Purpose: To report cases of the surgical removal of sub-Tenon triamcinolone acetonide to control increased intraocular pressure after sub-Tenon triamcinolone acetonide injection Case summary: Three patients had no response to maximal medical treatment to control suddenly increased intraocular pressure after sub-Tenon triamcinolone acetonide (40 mg) injection to treat diabetic macular edema. The anterior chamber angle was open in all patients, and there was no neovascularization in the iris or anterior chamber angle. Slit lamp biomicroscopy showed deposition of triamcinolone acetonide in the inferior sub-Tenon area. Intraocular pressure was decreased within the normal range without any medication after removal of triamcinolone acetonide precipitates. Conclusions: Surgical removal of sub-Tenon triamcinolone acetonide can be as a primary treatment option in cases of increased intraocular pressure which shows no response to maximal medical treatment after sub-Tenon triamcinolone acetonide injection.

Purpose: To determine the risk factors for transient hypotony after silicone oil removal in rhegmatogenous retinal detachment and to analyze changes in intraocular pressure and visual acuity after silicone oil removal. Methods: The medical records of 54 eyes of 52 patients who underwent pars plana vitrectomy, silicone oil tamponade followed by silicone oil removal due to rhegmatogenous retinal detachment, were reviewed. Results: The incidence of transient hypotony after silicone oil removal was 18.5%. Young age (p = 0.011) and axial length (p = 0.002) were risk factors for transient hypotony based on univariate analysis. In multivariate analysis, axial length longer than 26 mm was the only risk factor for transient hypotony (p = 0.005). Seven hypotony patients recovered to normal intraocular pressure spontaneously within 2 weeks. In 2 patients, intraocular pressure was normalized after intravitreal injection of C3F8 gas and 1 patient recovered after a balanced salt solution injection into the anterior chamber. Two weeks after silicone oil removal, there was no significant difference in intraocular pressure between the hypotony group and normal intraocular pressure group. Additionally, there was no statistically significant difference in best corrected visual acuity between the 2 groups after 2 weeks. Conclusions: Although transient hypotony after silicone oil removal in rhegmatogenous retinal detachment was frequently observed in the present study, the final best corrected visual acuity and intraocular pressure was not always affected. Ocular hypotony should be examined thoroughly in the early postoperative period.

The objective of this study was to identify the correlations among service quality and service value, cognitive and emotional responses, customer satisfaction, revisit intentions and loyalty. The subjects are consisted of golf course users and data collection was conducted through convenience sampling. A total of 300 samples was collected, among which 286 samples were used the final analysis. The collected data was processed using SPSS 12.0 and AMOS 7,0 programs for path analysis to verify each hypothesis. The results of the analysis produced the following conclusions. First, service value was not influenced by the quality of golf course services, consisting of service assurance, reliability and utility, but service empathy and responsiveness were factors that did have a positive impact on service value. Secondly, the service value of golf courses had a positive effect on cognitive and affective responses and customer satisfaction. Thirdly, the users cognitive and emotional responses regarding golf courses had a positive impact on customer satisfaction. Fourthly, the customer satisfaction experienced by golf course users did have an influence on the users loyalty, but did not have any impact on their revisit intentions. Fifthly, golf course users revisit intentions had a positive correlation to their level of loyalty.

The purpose of this study was to investigate the influence of sports performance strategies on burnout and perceived performance of college athletes. Through convenience sampling method, selected 338 survey questionnaires were used for final analysis from college athletes. With the collected data, t-test, one-way ANOVA, and multiple regression analysis were performed by SPSS 18.0. The results of the analysis were summarized as follows. First, the gender, grade, type of athletes, and athletes career showed significantly difference on sports performance strategies, burnout, and perceived performance. Second, the relaxation impacts positively(+) influence on emotional exhaustion, and the control of condition and imagery and goal orientation impacts negatively(-), but emotional control positively(+) influence on depersonalization. Moreover, the self-talk, control of condition, imagery and goal orientation, and relaxation impacts positively(+) influence on reduced personal accomplishment. Third, the self-talk, control of condition, imagery and goal orientation, relaxation, and emotional control impacts positively(+) influence on perceived performance. Fourth, the emotional exhaustion and reduced personal accomplishment impacts positively(+), but depersonalization impacts negatively(-) influence on perceived performance.
