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.

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.

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

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.

공막돌륭술 후 지속된 망막박리에 대한 기체망막유착술의 임상적 효과

김상국(Sang Kook Kim) 대한검안학회 2006 Annals of optometry and contact lens Vol.5 No.1

목적: 공막돌륭술 후 지속된 망막박리에 대해 시행한 기체망막유착술의 효과 및 문제점을 알아보고자 하였다. 대상과 방법: 단순 열공망막박리에 대해 공막돌륭술을 시행받은 후 망막열공의 지속적인 개방으로 인해 망막의 재유착에 실패한 환자들 중에서 기체망막유착술을 시행한 환자들을 대상으로 하였다. 기체망막유착술 후 망막의 재유착에 실패한 환자들에 대해 실패의 원인을 분석하였으며, 안저소견을 기술하였다. 결과: 기체망막유착술을 시행한 20안 중 9안에서 망막의 재유착에 실패하였다. 실패한 원인을 보면 9안 중 7안은 기체망막유착술과 관련되어 발생한 새로운 망막열공에 의해 망막박리가 재발한 경우였으며, 나머지 2안은 강한 견인력의 지속으로 인해 기체망막유착술로는 망막열공의 폐쇄가 불가능한 경우였다. 그리고, 기체망막유착술 후 새로운 망막열공이 발생한 눈에서 격자변성이 유의하게 많이 발견되었다. 결론: 격자변성과 같은 유리체망막유착을 동반한 경우 기체망막유착술에 의해 새로운 망막열공이 발생할 수 있다. 따라서, 공막돌륭술 후 망막의 재유착에 실패한 경우, 환자선택을 신중히 하고 적절한 수술방법을 선택함으로써 추가적인 수술의 빈도를 줄이고 조기에 망막을 재유착시킬 수 있을 것으로 생각한다. Purpose: The author evaluated the effects and problems of pneumatic retinopexy (PR) for persistent retinal detachment after scleral buckling surgery. Methods: A retrospective chart review was done for patients who underwent PR for persistent retinal detachment due to persistent opening of retinal tears after scleral buckling surgery. The author analysed the reasons for failure of retinal reattachment, and described the fundus findings of these patients. Results: PR failed to achieve permanent retinal reattachment in 9 of the 20 eyes. Of these 9 eyes, retinal redetachment occurred after PR by the development of a new retinal tear in 7 eyes, and by the persistent opening of an original retinal tear with continuous residual vitreous traction in 2 eyes. And lattice degenerations were observed more frequently in the eyes that developed new retinal tears after PR. Conclusions: PR can cause new retinal tears to occur in the eyes with vitreoretinal adhesions such as lattice degenerations. Therefore, in the cases of failed scleral bucking surgery, number of reoperations can be reduced and early retinal reattachment can be achieved by careful patient selections and appropriate surgical procedures.
