Analysis of influencing factors of refusal of vitrectomy in patients with proliferative diabetic retinopathy
Objective To analyze the influencing factors of refusal of vitrectomy in patients with proliferative diabetic retinopathy(PDR).Methods A total of 517 patients with PDR who underwent vitrectomy in Xingtai City from January 2021 to August 2022 were selected and divided into two groups according to whether they underwent surgical treatment.The personal and disease charac-teristics of the patients were collected.Logistic regression was used to analyze the influencing factors of non-vitrectomy.Results 126 patients(24％)did not undergo vitrectomy.There were statistically significant differences in the proportion of patients received retinal photocoagulation,combined with other serious systemic diseases,and preoperative visual acuity improvement between the two groups(P＜0.05).Multivariate analysis showed that no previous retinal photocoagulation treatment(OR=0.414,95％CI 0.236～0.724,P=0.002),combined with other serious systemic diseases(OR=11.812,95％CI 6.446～21.646,P＜0.001),and preoperative visual acuity improvement(OR=21.317,95％CI 11.756～38.653,P＜0.001)were the influencing factors for patients who did not undergo vitrectomy.Conclusion Previously not receiving retinal photocoagulation treatment,combined with other serious systemic diseases,and preoperative visual acuity improvement are the influencing factors for patients not undergoing vitrectomy.Early knowl-edge popularization should be strengthened,targeted communication with patients should be carried out,and patients'confidence in surgery should be established.
