Submission rules
All manuscripts must be submitted electronically via the website of the journal ( The system will guide the authors stepwise to complete the submission process. Before starting, authors must make sure that:
- they have prepared an original work following the instructions provided in the Authors guidelines (
- their work has neither been published already, submitted nor considered for publication elsewhere.
- they have completed and signed the copyright release form

Please notice that it will not be possible for authors to change authors names or their order after acceptance of the manuscript.

Evaluation procedure:

Admissibility check: Scope, language and similarity check
During the first check, editors may return the articles for the following reasons:
- The manuscript does not follow instructions given in the Authors Guidelines (,
- Author names and their order in the manuscript are not consistent with those on the copyright form,
- The similarity score generated by the similarity report (iThenticate result) exceeds 25%.

Review process
The reviewing is blind peer review process, where the reviewers have access to the authors’ name and affiliations. The identity of referees is however not revealed to authors.
Authors have to cooperate fully with this process. They should provide quickly any information requested by the editorial staff that may concern the provided data, proof of ethics approval, patient consents or copyright permissions. Also, for manuscripts for which revisions are required, authors should provide in a timely response that considers point-by-point reviewers’ comments. Their manuscript should be updated in accordance with this response and should be re-submitted via the submission system before the given deadline.

Before publication, proofs will be sent to authors for correction. No further changes will be accepted after the proof approval.

Plagiarism is not tolerated by the YMJ. All submitted manuscripts will be checked for similarity through the iThenticate® software, that matches the content of the manuscript with billions of published documents to generate a similarity report. The manuscripts submitted to the YMJ with similarity scores that exceed 25% will not be processed.

Ethical Policies
Any complication that may arise from the application of ethical rules will be the responsibility of the authors.
Particularly, concerning clinical studies, no information that may lead to patient identification (such as names, abbreviations, patient numbers, etc..) should be provided.

Patients must be blinded if there is no patient consent and/or any results related an ophthalmologic study.
Studies involving human subjects must be carried out according to the World Medical Association’s (WMA) Declaration of Helsinki. Authors must clearly state that the study protocol received institutional ethics board approval and that all participants provided informed consent in the format required by the relevant authorities and/or boards. The relevant ethics board(s) and approval code(s) must be given in the Methods part of the research article.

Studies involving animals must be carried out according to the principles stated in the Guide for the Care and Use of Laboratory Animals Authors must clearly state that the study protocol received institutional ethics board approval. The relevant ethics board(s) and approval code(s) must be given in the Methods part of the research article.

After online publication, further changes can only be made in the form of an Erratum, which will be hyperlinked to the article.

Conflict of interest
Authors must indicate whether or not they have a financial relationship with the organization that sponsored the research. This note should be added in a separate section before the reference list.
If no conflict exists, authors should state: “The authors declare that they have no conflict of interest.”

Suggesting / excluding reviewers
Authors are welcome to suggest suitable reviewers and/or request the exclusion of certain individuals when they submit their manuscripts. When suggesting reviewers, authors should make sure they are totally independent and not connected to the work in any way. It is strongly recommended to suggest a mix of reviewers from different countries and different institutions. Please note that the YMJ may not use the suggestions, but suggestions are appreciated and may help facilitate the peer review process.

Authorship principles
These guidelines describe authorship principles and good authorship practices to which prospective authors should adhere to.

Data transparency
All authors are requested to make sure that all data and materials as well as software application or custom code support their published claims and comply with field standards.

Role of the Corresponding Author

One author is assigned as Corresponding Author and acts on behalf of all co-authors and ensures that questions related to the accuracy or integrity of any part of the work are appropriately addressed.
The Corresponding Author is responsible for the following requirements:

  • ensuring that all listed authors have approved the manuscript before submission, including the names and order of authors;
  • managing all communication between the Journal and all co-authors, before and after publication;*
  • providing transparency on re-use of material and mention any unpublished material (for example manuscripts in press) included in the manuscript in a cover letter to the Editor;
  • making sure disclosures, declarations and transparency on data statements from all authors are included in the manuscript as appropriate.

The primary affiliation for each author should be the institution where the majority of their work was carried out. If an author has subsequently moved, the current address may additionally be stated. Addresses will not be updated or changed after publication of the article.

Cell lines
If cells are used, authors must declare in the manuscript: what cell lines were used by describing the source of the cell line, including when and from where it was obtained. If cells were bought from a life science company the following need to be given in the manuscript: name of company (that provided the cells), cell type, catalog number of cell line.

Clinical Trial Registration
The World Health Organization (WHO) definition of a clinical trial is "any research study that prospectively assigns human participants or groups of humans to one or more health-related interventions to evaluate the effects on health outcomes". The WHO defines health interventions as “A health intervention is an act performed for, with or on behalf of a person or population whose purpose is to assess, improve, maintain, promote or modify health, functioning or health conditions” and a health-related outcome is generally defined as a change in the health of a person or population as a result of an intervention.
To ensure the integrity of the reporting of patient-centered trials, authors must register prospective clinical trials (phase II to IV trials) in suitable publicly available repositories. For example or any of the primary registries that participate in the WHO International Clinical Trials Registry Platform.
The trial registration number (TRN) and date of registration should be included as the last line of the manuscript abstract. For clinical trials that have not been registered prospectively, authors are encouraged to register retrospectively to ensure the complete publication of all results. TRN, date of registration and the words ‘retrospectively registered’ should be included as the last line of the manuscript abstract.

Standards of reporting
Checklists are available for a number of study designs, including:
Randomised trials (CONSORT) and Study protocols (SPIRIT)
Observational studies (STROBE)
Systematic reviews and meta-analyses (PRISMA) and protocols (Prisma-P)
Diagnostic/prognostic studies (STARD) and (TRIPOD)
Case reports (CARE)
Clinical practice guidelines (AGREE) and (RIGHT)
Qualitative research (SRQR) and (COREQ)
Animal pre-clinical studies (ARRIVE)
Quality improvement studies (SQUIRE)
Economic evaluations (CHEERS)

Informed consent
All individuals have individual rights that are not to be infringed. Individual participants in studies have, for example, the right to decide what happens to the (identifiable) personal data gathered, to what they have said during a study or an interview, as well as to any photograph that was taken. In many instances authors will need to secure written consent before including images. Complete anonymity is difficult to achieve in some cases. Detailed descriptions of individual participants, whether of their whole bodies or of body sections, may lead to disclosure of their identity. Informed consent for publication should be obtained if there is any doubt.

Summary of requirements
Please see the various examples of wording below and revise/customize the sample statements according to your own needs.

Informed consent was obtained from all individual participants included in the study.

Informed consent was obtained from legal guardians.

Written informed consent was obtained from the parents.

Verbal informed consent was obtained prior to the interview.

Sample statements for “Consent to publish”:

The authors affirm that human research participants provided informed consent for publication of the images in Figure(s) 1a, 1b and 1c.

The participant has consented to the submission of the case report to the journal.

Patients signed informed consent regarding publishing their data and photographs.

Sample statements if identifying information about participants is available in the article:

Additional informed consent was obtained from all individual participants for whom identifying information is included in this article.

Authors are responsible for correctness of the statements provided in the manuscript. See also Authorship Principles. The Editor-in-Chief reserves the right to reject submissions that do not meet the guidelines described in this section.

Images will be removed from publication if authors have not obtained informed consent or the paper may be removed and replaced with a notice explaining the reason for removal.
