Visual fields in patients who have undergone vitrectomy for complications of diabetic retinopathy. A prospective study
BACKROUND: To determine the extent of visual field loss in patients who had required a pars plana vitrectomy secondary to complications of proliferative diabetic retinopathy. METHODS: Patients that had undergone a vitrectomy on at least one eye for treatment of either vitreous haemorrhage or tractional retinal detachment were selected for study. ETDRS acuity and Humphrey binocular Esterman visual field testing were performed and compared to the minimum standards for safe driving as defined by the Royal College of Ophthalmologists in 1999. In addition to this Goldman kinetic visual fields using a III4e and V4e stimulus size and central 24-2 threshold test with the SITA-fast strategy were performed on the vitrectomised eye. RESULTS: 20 patients (n = 20) were recruited. Mean visual acuity in the eye being tested was 0.20 (Snellen 6/9.5). Results from the Humphrey field analyzer showed a mean number of abnormal stimulus locations of 71.2% (p < 0.005). 70% of patients had sufficient binocular acuity to drive and of these 71.4% were shown not to have a minimum visual field for safe driving on binocular Esterman field analysis. CONCLUSION: Vitrectomy potentially allows retention/restoration of good visual acuity in patients with complications of proliferative diabetic retinopathy. However patients may be suffering from unrecognized visual impairment consequent upon extensive visual field loss which in over two thirds of patients may be sufficiently severe to preclude safe driving

The social selectivity of certain sports with regard to German migrants theoretical reflections using handball as an example
Borggrefe C, Cachay K. The social selectivity of certain sports with regard to German migrants theoretical reflections using handball as an example. EUROPEAN JOURNAL FOR SPORT AND SOCIETY. 2018;15(3):250-267.In Germany, sports like football, weightlifting and boxing, practised by many sportsmen and women with a migrant background, stand in stark contrast with sports rarely taken up by the migrant population. Among the latter is handball, undoubtedly the second most popular German team sport after football. This paper addresses the problem of social selectivity in handball with regard to migrants in Germany and aims at identifying possible causes of this lack of participation on the basis of theoretical reflections. In concrete terms, the objective is to develop a theoretical model in which all exclusion mechanisms contributing to the social barriers facing people with a migrant background in handball are collated
