Abstract

Introduction: Chemical eye injury is an ophthalmic emergency which can lead to loss of vision. We aimed to determine the prognostic value of tear film pH on presentation in acute chemical eye injuries.

Methods: Demographics, pH values, causative chemical, injury circumstances, injury severity, and clinical and visual outcomes were assessed from previously collated data from patients presenting to the emergency eye department (EED) in a UK tertiary hospital. All patients who had pH measured before irrigation in the EED were included. Associations with injury severity and clinical and visual outcomes were analysed.

Results: Pre-irrigation pH was recorded in 135 eyes (113 patients, 66.4% male, mean age 35.5 years [range 2-78; standard deviation (SD) 15.4]; 15 acid, 108 alkali, 12 unknown). The pH within 24 h of injury (n = 108 eyes) correlated significantly with injury severity (r_s = 0.20, p = 0.02). In patients with abnormal pH on presentation (n = 26 eyes), pH correlated strongly with injury severity (r_s = 0.72, p < 0.01). There was no significant correlation with visual outcome at follow-up (n = 70 eyes, 60 patients, follow-up 1-3929 days, mean 579.4 days, SD 1206.0 days; r_s = 0.12, p = 0.11). Presenting pH below 6.5 or above 7.5 was a significant predictive factor for the presence of limbal stem cell deficiency (LSCD) (univariate binary logistic regression analysis, p = 0.026, Nagelkerke R-squared = 0.090).

Conclusion: Deranged pH correlated with burn severity in patients presenting within 24 h of injury and was a significant predictive factor for LSCD.

急性眼表化学损伤的预后- pH测量在表现中的作用：一项回顾性队列研究。

导读：化学性眼损伤是一种可导致视力丧失的眼科急症。我们的目的是确定泪膜pH值对急性化学性眼损伤的预后价值。方法：统计数据、pH值、致病化学物质、损伤情况、损伤严重程度、临床和视力结果，从英国一家三级医院急诊科（EED）就诊的患者先前整理的数据进行评估。所有在EED冲洗前测量pH值的患者都包括在内。分析了与损伤严重程度、临床和视觉结果的关系。结果：135只眼(113例，男性66.4%，平均年龄35.5岁，范围2 ~ 78岁；标准差（SD） 15.4]；15种酸，108种碱，12种未知)。损伤24 h内pH值（n = 108眼）与损伤严重程度显著相关（rs = 0.20, p = 0.02）。在出现pH值异常的患者中（n = 26只眼），pH值与损伤严重程度密切相关（rs = 0.72, p = 0.12, p = 0.11）。pH值低于6.5或高于7.5是角膜缘干细胞缺乏症（LSCD）存在的重要预测因素（单变量二元logistic回归分析，p = 0.026, Nagelkerke r²= 0.090）。结论：损伤后24小时内出现的患者，pH紊乱与烧伤严重程度相关，是LSCD的重要预测因素。

期刊介绍： Aims and Scope Ophthalmology and Therapy is an international, open access, peer-reviewed (single-blind), and rapid publication journal. The scope of the journal is broad and will consider all scientifically sound research from preclinical, clinical (all phases), observational, real-world, and health outcomes research around the use of ophthalmological therapies, devices, and surgical techniques. The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/series, trial protocols and short communications such as commentaries and editorials. Ophthalmology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. Rapid Publication The journal’s publication timelines aim for a rapid peer review of 2 weeks. If an article is accepted it will be published 3–4 weeks from acceptance. The rapid timelines are achieved through the combination of a dedicated in-house editorial team, who manage article workflow, and an extensive Editorial and Advisory Board who assist with peer review. This allows the journal to support the rapid dissemination of research, whilst still providing robust peer review. Combined with the journal’s open access model this allows for the rapid, efficient communication of the latest research and reviews, fostering the advancement of ophthalmic therapies. Open Access All articles published by Ophthalmology and Therapy are open access. Personal Service The journal’s dedicated in-house editorial team offer a personal “concierge service” meaning authors will always have an editorial contact able to update them on the status of their manuscript. The editorial team check all manuscripts to ensure that articles conform to the most recent COPE, GPP and ICMJE publishing guidelines. This supports the publication of ethically sound and transparent research. Digital Features and Plain Language Summaries Ophthalmology and Therapy offers a range of additional features designed to increase the visibility, readership and educational value of the journal’s content. Each article is accompanied by key summary points, giving a time-efficient overview of the content to a wide readership. Articles may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand the scientific content and overall implications of the article. The journal also provides the option to include various types of digital features including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations. All additional features are peer reviewed to the same high standard as the article itself. If you consider that your paper would benefit from the inclusion of a digital feature, please let us know. Our editorial team are able to create high-quality slide decks and infographics in-house, and video abstracts through our partner Research Square, and would be happy to assist in any way we can. For further information about digital features, please contact the journal editor (see ‘Contact the Journal’ for email address), and see the ‘Guidelines for digital features and plain language summaries’ document under ‘Submission guidelines’. For examples of digital features please visit our showcase page https://springerhealthcare.com/expertise/publishing-digital-features/ Publication Fees Upon acceptance of an article, authors will be required to pay the mandatory Rapid Service Fee of €5250/$6000/£4300. The journal will consider fee discounts and waivers for developing countries and this is decided on a case by case basis. Peer Review Process Upon submission, manuscripts are assessed by the editorial team to ensure they fit within the aims and scope of the journal and are also checked for plagiarism. All suitable submissions are then subject to a comprehensive single-blind peer review. Reviewers are selected based on their relevant expertise and publication history in the subject area. The journal has an extensive pool of editorial and advisory board members who have been selected to assist with peer review based on the afore-mentioned criteria. At least two extensive reviews are required to make the editorial decision, with the exception of some article types such as Commentaries, Editorials, and Letters which are generally reviewed by one member of the Editorial Board. Where reviewer recommendations are conflicted, the editorial board will be contacted for further advice and a presiding decision. Manuscripts are then either accepted, rejected or authors are required to make major or minor revisions (both reviewer comments and editorial comments may need to be addressed). Once a revised manuscript is re-submitted, it is assessed along with the responses to reviewer comments and if it has been adequately revised it will be accepted for publication. Accepted manuscripts are then copyedited and typeset by the production team before online publication. Appeals against decisions following peer review are considered on a case-by-case basis and should be sent to the journal editor. Preprints We encourage posting of preprints of primary research manuscripts on preprint servers, authors’ or institutional websites, and open communications between researchers whether on community preprint servers or preprint commenting platforms. Posting of preprints is not considered prior publication and will not jeopardize consideration in our journals. Authors should disclose details of preprint posting during the submission process or at any other point during consideration in one of our journals. Once the manuscript is published, it is the author’s responsibility to ensure that the preprint record is updated with a publication reference, including the DOI and a URL link to the published version of the article on the journal website.
