Purpose: To evaluate the clinical characteristics of bacterial culture, and visual outcome in patients with acute endophthalmitis. Methods: Clinical records of patients treated for acute endophthalmitis in GNUH from 2000 to 2009 were reviewed. The specimens for culture were obtained from the anterior chamber or vitreous. Clinical outcome measures were bacterial culture, culture rate, and final visual acuity. Results: Cultures (total 59 cases) showed bacterial growth in 37 cases (63%). Among 35 cases vitreous specimens, bacteria growth was found in 22 cases (63%), and from the 27 anterior chamber specimens, 12 cases (44%) were culture positive. From these 37 bacterial-positive cultures, 11 (30%) were coagulase negative Staphylococcus species, 16 (43.0%) were other Gram-positive species, 9 (24%) were Gram-negative species, and 1 (3%) produced a polymicrobial culture. Final visual acuity above 0.5 was achieved in 16 of 59 (27%) cases and coagulase negative <em>Staphylococcus</em> species had the greatest proportion being 5 of 11 (45%). Conclusions: The bacterial culture positivity rate in bacterial endophthalmitis was 63%, and the culture yield rate from the vitreous was higher than the anterior chamber aqueous samples. Coagulase negative <em>Staphylococcus</em> species were the most common causative organisms and showed the best final visual outcome in endophthalmitis. J Korean Ophthalmol Soc 2011;52(10):1173-1181
고등학교 생명 과학Ⅰ 교과서 ‘자연 속의 인간’ 단원 삽화 분석
이나은,김재근 한국현장과학교육학회 2014 현장과학교육 Vol.8 No.1
교과서의 삽화는 학생들에게 중요한 영향을 미치는 자료 중 하나이다. 이 연구에서는 생명 과학Ⅰ 교과서 ‘Ⅳ. 자연 속의 인간’ 단원의 삽화의 빈도,종류, 용도를 분석하였다. 제시된 삽화의 종류에 있어서는 ‘사진’이 49.3 %로 가장 많았고, ‘그림’과 ‘그래프’가 다수 사용되었다. 삽화가 사용된 주된용도는 과학 개념을 학습자에게 이해시키기 위한 ‘자료 제공2’가 가장 많았고, 이어 ‘동기 유발’, ‘자료 제공1’을 위해 사용되었다. 삽화의 종류에 따라사용된 용도를 분석한 결과, ‘사진’의 경우에는 주로 ‘동기 유발’과 ‘자료 제공’의 용도로 사용되었고, ‘그림’, ‘그래프’ 등 나머지 삽화 종류는 주로 ‘자료제공’의 용도로 사용되었다. 삽화의 빈도에 관한 연구 결과는 기존의 연구와 유사하였으나, ‘Ⅳ. 자연 속의 인간’ 단원은 다양한 요소 간의 관계를 요구하는 분량이 많아 여타 과목보다 많은 그래프 자료를 활용하였다. 학습자가 이해하기 쉽고 재미있으며 활용하기 편한 구성의 교과서를 제공하기 위해서는실험에 사용되는 삽화의 수와 실험의 수를 늘려야 한다. 교과 내용에 흥미를 갖고 이해하도록 하기 위해 상황에 맞는 다양한 삽화를 도입해야 한다. Illustrations in text books are the most influential material tostudents. So we have to analyze illustrations in text books. Inthis study, the number, sort, purposes of illustrations in the Unit‘The Human in the nature’ of highschool Life Science textbookswas analyzed. The sort consists of ‘photograph (49.3 %)’ andmany of ‘drawings’ and ‘graphs’. The main purpose ofillustrations is for ‘providing materials 2’, followed by‘motivation’, ‘providing materials 1’. According to the analysis ofthe purpose depending on the sort, ‘photograph’ is mainly usedfor ‘motivation’, ‘providing materials’, other illustrations like‘drawing’ and ‘graph’ are mainly used for ‘providing materials’. The result of this study was very similar to existing studies, butthere are some differences in ‘graph’. The Unit ‘The Human inthe nature’ uses more graphs than any other subjects becauseit contains connections between various factors. For providingunderstandable and easily usable textbook, we have to increasethe number of illustrations used for experiments. And we needmore various illustrations that suit the learning situations for motivating students effectively.

Purpose: To report the case of a child with triple X syndrome presenting with exotropia and chorioretinal coloboma. Case summary: A one-year-old female infant presented with 35PD exotropia in the primary position. The patient had poor fixation of the right eye, and a fundus examination showed chorioretinal coloboma in the inferior region of her right eye. The patient also exhibited syndactyly of the right hand. Brain magnetic resonance imaging revealed a well-defined 2 cm cyst in the right cerebellum. Upon chromosomal study, the patient’s karyotype was found to be 47, XXX. Conclusions: When infants or children present with ophthalmologic findings such as strabismus and coloboma, systemic conditions and congenital problems should be considered. 목적: 47, XXX로 염색체 이상을 보이는 환자에서 외사시와 맥락망막결손증이 동반된 증례를 경험하였기에 이를 보고하고자 한다. 증례요약: 1세된 여자 환아가 외사시를 주소로 내원하였다. 제일 눈위치에서 35PD의 외사시를 보였으며 우안 주시가 잘 되지 않았고 안저 검사상 우안 아래측에 맥락망막결손이 관찰되었다. 전신검사상 오른손에 합지증을 동반하고 있었고 뇌 자기공명영상에서 우측 소뇌에 낭이 관찰되었다. 염색체검사를 실시한 결과에서 47, XXX 증후군으로 밝혀졌다. 결론: 사시환자의 검사시 전신질환 및 선천 질환의 동반 여부를 확인해야 할 것이다.

Purpose: To compare the surgical results of trabeculectomy and Ahmed glaucoma valve implantation after a previous failed trabeculectomy. Methods: A retrospective comparative case series review was performed on 31 eye surgeries in 20 patients with primary congenital glaucoma who underwent trabeculectomy or Ahmed glaucoma valve implantation after a previous failed trabeculectomy with mitomycin C. Results: The preoperative mean intraocular pressure was 25.5 mmHg in the trabeculectomy group and 26.9 mmHg in the Ahmed glaucoma valve implantation group (p = 0.73). The 48-month postoperative mean intraocular pressure was 19.6 mmHg in the trabeculectomy group and 20.2 mmHg in the Ahmed glaucoma valve implantation group (p = 0.95). The 12-month trabeculectomy success rate was 69%, compared with 64% for Ahmed glaucoma valve implantation, and the 48-month success rates were 42% and 36% for trabeculectomy and valve implantation, respectively. The success rates following the entire follow-up period were not significantly different between the two groups (p > 0.05 by log rank test). Postoperative complications occurred in 25% of the trabeculectomy-operated eyes and 9% of the Ahmed-implanted eyes (p = 0.38). Conclusions: There was no significant difference in surgical outcome between the trabeculectomy and Ahmed glaucoma valve implantation groups, neither of which had favorable results. However, the trabeculectomy group demonstrated a higher prevalence of adverse complications such as post-operative endophthalmitis.
