Purpose: To report clinical and laboratory findings of toxic anterior segment syndrome (TASS) in seven patients following cataract surgery with intraocular lens (IOL) implantation. Methods: The medical records of seven patients who underwent cataract surgery associated with postoperative decreased visual acuity, ocular pain, anterior chamber inflammation and corneal edema between Feb 2007 and Nov 2009 were retrospectively reviewed. Results: All patients were over 60 years of age, four patients had diabetes and four patients had cardiovascular disease. Five patients had received hydrophilic IOL, and six patients underwent surgery later in order. All seven patients presented with increased anterior segment inflammation, acute decreased visual acuity, and severe corneal edema an average of 10.4 days (range 1 to 15 days) after surgery. Treatment of the seven patients included intensive topical and oral steroids, and improvement was noted in all patients. Conclusions: The incidence of TASS after cataract surgery was 0.8%, and was significantly higher in cases of hydrophilic IOL insertion (5 of 284 cases, 1.76%) compared to cases of hydrophobic IOL insertion (2 of 581 cases, 0.34%) (p = 0.04). Five of the seven cases presented with TASS at postoperative day 14. Inflammation improved in all patients with steroid treatment. J Korean Ophthalmol Soc 2011;52(6):690-695

Purpose: To evaluate the radiographic volume change in extraocular muscles (EOM) following orbital wall decompression for Nunery type 1 and type 2 thyroid-associated orbitopathy (TAO). Methods: Medical records of 31 orbits in 20 patients undergoing postoperative orbital CT after orbital decompression for TAO were retrospectively reviewed. The patients were divided according to Nunery classifications. A type 1 classification was assigned to patients who had no diplopia and essentially normal versions. A type 2 classification was assigned to patients with restrictive motility loss and diplopia within 20 degrees of the primary position. EOM volumes were determined by the summation of each EOM’s cross-sectional areas in the coronal plane of the CT scans and multiplying the sum by the slice thickness. Main outcome measure was a comparison of EOM volume changes between types 1 and 2 TAO and a relationship between EOM volume and change in proptosis. Results: In type 2 TAO, a significant increase in the volume of the medial rectus muscle, lateral rectus, and total EOM was detected postoperatively (p = 0.044, 0.022, 0.049), whereas no significant changes were found in the EOM’s volume changes in type 1 TAO. The reduction of proptosis after orbital decompression in type 1 TAO was significantly greater than in type 2 TAO (p = 0.025). A significant positive association was observed between the preoperative EOM volumes and the reduction of proptosis following orbital wall decompression (r = 0.505). Conclusions: The postoperative EOM volumes following orbital wall decompression was significantly increased in Nunery type 2 patients who had restrictive myopathy.

Purpose: To compare the changes in strabismus angle and deviation between two groups: a bilateral lateral rectus recession (Group 1) and a unilateral lateral rectus recession in exotropia (Group 2). Methods: A retrospective survey was conducted on 198 patients who had received exotropia surgery in our ophthalmology clinic from September 2003 to April 2007. A total of 116 patients were in Group 1, and 82 patients were in Group 2. Unilateral lateral rectus recession was performed on patients under 25 PD, and bilateral lateral rectus recession was performed on patients above 25 PD. A case of less than 4 PD esodeviation and less than 10 PD exodeviaton was defined as a success and any other case as a failure at the 1-year follow-up visit. Results: The average deviations of the first postoperative month and the first postoperative year were -1.96 D ± 4.75, 2.5 D ± 7.82 for Group 1 and 0.77 D ± 2.87, 5.94 D ± 3.38 for Group 2. Revealing statistical significance between the 2 Groups: Group 1 had 30 failure cases (25.9%) and their 1 postoperative year average deviation was 5.42 D ± 13.97, while Group 2 showed 24 failure cases (29.3%) and their 1-postoperative-year average deviation was 13.0-79 ± 3.04. Group 1 had less strabismus angle and a greater standard deviation than Group 2, as Group 1 had more overcorrection. Among the 30 failure cases of Group 1, 9 were overcorrected and 21 were undercorrected, but all 24 failure cases in Group 2 were undercorrected. Conclusions: The strabismus angle after lateral rectus recession showed a wider variation and a larger difference in bilateral lateral rectus recession than in the unilateral lateral rectus recession.

철도역사의 혼잡성이 역사 공공서비스공간에 미치는 영향

황규연 ( Gyuyeon Hwang ),이정교 ( Jyeonggyo Lee ) 한국공간디자인학회 2015 한국공간디자인학회논문집 Vol.10 No.5

(연구배경 및 목적)철도역사는 이용행태 및 수요변화에 따라 복합적인 기능으로 진화되어왔다. 상업 및 문화시설의 도입, 타교통 수단과의 연계를 통한 다중적 기능 및 규모로 확대되고 있다. 하지만 기준 없는 무분별한 개발 및 매장, 광고시설의 난립으로 혼잡한 역사 환경을 형성하고 있는 실정이다. 이러한 문제점들은 공공교통시설에서 이동 동선 흐름방해, 정보과다 및 중복설치로 인한 혼란초래, 공간 이용 혼란 등 역사 내 순기능인 공공성 및 이동편의성에 절대적인 상관관계가 있다. 본 연구는 철도역 사내에서 혼잡성 및 공공서비스에 대한 연구를 통하여 원활하고 편리한 공공교통시설 이용과 종합적 조화를 고려한 환경개선에 기여, 기존철도역사의 인식제고 및 순기능회복에 그 목적을 둔다. (연구방법)본 연구는 철도역사의 혼잡한 환경과 제공되어야 하는 공공서비스와의 상관성에 초점을 두고, 선행연구 조사 및 이론적 고찰을 통해 혼잡성의 개념정립과 공간이용자에게 미치는 특성을 연구한다. 또한 선행연구를 통한 철도역사의 개념정립과 제공되어야 할 공공서비스 특성에 대하여 연구하고 고객동선상의 공간 구성요소를 추출하여, 이들 중 환경혼잡성 유발로 인한 공공시비스에 영향을 미치는 요소 및 원인을 분석한다. 이러한 연구결과를 근거로 도출된 평가지표에 의하여 국내외 대형역사 6곳을 선정, 비교분석하고 문제점 및 개선방향을 도출한다. (결과)연구결과 혼잡은 인적혼잡인 ‘밀도와’물리적·공간적 측면인 ‘혼잡’으로 이원화 시켜 접근할 수 있으며, 특히 후자에 해당하는 환경혼잡성은 공간이용자에게 부정적인 감정을 유발하고 그 부정적 감정은 공간회피 행동으로 나타난다. 또한 시간압박은 혼잡에 대하여 더 강한 부정적 요소로 나타나는데 이동을 목적으로 하는 철도역사공간에서 혼잡의 조절은 공공서비스에 직접적 영향을 미친다. 철도역사에서 제공되어야할 공공서비스 요소는 물리적, 심리적 접근성, 그 공간을 잘 이해하기 위한 일관성, 이용자의 긍정적 감정 유도를 위한 쾌적성, 개방 및 연계를 통한 안전성으로 구분 할 수 있다. 이들은 철도역사 공공공간 구성요소인 교통이용시설, 정보안내시설, 안전·방재시설, 상업시설, 광고시설의 상호관계성에 의하여 영향을 받는다.(결론)그러므로 중요도에 따라 범위 및 범주를 설정, 직각적 인지 및 심리적 혼란을 최소화 하여야 하고, 기능별, 요소별 통합 및 최소설치를 통한 환경과의 조화를 고려하여야하며, 기능별 동선의 효율적 유도를 위한 조닝계획 및 동선계획이 필요하다. 또한 관리·운영단 계에서의 고려가 아닌 설계, 건설, 관리·운영 단계에서 활용할 수 있는 명확한 기준을 통하여 순기능 회복뿐 아니라, 나아가 문화복합공간으로써 고품격화 된 공간으로 탈바꿈 하여야 한다. (Background and Purpose) Railway stations have been developed with complex functions based on changes in use behaviors and demands. Commercial and cultural facilities have been introduced with multiple functions and larger scales in combination with other transportation means. However, thoughtless development and disordered positioning of shops and advertising facilities have resulted in confusion in station environments recently. Such problems cause hindrances to human traffic in public transportation facilities; examples include excessive information and duplicate installations and disorder in space use, which are absolutely correlated with publicity and movement convenience for proper functioning of a station. An aim of this study includes examining crowding and public services in railway stations, with the intent of promoting smooth and convenient use of public transportation facilities. These improvements would contribute to environmental upgrades for comprehensive harmony with the surroundings, greater awareness of existing railway stations, and recovery of proper functions. (Method) The focus of this study is the correlation between crowding and public services in railway stations. The concept of crowding is established, and its effect on space users is examined based on the documentary investigation of existing researches. In addition, space components related to user traffic have been extracted to analyze factors and causes related to crowding that affect public service negatively. Based on the findings, evaluation indexes have been developed, and direction for improvement and problem resolution are presented based on a comparative analysis of six large railway stations at home and abroad. (Results) The study results show that crowding may be categorized as “density” or human crowding and “environmental congestion.” These classifications have physical and spatial aspects. In particular, environmental congestion causes negative feelings among space users, which may lead to avoidance of certain spaces. In addition, time oppression has more negative consequences when combined with crowding. In a space for movement, such as a railway station, crowd control directly affects public service. Public service elements that should be provided at a railway station include physical and psychological access, consistency (for sufficient understanding of the space), a pleasant atmosphere for engendering positive feelings among users, and safety resulting from openness and connectivity. These factors are affected by the correlation among public space components of a railway station such as transportation facilities, information facilities, safety/disaster (preventive) facilities, commercial facilities, and advertisement facilities. (Conclusions) The scope and categories of facilities need to be established to enhance intuitive recognition and minimize psychological confusion. Harmony with the surrounding environment should also be pursued by integrating items according to similarity of functions and elements and minimization of installation space. For efficient direction of human traffic in each functional area, zoning and traffic planning are also necessary. With clear standards that can be utilized not only in management and operations but also in design and construction, recovery of the proper functions and an elevation in the status of the railway station as a complex cultural space can be achieved.
