Objective:To investigate the risk factors of secondary glaucoma after keratoplasty and construct a prediction model.Methods:The clinical data of 366 patients who had corneal transplantation at our facility between January 2020 and January 2023 were examined retrospectively.Based on the occurrence of secondary glaucoma after surgery,the patients were divided into two groups:secondary glaucoma group(n=57)and non-secondary glaucoma group(n=309).The clinical risk factors of the two groups were compared to identify the risk factors for secondary glaucoma following corneal transplantation.The prediction model was constructed according to the results,and the receiver operating characteristic(ROC)curve was plotted to assess the predictive accuracy of the model for the development of secondary glaucoma following corneal transplantation.Results:A total of 366 patients after keratoplasty were included in this study.The incidence of secondary glaucoma was 15.57%(57/366).Stepwise Logistic regression analysis showed that infectious cornea(OR=2.419,95%CI 1.132-5.982),preoperative hypopyema(OR=4.353,95%CI 1.655-7.931),preoperative ulcer area>1/2 cornea(OR=3.972,95%CI 1.524-7.082),preoperative glaucoma history(OR=4.230,95%CI 1.628-6.263),previous ophthalmic surgery history(OR=2.948,95%CI 1.135-7.836),aphakic or pseudophakia(OR=2.398,95%CI 1.135-7.421),penetrating keratoplasty(OR=2.872,95%CI 1.098-6.827),combined surgery(OR=1.862,95%CI 1.120-7.862),long-term use of hormones(OR=3.981,95%CI 1.209-8.876)and smoking(OR=3.981,95%CI 1.209-8.876)were risk factors for secondary glaucoma after keratoplasty.The area under the ROC curve of the model was 0.804(95%CI 0.745-0.914),and the sensitivity and specificity were 0.83 and 0.78,respectively.Conclusion:The risk prediction model based on the risk factors of secondary glaucoma after corneal transplantation has great reference value for nursing after corneal transplantation,and is convenient,easy to conduct and suitable for clinical application.
