Purpose: To investigate correlations among the cup-to-disc ratio (CDR), intraocular pressure (IOP), and the occlusion site in branch retinal vein occlusion (BRVO). Methods: This prospective study involved 62 eyes with a diagnosis of BRVO. Fundus photography, fluorescein angiography, Goldmann applanation tonometry, and optical coherence tomography were performed. Correlations among CDR, IOP, and the occlusion site were analyzed. Results: A negative correlation was found between the occlusion site and IOP (p<0.001, Pearson’s correlation analysis) and between the occlusion site and CDR (p<0.001, Pearson’s correlation analysis). However, the correlation between IOP and CDR was poor (p=0.092, Pearson’s correlation analysis). Conclusions: BRVOs with an occlusion site near the optic disc are associated with raised IOP and CDR values. This study suggests that the occurrence of BRVO with an occlusion site near the optic disc indicates that the patient should be evaluated for glaucoma. J Korean Ophthalmol Soc 49(7):1094-1100, 2008

Purpose: The author evaluated the impact of vitreoretinal surgery for proliferative diabetic retinopathy (PDR) on bilateral visual function. Methods: Anatomic and visual acuity outcomes were reviewed by author for patients who underwent bilateral surgery for PDR. Bilateral visual function was evaluated using the American Medical Association (AMA) Guidelines for Disability scale to quantitate the impact of surgery on visual system disability. Results: There were 18 patients (36 eyes) who underwent vitrectomy for complications of PDR, and the overall anatomic success rate was 100%. Mean visual impairment of the study eyes and visual system according to AMA Guidelines for Disability decreased postoperatively by 22.4% points, and 25.7% points, respectively. A higher functional level of the bilateral visual system resulted postoperatively in 83.2% of all patients, according to eyes with better visual acuity. Conclusions: Vitreoretinal surgery was associated with a reduction in bilateral visual disability and improved bilateral visual function in patients with PDR.

The purpose of this study was to examine the relationships among leisure sports participation, wellness inventory and life satisfaction, The subjects were 645 adults(male=348; female=297) aged more than 20 years who participated in community-based leisure sports programs of the fitness clubs in Seoul and Incheon City, Korea, The degree of leisure sports participation; items on the Wellness scale developed and used by Kim Sang-kuk based on Wellness: Concepts and Application developed by Anspaugh et al.(l994); and the Korean version of the Satisfaction with Life scale(SWLS) developed by Diener, Emons, Larsen & Griffin(1985) translated and used by Lee Jong-kil(1992). The validity of the questionnaire was verified through specialists' meeting, the pilot test, and exploratory and confirmatory factor analysis. The reliability of the questionnaire was found to be Cronbach' s α=.66~.83. The methods of statistics used to analyze the collected data were correlation analysis and multiple regression using SPSS WIN 11.5. As a result, the following findings were obtained: First, it was found that the degree of leisure sports participation had an effect on the wellness inventory. That is, participants who participated in the leisure sports program longer, more frequently, and more actively had the higher level of recognition on the wellness inventory than any other group. Second, it was found that the degree of leisure sports participation had an effect on the life satisfaction. That is, participants who participated in the leisure sports program longer, more frequently, and more actively the higher level of recognition on the life satisfaction than any other group. Third, it was found that the wellness inventory had an effect on the life satisfaction. That is, the participants who were highly conscious of physical, social, mental health domains as subfactors of the wellness inventory had the higher level of life satisfaction.

유두앞혈관고리와 관련하여 발생한 망막분지동맥폐쇄와 유리체출혈 1예

Purpose: To report a case of prepapillary loops (PPLs) associated with branch retinal artery occlusion (BRAO) and vitreous hemorrhage in a patient with IgA nephropathy. Methods: A 26-year-old woman presented with sudden loss of vision in her right eye. One year prior, she had been diagnosed as having IgA nephropathy. Examination of the right fundus revealed vitreous hemorrhage that appeared to be extending from the optic disc and a pale and edematous superior retina that was compatible with BRAO. Subretinal and intraretinal hemorrhage extending from the optic disc were also present. Laboratory tests of the factors associated with coagulation were normal. Results: After spontaneous resolution of the vitreous hemorrhage and retinal edema, arterial PPLs and a venous PPL were detected at the superior portion of the optic disc. Fluorescein angiogram demonstrated slow filling of the superior branch of the retinal veins and the venous PPL. The filling of the arterial PPLs was normal and there was no delayed perfusion in the superior retina. These PPLs did not show any fluorescein leakage in the late phase of the angiogram. At the last follow-up visit, 18 months after the onset of symptoms, the vitreous hemorrhage and subretinal hemorrhage had been completely absorbed and no other ocular complications hd developed. Conclusions: PPL is usually asymptomatic; however, complications such as BRAO and vitreous hemorrhage can develop in some cases with causative factors.

The purpose of this study was to identify the effect of non-verbal communication on the instructor’s evaluation and the intention to continuance of exercise in the private golf schools. To conduct this study, the inventory of non verbal communication(Sundaram & Webster, 2000), the instrument of instructor’s evaluation(Hu Een Sook, 2008), and the inventory of intention to continuity of exercise (Lee Young Hee, 2006) were used in this investigation. 213 subjects were selected from Kyungki-do and the Seoul metropolitan area. Collected data were analyzed by frequency, reliability, correlation, confirmatory factor and structural equation modeling (SEM). The results were as follows: First, the non-verbal communication does effect positively in instructor’s evaluation. The second, there were no correlation between non-verbal communication and the intention of continuity to exercise. Finally, the instructors’ evaluation does effect positively in intention of their continuity.

림프종증은 20세 이전, 주로 소아에 발생하는 매우 드문 질환으로 주로 골, 연부 조직, 내부 장기에 발생하는 미만성 림프관 증식성 병변이다. 대부분의 경우 골 조직 및 내장 실질을 침범해서 병적 골절, 유미 흉, 유미 복수, 유미 심낭액, 침범된 내부 장기에 의한 급성 증상을 나타낸다. 저자는 유미 흉과 다발성 골 용해 병변을 동반한 림프종증 2예를 경험하였으며 유미 흉에 대해서 흉관 삽입 배액술 및 화학적 흉막 유합술을 시행하였다. 1예는 골 용해 병변이 우측 견갑골에 국한되었으며 상완골에는 성장 정지가 동반되어 Ilizarov 기구를 이용한 골 연장술을 시행하였다. 나머지 1예는 우측의 경골, 대퇴골, 상완골, 견갑골과 좌측의 대퇴골과 상완골에 골 용해 병변이 있었으며 특히 우측의 대퇴골과 경골은 골 용해, 골 경화, 병적 골절, 가관절증 등이 아주 심해 체중 부하가 불가능한 상태였으며 좌측 대퇴골에서는 병적 골절 예방을 위해 골수정으로 내고정술을 시행하였다. Lymphangiomatosis is a rare disorder that occurs mainly in children or during the first two decades of life. It is characterized by a diffuse proliferation of lymphatic channels involving the bones, visceral parenchyma, and soft tissue. Most cases of lymphangiomatosis have bone and visceral involvement and usually present with chylothorax, chylous ascites, chylous pericardial effusion, or acute symptoms that are related to the affected organs. The authors experienced two cases that presented with chylothorax and multiple lytic bone lesions. Chest drainage and chemical pleurodesis were performed for treatment of the chylothorax. In one case, lytic bone lesions were found only in the right scapula and bone lengthening with an Ilizarov frame was performed for growth arrest in the right humerus. In the other case, lytic bone lesions were found in both femurs and both humeri, the right tibia, and the right scapula; and were particularly severe in the right tibia and femur. The lytic bone lesion, osteosclerosis, pathologic fracture, and pseudoarthrosis were so severe that weight-bearing was impossible. Internal fixation was performed with an intramedullary nail in the left femur.
