Methods: this study is a retrospective case series report study. Patients with malignant glaucoma after glaucoma filtering surgery treated by Nd: YAG laser in our hospital were collected retrospectively. The intraocular pressure, anterior chamber depth and uncorrected visual acuity of the patients at different time points before and after operation were compared. To clarify the clinical application effect of Nd: YAG laser in the treatment of malignant glaucoma after Qingguang filtration. Through Spearman correlation analysis of preoperative clinical characteristics of patients with intraocular pressure and anterior chamber depth at 3 months after operation, the correlation between preoperative clinical characteristics of patients and treatment effect was clarified. Results: the study included 35 eyes with malignant glaucoma after glaucoma filtering surgery from January 2015 to July 2021. The results of comparison between preoperative IOP and postoperative IOP at different time points showed that the IOP of the patients at 1 day, 3 days, 1 month and 3 months after operation was lower than that before operation, and the difference was statistically significant (p<0.05). The results of the comparison between preoperative anterior chamber depth and postoperative anterior chamber depth at different time points showed that the anterior chamber depth of the patients increased significantly at 3 days, 1 month and 3 months after operation, and the difference was statistically significant (p<0.05). The comparison of the patients' visual acuity at 3 months after operation and preoperative visual acuity showed that the proportion of patients with visual acuity > 0.8 at 3 months after operation was significantly higher than that before operation, and the proportion of patients with visual acuity < 0.05 was significantly lower than that before operation, and the difference was statistically significant (p<0.05). The results of correlation analysis showed that the age, gender, onset time, preoperative intraocular pressure and axial length of the patients had certain correlation with the intraocular pressure and anterior chamber depth at 3 months after operation (P<0.05). Conclusion: Nd: YAG laser technology has good clinical therapeutic effect on malignant glaucoma patients after glaucoma filtering surgery. The therapeutic effect of Nd: YAG laser technology has certain correlation with patients' age, gender, onset time, preoperative intraocular pressure and axial length.展开更多
