Journal of the Nigerian Optometric Association (JNOA) is the official scientific publication of the Nigerian Optometric Association. It is a peer-reviewed, open-access journal devoted to bringing together up-to-date clinical and scientific research information and novel developments in the broad fields of optometry and vision science including basic and clinical research aimed at advancing the science, technology, ethics and practice of Optometry and Health sciences.
Scope of the Journal
The scope of the journal covers basic, translational and clinical research in optometry and vision science. The journal publishes research in the broad fields of Optometry, Ophthalmic optics, ocular surface, Basic and Applied Vision Science and Public Health; Primary Care Optometry, Public Health Optometry, Rehabilitative Optometry and Low Vision Care, Paediatric Optometry, Corneal and Contact Lenses, Ocular Health, Orthoptics, Anatomy, Physiology, Epidemiology, Economics and Sociology of Vision and Blindness, Ocular Biomedics, Optics and Instrumentation, Optometric Education and History, etc. The audience of JNOA includes Optometrists, Ophthalmologists, and Vision Scientists as well as undergraduate and post-graduate students in these field.
The journal is committed to meeting and upholding standards of ethical behavior at all stages of the publication process. We follow closely the industry associations, such as the Committee on Publication Ethics (COPE), International Committee of Medical Journal Editors (ICMJE) and World Association of Medical Editors (WAME), that set standards and provide guidelines for best practices in order to meet these requirements.
Instructions to Authors
The journal will consider the following categories of manuscripts for publication:
a) Original research reports describing new experimental findings, or analyses (e.g. post hoc, subgroup, meta-analysis where an overall statistic is derived).
b) Review articles. The following types of reviews:
- General reviews that provide a synthesis of an area that fits within the aims and scope of the journal;

The Publishing Process
A manuscript will be reviewed for possible publication with the understanding that it is being submitted to Journal of the Nigerian Optometric Association alone at that point in time and has not been published anywhere, simultaneously submitted, or already accepted for publication elsewhere. The journal expects that authors would designate one of them as to corresponding author to correspond with the Journal for all matters related to the manuscript. All manuscripts received are duly acknowledged. On submission, editors review all submitted manuscripts initially for suitability for formal review as well as run a plagiarism test. Manuscripts with insufficient originality, serious scientific or technical flaws, or lack of a significant message are rejected before proceeding for formal peer-review.
Manuscripts that are found suitable for publication in JNOA are sent to two or more expert reviewers. The journal follows a double-blind review process, wherein the reviewers and authors are unaware of each other’s identity. Every manuscript is also assigned to a member of the editorial team, who based on the comments from the reviewers takes a final decision on the manuscript. The comments and suggestions (acceptance/ rejection/ amendments in manuscript) received from reviewers are conveyed to the corresponding author. If required, the author is requested to provide a point by point response to reviewers’ comments and submit a revised version of the manuscript. This process is repeated till reviewers and editors are satisfied with the manuscript. Page proofs are sent to the corresponding author after final acceptance. The corresponding author is expected to return the corrected proofs within three days. It may not be possible to incorporate corrections received after that period.
Preparation of manuscript
- Manuscript – the manuscript must be original to the author(s) and should be sent to the editor-in-chief at: firstname.lastname@example.org. Each manuscript should not exceed 16 pages/8000 words except for review articles.
- Format of the paper
The paper should include
A cover letter accompanying the manuscript, indicating the significance of the study and also certifying that the article has not been previously published elsewhere. All Authors full names, email address and affiliations, including corresponding author’s telephone number will be required. The Journal will publish manuscripts written in English, using A4 paper size with 1.25 inches margin on all sides. Preferred font size is 12 using Times New Romans. For scientific notations, measurements and visual acuity, authors should use the metric system notation and standard abbreviations.
Five Types of Manuscripts may be Submitted.
These include randomized controlled trials, intervention studies, studies of screening and diagnostic test, outcome studies, cost effectiveness analyses, case-control series, and surveys with high response rate. The text of original articles should be divided into sections with the headings Abstract, Keywords, Introduction, Methods, Results, Discussion, Conclusion, References, Tables and Figure legends.
Abstract: It should be structured and divided into sections with the headings “Purpose, Methods, Results, Conclusion” and it should be provided in maximum 250 words.
Keywords: Three to six keywords should be included.
It is expected that these articles would be written by individuals who have done substantial work on the subject or are considered experts in the field. A short summary of the work done by the contributor(s) in the field of review should accompany the manuscript.
The word count is variable, depending on content and type of submission. The manuscript should have an unstructured abstract (maximum 250 words) representing an accurate summary of the article. The section titles would depend upon the topic reviewed. Authors submitting review article should include a section describing the methods used for locating, selecting, extracting, and synthesizing data. These methods should also be summarized in the abstract.
The journal expects the contributors to give post-publication updates on the subject of review. The update should be brief, covering the advances in the field after the publication of the article and should be sent as a letter to editor, as and when major development occurs in the field.
Case Reports/case series:
New, interesting and rare cases can be reported. They should be unique, describing a great diagnostic or therapeutic challenge and providing a learning point for the readers. Cases with clinical significance or implications will be given priority. These communications could be of up to 1200 words (excluding abstract and references) and should have the following headings: Abstract, Keywords, Introduction, Case Report, Discussion, Clinical significance/implications, References (up to 15 references), Tables and Legends in that order.
Abstract should be structured and divided into sections with the headings “Purpose, Case Report, and Conclusion” and it should be provided in maximum 150 words.
Short communication/Letter to Editor:
These should be short and decisive observations. They should preferably be related to articles previously published in the Journal or views expressed in the journal. They should not be preliminary observations that need a later paper for validation. The letter could have up to 500 words and 5 references. It could be generally authored by not more than four authors.
These should cover a single topic of contemporary issue and authors should be written invited only.
In all cases, authors should ensure compliance with the highest standards of research ethics. A statement indicating such compliance should be included in the methodology section of each submission. It is the authors responsibility to ensure that ethical approval is obtained from relevant Institutional Review Boards and the Journal could request a copy of such IRB approval.
