The donation-transplantation process and corneal graft failure: A case-control study. PLoS One 2025; 20:e0321225. [PMID: 40402957 PMCID: PMC12097642 DOI: 10.1371/journal.pone.0321225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2024] [Accepted: 03/03/2025] [Indexed: 05/24/2025] Open
Abstract
INTRODUCTION The survival after a corneal transplantation depends on several factors, many of which are not fully known. OBJECTIVE The present study aimed to verify the relationship between the factors inherent to the donation-transplantation process in graft failure. MATERIALS AND METHODS Longitudinal case-control study carried out in a reference service in corneal transplantation in northeastern Brazil, which included transplanted patients with corneal graft failure and their respective controls. The sample consisted of 27 cases of graft failure and 54 controls. RESULTS A total of 427 transplantations were performed between 2010 and 2016 in the studied service, during which 27 cases of corneal graft failure were identified, representing a failure rate of 9.04%. The intergroup descriptive analysis identified the predominance of corneal graft failure in females (cases: 59.26%; control: 55.56%), brown (cases: 65.38%; controls: 53.70%), single (cases: 71.43%; controls: 68.52%) and residents in the capital and metropolitan region (cases: 66.67%; controls: 50%). The mean age of the patients who underwent corneal transplantation was 52.31 years (cases: 56.15 years; control: 50.39 years). Regarding the "type of keratoplasty", the prevalence of penetrating keratoplasty was observed in 87.65% of the transplantations (cases: 81.48%; controls: 18.52%). In addition, 85.19% of the failures were late and 46.91% of the patients subjected to transplantation had already undergone an ophthalmological surgical procedure previously. CONCLUSION The present study identified the following variables as factors of the donation-transplantation process associated with corneal graft failure: donor button size ≤ 8.25 mm, donor-recipient button size difference less than 0.25 mm, death due to respiratory failure, time interval between enucleation-preservation and corneal endothelial disorder.

Abstract
Oxidative stress is an important pathomechanism found in numerous ocular degenerative diseases. To provide a better understanding of the mechanism and treatment of oxidant/antioxidant imbalance-induced ocular diseases, this article summarizes and provides updates on the relevant research. We review the oxidative damage (e.g., lipid peroxidation, DNA lesions, autophagy, and apoptosis) that occurs in different areas of the eye (e.g., cornea, anterior chamber, lens, retina, and optic nerve). We then introduce the antioxidant mechanisms present in the eye, as well as the ocular diseases that occur as a result of antioxidant imbalances (e.g., keratoconus, cataracts, age-related macular degeneration, and glaucoma), the relevant antioxidant biomarkers, and the potential of predictive diagnostics. Finally, we discuss natural antioxidant therapies for oxidative stress-related ocular diseases.

Ascorbic acid ameliorates corneal endothelial dysfunction and enhances cell proliferation via the noncanonical GLUT1-ERK axis. Biomed Pharmacother 2021; 144:112306. [PMID: 34656060 DOI: 10.1016/j.biopha.2021.112306] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 10/01/2021] [Accepted: 10/05/2021] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND The pumping function of corneal endothelial cells (CECs) plays a pivotal role in the maintenance of corneal water homeostasis. Corneal endothelial dysfunction (CED) leads to corneal edema and opacity, but with the exception of keratoplasty, no optimal therapeutic strategies have been established for CED. In this study, we aimed to investigate the ameliorative effect of ascorbic acid (AA) on CED and the underlying mechanism of action in the corneal endothelium. METHODS Rabbit corneal endothelial damage was induced by anterior chamber injection of benzalkonium chloride (BAK). AA was topically administered to the corneal surface, and the transparency and thickness of the cornea were assessed by external eye photography, slit-lamp photography, and ultrasonic pachymetry. To further analyze the mechanism, rabbit CECs and immortalized human CECs (B4G12 cells) were cultured. A ferric reducing/antioxidant and AA (FRASC) assay was performed to measure the AA concentration. Cell proliferation was evaluated by cell counting and bromodeoxyuridine (BrdU) labeling assays, and protein expression was examined by liquid chromatography-mass spectrometry (LC/MS) and immunoblotting. The involvement of glucose transporter 1 (GLUT1) and phospho-ERK was evaluated via GLUT1-siRNA and phospho-ERK inhibitor (PD98059) treatment. INTERPRETATION We observed that topical AA ameliorates BAK-induced rabbit corneal endothelial damage. Furthermore, we demonstrated that AA is transported into B4G12 cells via GLUT1, and afterward, AA increases ERK phosphorylation and promotes cell proliferation. Our findings indicate that CEC proliferation stimulated via the noncanonical AA-GLUT1-ERK axis contributes to AA-enhanced healing of CED.
