RESUMO
We report on our experience with the intra-arterial administration of eptifibatide for thrombolysis during aneurysm-embolization procedures. In 4 cases (3 stent-assisted coiling procedures and 1 with posthemorrhagic vasospasm), we noted the formation of thrombus occluding a vessel. We administered eptifibatide (10-15 mg) through a microcatheter proximal to the thrombus. The thrombus rapidly dissolved, resulting in the recanalization of the occluded vessels with no rethrombosis or hemorrhagic complications.

PURPOSE: To assess the prevalence of astigmatism in a sample of 1738 students (15-18 years old) from Northern Greece. METHODS: Collection of the sample was based on a questionnaire method. Statistical analysis included estimation of the prevalence of astigmatism and the distribution of students according to their cylindrical values. We also checked whether heredity or sex affected the occurrence of astigmatism. RESULTS: The prevalence of astigmatism was 10.2%. It was mostly at low levels, up to 2 D cyl. Females ran a significantly higher risk of astigmatism than males, and heredity seemed to be an important predisposing factor for this refractive error. CONCLUSIONS: There is considerable variability in the prevalence of astigmatism worldwide, as indicated by different studies. However, this refractive error prevails at low levels in the Greek student population, compared with other countries.

PURPOSE: An epidemiological study, concerning the prevalence of myopia among the student population (15-18 years old) of Northern Greece, was carried out. METHODS: Specific questionnaires were used in order to collect data on the refractive condition of students. RESULTS: Myopia prevalence was 36.8% and was found to be more common in females (46.0%) than in males (29.7%). The prevalence increased in students with myopic parents and myopic siblings. It was also found that myopia correlates strongly with nearwork and school performance. CONCLUSION: The study results suggest that myopia is a rather common refractive error in Greek students. Findings also indicate that myopia is probably hereditary and correlates with educational level, intelligence and excessive nearwork.
