Socio-economic deprivation and visual acuity at presentation in exudative age-related macular degeneration

Aim: To evaluate the influence of socio-economic factors on visual acuity (VA) at presentation in exudative age- related macular degeneration (AMD). Methods: The medical records of all consecutive patients with newly diagnosed exudative AMD examined at the Ophthalmology Departments of Grampian University Hospitals-NHS Trust, Aberdeen, and Gartnavel General Hospital, Glasgow, between July 2004 and June 2005, were reviewed. Demographics, duration of symptoms, VA in study and fellow eye, exudative AMD characteristics, status of fellow eye and patient home address, used to determine the Scottish Index of Multiple Deprivation (SIMD) score, were recorded. The effect of these parameters on VA at presentation was investigated using general linear modelling. Results: Two-hundred and forty patients (median age 79 years) were included in this study; 44 (18.3%) belonged to the lowest 20% SIMD score (most deprived). Age and location and type of the choroidal neovascular- isation were statistically significantly associated with VA at presentation (p = 0.003, p

Classification of fundus autofluorescence patterns in early age-related macular disease

PURPOSE. To describe and classify patterns of abnormal fundus autofluorescence (FAF) in eyes with early nonexudative age-related macular disease (AMD). METHODS. FAF images were recorded in eyes with early AMD by confocal scanning laser ophthalmoscopy (cSLO) with excitation at 488 nm (argon or OPSL laser) and emission above 500 or 521 nm (barrier filter). A standardized protocol for image acquisition and generation of mean images after automated alignment was applied, and routine fundus photographs were obtained. FAF images were classified by two independent observers. The ? statistic was applied to assess intra- and interobserver variability. RESULTS. Alterations in FAF were classified into eight phenotypic patterns including normal, minimal change, focal increased, patchy, linear, lacelike, reticular, and speckled. Areas with abnormal increased or decreased FAF signals may or may not have corresponded to funduscopically visible alterations. For intraobserver variability, ? of observer I was 0.80 (95% confidence interval [CI]0.71-0.89) and of observer II, 0.74. (95% CI, 0.64-0.84). For interobserver variability, ? was 0.77 (95% CI, 0.67-0.87). CONCLUSIONS. Various phenotypic patterns of abnormal FAF can be identified with cSLO imaging. Distinct patterns may reflect heterogeneity at a cellular and molecular level in contrast to a nonspecific aging process. The results indicate that the classification system yields a relatively high degree of intra- and interobserver agreement. It may be applicable for determination of novel prognostic determinants in longitudinal natural history studies, for identification of genetic risk factors, and for monitoring of future therapeutic interventions to slow the progression of early AMD.

External beam radiotherapy in exudative age-related macular degeneration: a pooled analysis of phase I data

In recent years external beam radiotherapy (EBRT) has been proposed as a treatment for the wet form of age-related macular degeneration (AMD) where choroidal neovascularization (CNV) is the hallmark. While the majority of pilot (Phase I) studies have reported encouraging results, a few have found no benefit, i.e. EBRT was not found to result in either improvement or stabilization of visual acuity of the treated eye. The natural history of visual loss in untreated CNV of AMD is highly variable. Loss of vision is influenced mainly by the presenting acuity, and size and composition of the lesion, and to a lesser extent by a variety of other factors. Thus the variable outcome reported by the small Phase I studies of EBRT published to date may simply reflect the variation in baseline factors. We therefore obtained information on 409 patients treated with EBRT from eight independent centres, which included details of visual acuity at baseline and at subsequent follow-up visits. Analysis of the data showed that 22.5% and 14.9% of EBRT-treated eyes developed moderate and severe loss of vision, respectively, during an average follow-up of 13 months. Initial visual acuity, which explained 20.5% of the variation in visual loss, was the most important baseline factor studied. Statistically significant differences in loss of vision were observed between centres, after considering the effects of case mix factors. Comparisons with historical data suggested that while moderate visual loss was similar to that of the natural history of the disease, the likelihood of suffering severe visual loss was halved. However, the benefit in terms of maintained/improved vision in the treated eye was modest.

Violence and social memory in twentieth century Belfast:Stories of Buck Alec Robinson

This article explores the life and commemoration of Buck Alec Robinson. A feared loyalist killer in 1920s Belfast, in more recent times he has featured as a lion-keeping “character” on wall murals and in tourist guide books. Robinson is employed as a case study to investigate two separate but, in this case, interlinked historiographical debates. The first involves Norbert Elias’s analysis of the decline of violence. The second relates to discussion of the analysis of social memory in working class communities, with violence being placed therein. The article supports historical assessments suggesting that the “civilizing offensive” had an uneven impact. That point is usually made in the context of working class men. This article extends it to political elites in Belfast and probes their flirtations with violent hard men. The case is made that it is a mistake to assume the “civilizing” dynamic is to be understood as a teleological or top-down process.

Will VEGF Trap-Eye reduce the treatment burden in neovascular age-related macular degeneration?

Evaluation of: Brown DM, Heier JS, Ciulla T et al. Primary end point results of a Phase II study of vascular endothelial growth factor trap-eye in wet age-related macular degeneration. Ophthalmology 118(6), 1089-1097 (2011); Heier JS, Boyer D, Nguyen QD et al. The 1-year results of CLEAR-IT 2, a Phase 2 study of vascular endothelial growth factor trap-eye dosed as-needed after 12-week fixed dosing. Ophthalmology 118(6), 1098-1106 (2011). Age-related macular degeneration is the most common cause of blindness in older adults in western countries, and is likely to become the largest cause of irreversible sight loss in the developing world. Treatments such as ranibizumab and bevacizumab that inhibit VEGF have improved visual outcomes markedly. Controlled trials and clinical experience have shown that the best outcomes are achieved when monthly treatment has been administered over 2 years. This poses a significant burden on health providers and patients. A novel inhibitor of VEGF, VEGF Trap-Eye, which allows less frequent dosing without loss of efficacy, has emerged as a potential treatment. CLEAR-IT 2 was a prospective randomized Phase II trial designed to assess the safety, tolerability and the anatomic and visual effects of repeated treatments with a range of doses of VEGF Trap-Eye. Impressive anatomic and visual improvements were noted with no safety concerns. © 2011 Expert Reviews Ltd.

Narratives of Spatial Division: The Role of Social Memory in Shaping Urban Space in Belfast

The paper examines the role of shared spaces in divided cities in promoting future sustainable communities and spaces described as inclusive to all. It addresses the current challenges that prevent such inclusiveness and suggests future trends of its development to be of benefit to the wider city community. It explains how spaces in divided cities are carved up into perceived ownerships and territorialized areas, which increases tension on the shared space between territories; the control of which can often lead to inter-community disputes. The paper reports that common shared space in-between conflicting communities takes on increased importance since the nature of the conflict places emphasis on communities’ confidence, politically and socially, while also highlighting the necessity for confidence in inclusion and feeling secure in the public domain. In order to achieve sustainable environments, strategies to promote shared spaces require further focus on the significance of everyday dynamics as essential aspects for future integration and conflict resolution.

The executive committee of the Greek Professional Association of Social Work in an age of austerity: examining its response

This paper explores the response by the Greek Association of Social Workers (SKLE) to Greece's current economic crisis. Socioeconomic conditions in Greece have deteriorated rapidly since the imposition of a Structural Adjustment Programme as a condition of the loan Troika provided to Greece to address its class-based public debt crisis. Interviews were conducted with SKLE Executive Committee members to examine SKLE's response in the context of newly raised inequalities. Research results show that SKLE recognised the negative consequences to both service users and its members. However, SKLE continues to reformulate its strategy mostly as a social partner. SKLE's previous strategy entailed amongst other things the analysis of policy proposals and participation in welfare related government committees. This strategy is no longer relevant because decision-making powers have been transferred to transnational bodies. This paper elaborates on these findings and discusses the barriers that prohibit SKLE from differentiation of its strategy. Although the research is country specific, it has implications for the broader global debate because professional associations must reformulate their strategies for better serving of both their constituents and the collective good based on the social justice mandate of the profession.
