[Ophthalmologic publications from Germany].
BACKGROUND
The German contribution to the worldwide publication activity in ophthalmology had not yet been explored properly.


METHODS
A quantitative bibliometric analysis of ophthalmologic publications for the years 1993-2007 was performed using the online database of the Institute for Scientific Information (ISI). The analysis used eight selected search words as well as publication activities of 45 journals in the ISI category "ophthalmology."


RESULTS
The analysis according to search words revealed a proportion of 9.9% for ophthalmologic publications from Germany and a proportion of 8.9% according to journal-specific publication activities. The contribution of publications from Germany in English-language journals was 5.9%. Approximately two-thirds of the German publications were written in English and one-third in German. Germany ranked second behind the United States in absolute publication numbers but was behind other Anglo-Saxon and Scandinavian countries when the numbers were adjusted for population size.


CONCLUSIONS
German ophthalmologic publications have reached an appreciable level in the international literature.
