No full textPurpose: To report a case with ischemic macular edema (ME) due to an acute branch retinal vein occlusion (BRVO) which was treated with repeated intravitreal anti-VEGF injections. Methods: Retrospective case presentation. Results: A 66-year-old female patient was treated with repeated intravitreal anti-VEGF injections due to ischemic ME following an acute BRVO. Over a period of 2.5 years best corrected visual acuity increased from 0.06 to 0.6 (decimal notation) accompanied by a reduction in central retinal thickness from 546 to 292 µm. Overall 17 anti-VEGF injections were administered to treat repeated recurrence of ME. Macular ischemia did not worsen during this profound intravitreal anti-VEGF therapy. Conclusion: Intravitreal anti-VEGF therapy can be a beneficial treatment strategy even in ischemic ME following an acute BRVO

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Prevalence of Back Pain among German Ophthalmologists
No full text<jats:p>&lt;b&gt;&lt;i&gt;Introduction:&lt;/i&gt;&lt;/b&gt; The aim of this study was to evaluate the prevalence of back pain among German ophthalmologists, to investigate the relationship towards age, gender, various profession-related factors, to correlate localization of pain to subspecialties, and to explore individual therapeutic and coping strategies. &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; In this prospective, cross-sectional survey, a 9-item questionnaire was sent via mail to all members of the German professional association of ophthalmologists “Berufsverband der Augenärzte Deutschlands e.V. (BVA).” Responses were analyzed according to a pre-specified analysis plan. &lt;b&gt;&lt;i&gt;Results:&lt;/i&gt;&lt;/b&gt; From a total of 5,954 members contacted, 1,861 copies (31%) were received back, of which 1,807 (30%) were suitable for analysis. 913 (51%) participants were female and 876 (48%) were male, with a median age of 50 years (interquartile range: 44; 57). 1,464 ophthalmologists (81%) reported current back problems, considerably more than had been reported in the general population or in other medical specialties. Older age, female gender, and higher number of professional years appeared to be risk factors for developing back pain. Overall, neck pain was the leading symptom in 951 attendees (65%) but differed between ophthalmologists who primarily performed conservative treatment (cervical spine) and those who performed surgery (mainly lumbar spine). 1,037 participants (71%) link their complaints to their occupational activity. Exercising and back training were reported as common strategies for prevention and coping with the problem. Recommendations for improvement were mainly ergonomic optimization of the working place. &lt;b&gt;&lt;i&gt;Conclusions:&lt;/i&gt;&lt;/b&gt; The prevalence of back pain complaints in German ophthalmologists is high. Neck pain (65%) was the leading localization, followed by low back pain (53%) and shoulder (38%) problems, which might emphasize a special back pain complaint profile in ophthalmologists. Low back pain seems to be more common in ophthalmologists with surgical specialization than in those with mainly medical tasks. The high prevalence of back pain in ophthalmologists should be communicated with employers, the industry, and professional societies to develop and implement a strategy to prevent occupational-related musculoskeletal disorders and preserve the ability to work and the quality of life. </jats:p>
