Pars Plana Vitrectomy for Vitreomacular Traction Syndrome: Analysing the Preoperative Prognostic Factors

Purpose: To identify the prognostic factors affecting the surgical outcomes in patients with vitreomacular traction syndrome undergoing pars plana vitrectomy. Methods: This was a retrospective clinical study of 67 eyes of 67 patients with vitreomacular traction syndrome who underwent pars plana vitrectomy. Demographic, clinical, and optical coherence tomography (OCT) characteristics were collected and analyzed. Univariate and multivariate linear regression analysis were used to examine the effect of parameters on change in best-corrected visual acuity (BCVA). Results: At a mean follow-up period of 15.9±12 months (mean±SD), the BCVA improved from 0.7±0.3 LogMAR (mean±SD) to 0.5±0.3. Seven patients developed full-thickness macular hole intraoperatively and tamponade (air, 20% SF6 or 12% C3F8) was used in 41 patients. Retinal breaks were identified intraoperatively in four patients. Regression analysis demonstrated that the preoperative BCVA was the only parameter affecting the postoperative visual outcome. Conclusion: In the present study, the preoperative BCVA plays a predictive role in the surgical outcome of patients with VMT undergoing pars plana vitrectomy. No other preoperative OCT characteristics demonstrated prognostic potential. Further prospective studies are needed in order to examine the role of several factors that could potentially facilitate preoperative patient counselling. © Taylor & Francis

Leisure Motivation of Participants and Nonparticipants in Campus Recreational Sports Programs

The factors that motivate college students to participate in leisure activities play a key role in better understanding participation patterns in campus recreational sports. This study utilized the Leisure Motivation Scale developed by Beard and Ragheb (1983) to determine factors that motivated college students\u27 leisure choices. The purpose of this study was to examine motivational differences in students who participated regularly in campus recreational sports and students who did not regularly participate in campus recreational sports. The sample consisted of 631 students from two universities. The results indicated that students who did not participate regularly in campus recreational sports were seeking rewards from their leisure such as rest, escape and solitude, as well as the opportunity to use their imagination and learn. Students who regularly participated in campus recreational sports revealed that they were motivated to participate because of physical activity, challenge, and competition. In addition, differences in gender and overall motivation for leisure participation were examined

Motivation for Participation in Campus Recreation Based on Activity Type

In this study, we examined differences in leisure motivation on the basis of the type of campus recreational activity in which a student was engaged. Specifically, campus recreational activities included aquatics, group fitness, intramural sports, informal sports, and informal fitness. The Leisure Motivation Scale (Beard and Ragheb, 1983) was completed by subjects after they engaged in a campus recreation activity. A 95% confidence level was established a priori, but a Bonferroni adjustment resulted in α ≤ .0015. Results from an analysis of variance indicated differences between activity type. Subjects engaged in informal sports were less motivated by competency/mastery factors than those engaged in other campus recreation activities. In addition, stimulus avoidance was a less predominant motivator in subjects participating in intramural sports than in those involved in other types of programs. These results suggest that students engaged in different activities are motivated by different factors and have implications for campus recreation programmers and marketers as they design programs
