The collagenase type Ⅱ solution was applied to both the left and right eyes of the rabbit after epithelial debridement. Two weeks after collagenase treatment, the corneal morphology parameters (by Pentacam) and biomechanical parameters (by Corvis ST) in vivo were assessed to determine whether corneal ectasia had occurred. Subsequently, these eyes were randomly divided into three groups. The first group did not receive any treatment. The second and third groups underwent A-CXL surgery (30 mW/cm<sup>2</sup>, 4 min) in normoxic environment (21 % oxygen) or hyperoxic environment (>90 % oxygen), respectively. Four weeks later, changes in the corneal morphology parameters and biomechanical parameters in vivo were evaluated. Moreover, the elastic modulus (by biaxial stretch test) and histology of corneal tissues were also assessed ex vivo. Morphological and biomechanical parameters in vivo suggest the occurrence of corneal ectasia after collagenase treatment. No significant differences were found in morphological parameters changes obtained by Pentacam among three groups at 4 weeks after A-CXL surgery. However, the results of SD-OCT revealed that the corneal thickness change at the peripheral position along the nasal-temporal direction in the hyperoxic A-CXL group was lower compared with the other two groups. Biomechanical tests showed that, compared with the ectatic cornea group, the ability of the cornea to resist deformation increased only in the hyperoxic A-CXL group, with lower A1V and IR in vivo and higher elastic modulus ex vivo, while the normoxic A-CXL exhibited similar postoperative outcomes to untreated ectatic cornea. The histological results showed that no obvious signs of apoptosis were observed in all groups.

Staphylococcus aureus is frequently isolated from bacterial keratitis cases. This organism's virulome and propensity for antibiotic resistance make it a formidable ocular pathogen that is often difficult to eradicate. S. aureus is not typically isolated from an immunocompetent ocular environment. We therefore hypothesized that elements of innate immunity are important in protecting the cornea from S. aureus infection, so their absence would facilitate persistence that might lead to keratitis. In the current study, we used a corneal scratch and topical inoculation model with S. aureus strain 8325-4 to infect mouse eyes and assess infection and inflammation in wild type C57BL/6J mice and mice genetically deficient in TLR2 (i.e. TLR2-/- or TLR2/4-/-) or TLR2-associated proinflammatory mediators (CXCL1-/-, CXCL2-/-, CXCL10-/-, CCL2-/-, CCL3-/-, or TNFα-/-). We included males and females in these experiments to determine whether sex was a biological variable. We assessed staphylococcal burden and clearance by quantifying colony forming units (CFU)/eye, inflammation by quantifying myeloperoxidase (MPO) from infiltrating neutrophils, and ocular pathology each day for 3-6 days, depending on the assay. Our data shows that, in general, the absence of the TLR2 pathway and its downstream mediators facilitated persistence of S. aureus in the mouse eye, but did not lead to ulcerative keratitis. S. aureus was cleared from the C57BL/6J mouse cornea within 3 days, while the organism persisted in knockout mouse eyes through day 6. Although pockets of staphylococci and neutrophil influx at the sites of infection were observed in some eyes, there were surprisingly very few corneal epithelial defects noted irrespective of mouse strain. These results suggest that defects in innate immunity create an environment that can facilitate persistence of S. aureus at the ocular surface, an area typically devoid of harmful bacteria.</p>","PeriodicalId":12177,"journal":{"name":"Experimental eye research","volume":" ","pages":"110682"},"PeriodicalIF":2.7,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145274374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
