All manuscripts are subject to editorial review.
Manuscripts are received with the explicit understanding that they are not under simultaneous consideration by any other publication.
A cover letter with the name, address, and telephone and telefax numbers of the corresponding author must accompany each manuscript. This letter must include a statement that affirms that all authors
concur with the submission.
Submission of an article for publication implies transfer of the copyright from the author to the publisher upon acceptance. Accepted papers become the permanent property of 'Ophthalmologica'; and
may not be reproduced by any means, in whole or in part, without the written consent of the publisher.
It is the author's responsibility to obtain permission to reproduce illustrations, tables, etc. from other publications.
Conflicts of Interest
Authors are required to disclose any sponsorship or funding arrangements relating to their research and all authors should disclose any possible conflicts of interest. Conflict of interest statements
will be published at the end of the article.
Published research must comply with the guidelines for human studies and animal welfare regulations. Authors should state that subjects have given their informed consent and that the study protocol
has been approved by the institute's committee on human research. Further, they should also state that animal experiments conform to institutional standards.
Whether intentional or not, plagiarism is a serious violation. We define plagiarism as a case in which a paper reproduces another work with at least 25% similarity and without citation.
If evidence of plagiarism is found before/after acceptance or after publication of the paper, the author will be offered a chance for rebuttal. If the arguments are not found to be satisfactory,
the manuscript will be retracted and the author sanctioned from publishing papers for a period to be determined by the responsible Editor(s).

Digital Object Identifier (DOI)
S. Karger Publishers supports DOIs as unique identifiers for articles. A DOI number will be printed on the title page of each article. DOIs can be useful in the future for identifying and citing articles
published online without volume or issue information. More information can be found at www.doi.org
Supplementary material is restricted to additional data that are not necessary for the scientific integrity and conclusions of the paper. Please note that all supplementary files will undergo editorial review
and should be submitted together with the original manuscript. The Editors reserve the right to limit the scope and length of the supplementary material. Supplementary material must meet production quality
standards for Web publication without the need for any modification or editing. In general, supplementary files should not exceed 10 MB in size. All figures and tables should have titles and legends and all
files should be supplied separately and named clearly. Acceptable files and formats are: Word or PDF files, Excel spreadsheets (only if the data cannot be converted properly to a PDF file), and video files

The U.S. National Institutes of Health (NIH) mandates under the NIH Public Access Policy that final, peer-reviewed manuscripts appear in its digital
database within 12 months of the official publication date. As a service to authors, Karger submits your manuscript on your behalf to PubMed Central (PMC) immediately upon publication. It usually receives
a PMCID within approximately a month and will appear in PMC after 12 months. For those selecting our premium
service, the usual embargo will be overridden, accelerating the accessibility of your work. More

met: Articles may not be used for commercial purposes, must be linked to the publisher's version, and must acknowledge the publisher's copyright. Authors selecting Karger's
feature, however, are also permitted to archive the final, published version of their article,
which includes copyediting and design improvements as well as citation links.
There are no page charges for papers of 3 or fewer printed pages (including tables, illustrations and references). Each additional complete or partial page is charged to the author at CHF 325.00. The
allotted size of a paper is equal to approx. 8 manuscript pages (including tables, illustrations and references).
Unless indicated otherwise, proofs are sent to the corresponding author and should be returned with the least possible delay. Alterations other than the correction of printer's errors are charged to the
