necessity of using reading glasses according to the correct prescription, the variables of the users of the ready-made reading glasses were measured and analyzed for those who are using the ready-made reading glasses. Methods : A total of 50 subjects over 45 years of age were selected, and refraction tests, maximal accommodation, near addition, and near PD were measured. In addition, the distance between center points of the ready-made reading glasses frames and the distance between the optical center points of the glasses were measured. Results : As a result of checking the clearest distance according to the purchase period of the ready-made reading glasses, the clearest distance became longer as the period of purchase increased. As a result of comparing the distance between the reference points of the glasses frames and the distance between the optical center points of the ready-made reading glasses, the larger the distance between the reference points of the frames, the larger the distance between the optical center points. It was found that 71.00% had a difference of 2 mm or more. In addition, as a result of confirming the inducing prism affecting binocular vision, BO △ was induced in 80.00%, BI △ was induced in 16.00%. Conclusion : This study was able to confirm the eye strain caused by the different refractive power and PD between the ready-made reading glasses and the actual prescription glasses for near vision use. Therefore, standards for selling ready-made reading glasses, including online and it is necessary to improve the quality of national security services by strengthening the expertise of optometrist to prevent the use of ready-made reading glasses which may adversely affect eye health.

Analysis of Response to Prism Stimulation in Exophoria Patients
Dae-Gwang Wi,Hyun-Sung Leem 대한시과학회 2017 대한시과학회지 Vol.19 No.1
목적: 안위이상을 갖는 환자들을 대상으로 프리즘 자극에 대한 실제 반응의 차이를 확인해 보고자 하 였다. 방법: 안질환이 없고 교정시력이 20/20 이상인 외사위를 갖는 25명을 대상으로 대약시경을 이용하여 자 각적 사시각과 타각적 사시각, 이상각을 측정하였다. 또한 대약시경의 잔상전이검사를 이용하여 프리즘 자 극에 대한 반응을 확인하였다. 결과: 전체 대상자 25명 중 이상망막대응은 16명(64%)이었고, 그 중 조화이상망막대응과 부조화이상망막 대응은 각각 5명(20%), 11명(44%)이었다. 이상망막대응의 유병률은 안위이상 정도에 따라 나눈 두 그룹 모 두에서 정상망막대응 보다 많았지만, 정상망막대응과 이상망막대응 모두 안위이상 정도와 낮은 상관관계로 확인 되었다(p=0.25, p=0.53, p=0.38). 잔상전이검사에서 초기 잔상 위치는 이상각과 통계적인 유의한 상 관관계가 있었다(p<0.05). 프리즘 자극에 대하여 나타난 실제융합성움직임을 이상망막대응에서 확인할 수 있었으며(p<0.05), 실제융합성움직임이 멈추는 지점과 이상각에서 통계적으로 유의한 결과를 나타내었다 (p<0.05). 결론: 이상각을 포함한 대응 상태의 확인이 수술 또는 비수술적 처치하는데 필요한 자료로 도움이 될 것 으로 사료된다. Purpose: The objective of the present study was to identify the differences in real responses to prism stimulation in patients with exophoria. Methods: The present study involved 25 participants with exophoria who did not have any eye disease and had best correct visual acuity of 20/20 or better. A synoptophore was used to measure the subjective and objective deviation angles, as well as the angle of anomaly. Moreover, responses to prism stimulation were identified using afterimage transfer test with the synoptophore. Results: Among the total of 25 participants, 16(64%) showed anormalous retinal correspondence (ARC), with 5(20%) and 11(44%) having harmonious and unharmonious ARC, respectively. Prevalence of ARC was higher than normal retinal correspondence(NRC) in both groups divided according to amount of deviation angle. However, both NRC and ARC were found to have low correlations with amount of deviation angle(p=0.25, p=0.53, p=0.38). In the afterimage transfer test, position of the initial afterimage had a statistically significant correlation with angle of anomaly(p<0.05). Real fusional movement(RFM) in response to prim stimulation was identified in ARC(p<0.05), and the point at which RFM stopped and angle of anomaly showed statistically significant results(p<0.05). Conclusions: It is concluded that identification of responsive state, including the angle of anomaly, may be helpful as data needed during surgical and/or non-surgical treatment.

Case report of a pancreatic squamoid cyst
Dae-Gwang Yoo,Shin Hwang,Dae-Wook Hwang,Ki-Hun Kim,Chul-Soo Ahn,Tae-Yong Ha,Gi-Won Song,Dong-Hwan Jung,Gil-Chun Park,Sung-Gyu Lee 한국간담췌외과학회 2013 한국간담췌외과학회지 Vol.17 No.4
Squamoid cyst of the pancreas is a very rare disease and it has been proposed only recently as a distinct pathologic lesion. We herein present a case of pancreatic squamoid cyst in a patient who underwent laparoscopic resection. A 60-year-old woman had an abdominal computed tomography (CT) scan for a routine check-up, and a multi-cystic lesion of 1.8-cm in size was incidentally found in the tail of the pancreas. Biochemical laboratory tests were within normal limits. At first, we presumed that the most likely diagnosis of the cystic lesion was an intraductal papillary mucinous neoplasm. To treat this lesion, we performed laparoscopic spleen-saving distal pancreatectomy. The patient showed the usual routine postoperative course and she was discharged 10 days after surgery. On examination of the resected specimen, a well-defined, oligolocular cystic mass was found in the pancreatic tail, without a solid portion. Histologic examination revealed that the cysts had linings ranging from flat squamoid cells to transitional cells with non-keratinization. After immunohistochemical staining, the final diagnosis was confirmed to be squamoid cyst of the pancreas. This lesion appears to be regarded as a benign entity, thus an extended operation should be avoided and resection of the lesion can be performed minimally.

A Case of Normal Retinal Blood Vessel Pattern Using Fundus Camera
Dae-Gwang Wi,Mi-A Jung,Hyun-Sung Leem 대한시과학회 2021 대한시과학회지 Vol.23 No.2
정상 망막을 가진 대상자에서 나타난 망막혈관 형태의 특이 양상을 보고하고자 한다. 안과적 병력이 없고 정상 시력인 22세 여성 대상자의 안저 검사를 실시하였다. 빛간섭 단층촬영 측정결과 망막신경섬유층 두께와 시신경유 두 함몰/시신경유두 직경은 정상이었다. 안저카메라를 이용한 망막혈관 분포의 양상을 확인한 결과 망막중심동맥이 기시하는 시신경유두 부위는 특이 양상은 없었으나 우안의 망막중심동맥이 귀쪽 방향으로 주행 후 상하분지로 나누어지는 현상이 관찰 되었다. 안과적 질환이 없는 정상안에서도 망막중심동맥의 형태를 분류하는 10개의 양상에 포함되지 않는 혈관의 주행이 있을 수 있어 추가적인 확인이 필요할 것으로 사료된다. The purpose of this study is to report the specific pattern of retinal blood vessel morphology in subjects with normal retina. The fundus of a 22-year-old female subject with normal ophthalmic history and visual acuity was tested. In optical coherence tomography, retinal nerve fiver layer thickness and C/D ratio were normal. As a result of confirming the distribution of retinal blood vessels using a fundus camera, there were no specific findings in the optic nerve papilla originating from the central retinal artery. But it was observed that the central retinal artery in the right eye divided into upper and lower branches after toward the ear. There may be retinal blood vessels travel that is not included in the 10 modalities that classify the morphology of the central retinal artery. Therefore, it is considered that additional confirmation is necessary.

( Min Dae Kim ),( Dae Hwan Kang ),( Jong Hwan Park ),( Jin Ho Lee ),( Cheol Woong Choi ),( Do Hoon Kim ),( Hyung Wook Kim ),( Gwang Ha Kim ) The Editorial Office of Gut and Liver 2010 Gut and Liver Vol.4 No.2
Surgical resection is the mainstay treatment for gastrointestinal stromal tumors (GISTs). Laparoscopic surgery can be considered for treating these tumors since their biologic behavior lends them to curative resection without requiring large margins or extensive lymphadenectomy. Despite complete resection, GISTs frequently recur specifically in the liver and peritoneum. Although they occur in other upper gastrointestinal malignancies, recurrences of GISTs at the port sites after laparoscopic surgery have rarely been reported. We describe here a patient with abdominal wound metastasis after laparoscopic surgery for GIST. (Gut Liver 2010;4:283-286)
