Attention and altmetrics

Abstract Introduction: The concept of attention is applied in two altmetric studies concerning: (1) the use of social media tools on the web pages of scientific journals, and indications of attention in these pages received, and (2) attention received by the radio news on the web page of an indigenous radio station. The purpose is to reveal characteristics of web publications connected to the attention they receive. Method: Altmetric data describing attention data was compiled from the Facebook sites of scientific journals and the Facebook pages of an indigenous radio station news programme, as well as the news programme’s web site. The study was both quantitative and qualitative. Analysis: Attention was operationalized in the form of comments, likes or sharing of Facebook postings and these were analyzed quantitatively. The contents of the postings were analysed by qualitative content analysis. Results: The characteristics of the postings receiving most attention were relevance, community (in the sense of ownership), belonging and co-creation, and engagement in the meaning of interactivity. Conclusions: In altmetric research, data originating from several sources can reflect the societal impact a project or a publication may have, not only the impact it has in science. Attention economy theory supports the interpretation of altmetric data

Epiretinal Membrane and Cystoid Macular Edema after Retinal Detachment Repair with Small-Gauge Pars Plana Vitrectomy

To evaluate the incidence rates of cystoid macular edema (CME) and epiretinal membrane (ERM) formation after uncomplicated primary 23-G and 25-G retinal detachment (RD) repair and to identify risk factors associated with postoperative CME and ERM formation. This was a consecutive interventional case series of 587 eyes that underwent one RD repair with 23-G or 25-G pars plana vitrectomy (PPV) with scleral buckling. Epiretinal membrane and CME were confirmed by optical coherence tomography (OCT) and fluorescein angiography (FA). A total of 587 eyes with a mean follow-up of 404 days had incidence rates of 35.1% for ERM and 15.2% for CME. The incidence of ERM after combined PPV and scleral buckling (48.4%) (n = 61) was greater (p<0.0001) compared to that after PPV alone (31.2%) (n = 144). Epiretinal membrane and CME develop frequently after small-gauge RD repair. Pars plana vitrectomy combined with scleral buckling is associated with a higher incidence of ERM. Patients might benefit from increased use of OCT and FA to help rule out CME/ERM
