Provide a structured abstract of 300 words or less with the following four headings: Objective: State the purpose or objective of the study.
Methods: The following must be included:
• Study Design: Identify the study design using a phrase such as randomized or nonrandomized clinical trial, case-control study, cross-sectional study, cohort study, case series, case report, systemic review, meta-analysis, review, experimental study, or historical manuscript. Additional modifiers can be included (consecutive, retrospective, prospective,observational,interventional, nonconsecutive, etc).
• Setting: Such as multicenter, institutional, clinical practice, etc.
• Participants, Patients or Study Population: Number of patients/eyes, selection procedures, inclusion/criteria, randomization procedure, and masking.
• Intervention or Observation Procedure(s)
• Main Outcome Measure(s)
• Data and Statistical Analyses Results: Briefly summarize the principal outcome measurements/data obtained. Results should be accompanied by data with confidence intervals and the exact level of statistical significance. Conclusions: Provide brief and concise conclusions(s) directly supported by the data.
Number the pages of the manuscript consecutively, beginning with the title page as page one. The text should, in general, not exceed 18 double-spaced typewritten pages.
Organize and prepare the manuscript to include the following sections:
Introduction: The Introduction, without a heading, should refer only to the most pertinent past publications and should not be an extensive review of the literature. Include a brief background, the research question and/or rationale, objectives/purposes of the study, and major hypothesis to be tested, if any.
Methods: Methods should be written with sufficient detail to permit others to duplicate the work. The following should be included:
• Study Design: Identify the study design using a phrase such as randomized or nonrandomized clinical trial, case-control study, cross-sectional study, cohort study, case series, case report, systematic review, metaanalysis, review, experimental study, or historical manuscript. Additional modifiers may be included (e.g. consecutive, nonconsecutive, retrospective, prospective, observational, interventional).
• Setting: (e.g. multicenter, institutional, clinical practice)
• Participants, Patients or Study Population: Number of patients/eyes, selection procedures, inclusion/exclusion criteria, randomization procedure, and masking.
• Intervention or observation procedure(s)
• Main and secondary outcome measure(s)
• Data and statistical analyses.
For clinical studies, statements regarding adherence to the Declaration of Helsinki, approval by Institutional Review Board (IRB)/Ethics Committee, and description of the informed consent process should be included. For animal research, the Association for Research in Vision and Ophthalmology (ARVO) guidelines for animal research should be followed and adherence to the said guidelines should be stated. Previously published procedures should be identified by reference only.
Results: Results must be concise. Provide demographic data of the study population. Describe outcomes and measurements in an objective sequence with minimum discussion. Data should be accompanied by confidence intervals (usually at the 95% interval) and exact p values or other indications of statistical significance.
Discussion: The Discussion should be restricted to the significant findings presented. Avoid excessive generalization and undue speculation. Digressions and theorizing are not appropriate. Elucidate on (but do not reiterate the results, provide responses to other and contradictory literature, identify limitations or qualifications of the study and state the conclusions that are directly supported by the data. Give equal emphasis to positive and negative findings, whether and what additional study is required, and conclude with the clinical applications or implications supported by the study. The conclusion(s) is (are) incorporated into the end of the discussion and should be directly supported by the results. Authors should avoid making statements on exonomic benefits and costs unless their manuscript includes economic data and analyses. Avoid claiming priority of the content unless you provide the literature search protocol used.
A brief report is an original contribution (generally an interesting case, a case series, surgical technique, or experimental study) with a concise message. Manuscript must adhere to the PJO format guidelines, except that the abstract should contain no more than 150 words and the body no more than 1,000 words. References should be limited to 5.
Acknowledge statistical consultation and assistance (when provided by someone other than an author) in an acknowledgement at the end of the article, before the references. Include the name, degreed, and affiliation of the individual. Consultants (other than statistical consultants), editorial assistants, photographers, artists, laboratory associates, and others who assist in preparation of a manuscript are not to be acknowledged, however valuable their service.
Because readers may infer their endorsement of the data and conclusions, all persons acknowledged must have given permission to be acknowledged and this must be confirmed in the cover letter.
An appendix should be used very sparingly. However, it is appropriate to provide survey forms, to list the members of a study group, or explain complex formulas or information.
In studies involving a study group, the writing group authors should be listed along with the group name (e.g. Smith TT, Jones JJ on behalf of the Pediatric Amblyopia Study Group) on the title page. Other group members should be listed in an appendix. When the study group name alone is listed on the title page, the Copyright Transfer Agreement requires only the original signature of the Corresponding Author. When a series of authors is listed on the title page in conjunction with the study group name, the Copyright Transfer Agreement must include the original signatures of these authors.
List only references that are pertinent to the manuscript. Cite only published studies as references. Cite/Quote from the entire study, not the abstract. You may acknowledge “unpublished data” or submitted articles within parentheses in the text. Reference to a “personal communication” within parentheses in the text must be accompanied by a signed permission letter from the individual being cited.
References should be numbered consecutively in the text and in the reference list. In the text, reference numbers are entered as superscripts. The references must be verified by the author(s) against the original documents. PubMed (http://www.ncbi.nlm.nih.gov) offers a useful reference checker. References to journal articles should include: the author or authors (for more than four authors, list only the first three followed by “et al.”), title, journal name (as abbreviated in Index Medicus), year, volume number, and inclusive page numbers.
References to books should include: the author or authors, chapter title (if any), editor or editors (if any), book title, edition (other than the first), city of publication, publisher, copyright year, and inclusive pages of the chapter or section cited.
Web site references must include author (or web site owner), title of article, date article was posted, publication (if applicable), complete web site address, and date accessed.

Tables should follow references. Each table must be titled and numbered consecutively using Arabic numbers as mentioned in text. The title should be brief and fully understandable without reference to the text. Each table column and row must have a heading. Tables that indicate the mean should have the corresponding standard deviation. Legends must identify all symbols that appear on the tables and graphs.
FIGURES (PHOTOGRAPHS, ILLUSTRATIONS, AND GRAPHS)
Submit three (3) identical complete sets of prints and a digital copy if available. Each print must be separately labeled with the author’s name, figure number and an indication (arrow) as to orientation (up). Put all information on a separate label on the back of the illustration to avoid writing on or damage to the prints.
Prints of figures (clinical photographs, fluorescein angiograms, CT, MRI, X-ray, photomicrographs, TEM, SEM, graphs, etc.) must be large enough to be easily read, preferably 4 x 6 inches. The digital copy of each photograph or illustration should be saved in individual files in either TIF or JPEG format with a resolution of at least 300 dpi. Photographs and illustrations saved in “Power point” or “Word” format are not acceptable. Graphs may be submitted in “Power Point” or “Excel” format. Text in figures must not be smaller than 10 points when finally reproduced in the Journal.
Each figure must be numbered consecutively in Arabic numerals by order of citation in the text. Each should have a brief explanatory legend. Legends must identify all symbols or letters that appear on the prints. Histologic figures, stains, and magnifications should be noted in the legend. Graphs that indicate the mean should include the standard deviation. Any figure that has been published elsewhere should have an acknowledgment to the original source. A copy of the release to publish the figure signed by the copyright holder must also be submitted.
Clinical photographs should be masked when possible to prevent identification of the patient. Clinical photographs that permit identification of an individual must be accompanied by a signed statement by the patient or guardian granting permission for publication of the pictures for educational purposes.
Color reproduction of figures will be published at the author’s expense based on prevailing rates. Check with the PAO office for exact cost. If a manuscript has been reviewed and accepted with color photos, it must be published with color photos. The author may opt to have them printed in black and white at no expense.
Restrict abbreviations to those that are widely used and understood. Avoid abbreviations that have meaning only in the context of your specific manuscript. If an abbreviation is to be used, it should appear in parentheses immediately after the term or phrase to which it refers when it is stated for the first time in the text.
INSTRUMENTS, DRUGS, AND MANUFACTURER NAMES
Use generic names only in the text body. State the trade name of a particular drug cited in parentheses includingmanufacturer’s name, city, state and/or country when first mentioned in the text. With regard to instruments utilized in the study, enclose in parentheses the specific model, manufacturer’s name, city, state and/or country.
Each submission must be accompanied with a letter to the editor in chief. It must identify the corresponding author, list any meetings where the material is under consideration for presentation or has been previously presented and disclose any conflict of interest. The transmittal letter must include a copyright transfer. The editorial office must be supplied with phone and fax numbers for the corresponding and first author(s), and e-mail addresses, if available.
Consideration of manuscripts for publication in the Philippine Journal of Ophthalmology is dependent on the assurance that the material (in whole or part) is not under consideration by another journal, is not in press in any other format, and has not been previously published. Each author must sign a statement transferring copyright ownership to the Philippine Academy of Ophthalmology. Manuscripts which have been accepted for publication may be published in another journal after securing a written consent from the editor in chief of the Philippine Journal of Ophthalmology.
