ORIGINAL PAPERS

Arrangement of the manuscript: The manuscript should include the following: 1) title page; 2) abstract, and key words; 3) main text (introduction, materials and methods, results, discussion); 4) acknowledgement; 5) references; 6) figure and figure legends; 7) tables; 8) illustrations and graphics. For more information on manuscript format, please refer to the following guidelines.

1) The Title Page should contain on separate lines author(s) name, institution, and the title of the article. In addition it should contain the e-mail and postal addresses, plus telephone and fax numbers of the corresponding author. All author affiliations and corresponding authors addresses should be supplied in English.

2) The Abstract of original papers must be structured with the following headings: Purpose, Methods, Results, Conclusion, and should not exceed 250 words. Abstracts of review articles, perspective of ophthalmology, historical articles, case reports and case series do not have to be structured in this same way. Diagnosis/Therapy in Ophthalmology contributions, editorials and Letters to the Editor do not have an abstract, please see separate instructions below. Key Words: Four to nine key words for indexing purposes must be given.

3) Main text should be concise and as far as possible free of specialised language, and unnecessary or not generally accepted abbreviations. Abbreviations must be spelled out on first mention.
The following order of presentation is recommended:
Introduction stating the purpose of the article and key aspects of present knowledge. Extensive literature reviews are not desirable. Primary sources are preferred.
Material: Notice that the journal requests that all research has followed the Tenets of the Declaration of Helsinki, and that the details are provided in the manuscript text. Methods of investigation with sufficient information to permit repetition of experiments. The journal requires that authors who report on eye cancer include in their manuscript the Union for International Cancer Control / American Joint Committee on Cancer (UICC / AJCC) Tumor, Node, Metastasis (TNM) categories and stages (7th Edition) in addition to any other cancer classification scheme the authors wish to use.

Statistics and mathematical analyses should be applied when appropriate and be described under Methods. Authors are encouraged to take advice from an expert of statistics already when the study is designed. The following rules regarding reporting should be adhered to:
- Report proportions if the number of subjects is smaller than 10 (e.g. 2 of 5), report percentages in integers if the number of subjects is less than 100 (e.g. 34%). If the number of subjects is larger, one decimal place can be given, but is seldom necessary (e.g. 34.5%).
- Report summary statistics of normally distributed variables as mean with standard deviation, and other variable as medium with range. Use parametric and nonparametric statistical tests accordingly.
- Give exact p-values (e.g. p=0.15 and p=0.034); if p-value is smaller than 0.0001, report p - Give 95% confidence intervals for main findings.
- Mention the statistical test used with the p-value (e.g. p=0.015, paird t-test). If the same test is repeated, it does not need to be specified again.
- The statistical software used need not be referenced in the manuscript text, unless it is specific for the statistical method used (or these can be put later under a separate heading, with a pointer here).
Results should be as clearly presented as possible. Scatterplots and similar graphical presentations are often preferable to tables. Do not duplicate in the text data that is given in tables and figures.
Discussion should be based directly on the author(s)' contributions and with reference to prior investigations, pointing out the significance and the limitations of the study.

4) Acknowledgements should indicate the name, society and date of the meeting if an abstract of the article has been presented previously. Support for the study can also be published here. A statement regarding possible conflict of interest must be included here (e.g. disclose financial interest in the equipment or method described, research or travelling grant support, consulting services provided, or disclose absence of commercial or propriety interest).

5) References. The author(s) is responsible for accurate references that must conform to journal style. If references are not in journal style, the manuscript will be returned for editing without review. References in the text should quote the last name(s) of the author(s) and the year of publication: (Brown & Smith 2003) or (Brown et al. 2003) when there are three or more authors. The reference list should include only those publications cited in the text and must be listed in alphabetic order with no numbering. Initials of forenames are placed after the surname with no commas, periods or spaces between initials. All articles should be cited in the original language of the reference, not as an English translation. References 'in press' must be filled in at latest in at the proof stage. Reference to unpublished material should state the author's name followed by 'unpublished' or 'personal communications'; such references should not appear in the reference list. Titles of journals are abbreviated according to the recommendations of the Index Medicus.

We recommend the use of a tool such as Reference Manager for reference management and formatting.

Reference Manager reference styles can be searched for here: http://www.refman.com/support/rmstyles.asp

Examples of reference list:

Abrahamsson M, Ohlsson J & Abrahamsson H (2003): Clinical evaluation of an eccentric infrared photorefactor; the PowerRefractor. Acta Ophthalmol Scand 81: 605-610.

Sharaaway T (2003): Glaucoma surgery: Lest we forget. Acta Ophthalmol 81: 553-555.

Bailey IL (1998): Visual acuity. In: Benjamin WJ (ed.) Borish's Clinical Clinical Refraction. Philadelphia: W.B.Saunders 179-202.

6) Figure Legends. Legends to figures should make the meaning of each illustration understandable without reference to the text. Figure legends should be on separate pages.

7) Tables should be numbered consecutively in Arabic numerals and cited in the text. The approximate location in the text should be indicated in the manuscript. Each table should be typed as a separate document. Tables should have legends. Footnotes can be used in tables, if necessary.

8) Illustrations and graphics. All photographs, drawings and graphs are referred to as figures, abbreviated Fig., and should be numbered in sequence with Arabic numerals. Photographs and other images should be cropped so that only relevant parts of original figures are submitted. All figures should be planned to fit the printed column, 56, 117 or 178mm, and non-photographic illustrations should be professionally produced using modern software. Authors are encouraged to print their illustrations in the intended size before submission to make sure that sizes have been chosen correctly. The authors should also adapt graphics for the 3-column format and adjust the font size accordingly. Graphics are not re-drawn by the publisher. Histograms and similiar graphics should not be 3-dimensional. Complicated graphical illustrations can often be made more legible by the use of colour. Figures should be on separate pages. Please submit all line graphics as EPS or PDF files and photographs as TIF or PDF files. When submitting EPS files please embed fonts when you can.

Consult the section on colour charges, colour policy and page charges below.

REVIEW ARTICLES
Review articles should be arranged in the following order: 1) title page; 2) abstract; 3) key words; 4) text, 5) acknowledgement; 6) references; 7) tables; 8) legends to figures; 9) illustrations and graphics.

Review articles have high priority. They are usually invited, but the journal may also accept unsolicited review articles. Articles with clinical relevance are preferred. Manuscripts of this type may be considerably longer than other contributions with numerous illustrations and more extensive reference lists. Review papers have an abstract that may be in a single segment.

CASE SERIES and CASE REPORTS

Case series and case reports should be arranged in the following order: 1) title page; 2) abstract; 3) key words; 4) text, 5) acknowledgement; 6) references; 7) tables; 8) legends to figures; 9) illustrations and graphics.

Acta Ophthalmologica receives many more case reports than it can publish. Published case reports should provide unquestionably new knowledge, or be exceptionally well documented and educational. Authors should check before submission of case reports that their manuscript meets either of these requirements. Most manuscripts in this section are rejected without outside review for lack of new content and low priority. It is usually preferable to submit rare of unusual case observations in a much condensed format as a letter to the editor. Please consult also the Diagnosis/Therapy in Ophthalmology section below.

LETTERS TO THE EDITOR
Acta Ophthalmologica will consider letters for publication. Letters to the editor will be published electronically in each issue of Acta. Other material, including articles, may also be published in electronic issues of Acta and not on paper. The electronic articles and letters will be listed in exactly the same way as other material in Acta, including in international databases. They will be accessible in the same way as other published material, except in the paper issue of the journal.

Letters should encourage scientific discussion on topics pertaining to ophthalmology, and may also consist of short reports or observations. A letter to the editor should start with 'Editor,' and be short and to the point. Long introductions and discussions are unacceptable. Letters should have title page, main text, no abstract, no key words, and no subheadings. Letters should not exceed 600 words and should have a maximum of 5 references and 1 table or 1 illustrations. It could be panel of figures. The editors reserve the right to edit letters for clarity and brevity.

DIAGNOSIS/THERAPY IN OPHTHALMOLOGY
The Diagnosis/Therapy in Ophthalmolgy section features photo essays, i.e. short contributions that focus on images rather than text. Submissions should be based on images which emphasise features relevant to contemporary diagnosis and treatment of eye disease. The aim of this section is to improve patient care by alerting readers to appropriate use of diagnostic techniques and important clinical signs. This section in not intended for reporting rare or unusual findings unless the technique described has wide applicability. The text should have no abstract, no subheadings and should start directly with the case report, followed by a short comment. The text should be about two doubly spaced manuscript pages. The legends are typed on a separate page. Illustrations can include any combination of clinical photographs, ultrasonographic and radiology images, histopathology slides, topographic maps, visual fields and other relevant pictures, provided that they have educational value to the general reader and cropped to show only essential details. The images must be accompanied by a concise comment and up to five references which put them in perspective. Acta will usually only print one article in this section in every issue. Acta has a section editor for this type of article.

THESES
Acta publishes full-text theses (academic dissertations) online. A one or two-page abstract is published in the printed version of the journal, while full text of the theses is available online only. Theses are freely available on the web both to subscribers and to non-subscribers. This means that theses can be found on Medline and are easily available over the world.
