Information For Authors


The Editorial Process

  1. A manuscript will be reviewed for possible publication with the understanding that it is being submitted to Oman Journal of Ophthalmology (OJO) alone at that point in time and has not been published anywhere, simultaneously submitted, or already accepted for publication elsewhere.​
  2. The authors must authorize one amongst them to correspond with the Journal for all matters related to the manuscript and provide all appropriate contact information for this author.
  3. All manuscripts received are duly acknowledged. On submission, editors review all submitted manuscripts initially for suitability for formal review. 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 unlikely to be of interest to OJO readers are also liable to be rejected at this stage itself.
  4. Manuscripts that are found suitable for publication in OJO are sent to two or more expert reviewers. During submission, the contributor is requested to provide names of two or three qualified reviewers who have had experience in the subject of the submitted manuscript, but this is not mandatory. The reviewers should not be affiliated with the same institutes as the contributor/s. However, the selection of these reviewers is at the sole discretion of the editor. The journal follows a masked review process, wherein the authors are unaware of the reviewers' identity and vice versa. 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.
  5. Manuscripts accepted for publication are copy edited for grammar, punctuation, print style, and format.
  6. Page proofs are sent to the corresponding author. The corresponding author is expected to return the corrected proofs within two days. It may not be possible to incorporate corrections received after that period.

The whole process of submission of the manuscript to final decision and sending and receiving proofs is completed online. To achieve faster and greater dissemination of knowledge and information, the journal publishes articles online as 'Ahead of Print' immediately on acceptance.
