Application of anterior segment optical coherence tomography in descemet membrane detachment after cataract surgery
Objective To observe the location and extent of descemet membrane detachment(DMD)after phacoemulsification by anterior segment optical coherence tomography(AS-OCT),and to quantitatively evaluate its severity,so as to guide clinical treatment.Methods The clinical data of 39 eyes of patients diagnosed with DMD after 1 d of phacoemulsification and intraocular lens implantation from February 2021 to May 2023 were retrospectively analyzed.The corneal edema area was observed by slit lamp microscope and DMD grading was performed;the length of detachment,the height of detachment,the increase of corneal thickness in detachment zone and the increase ratio of corneal thickness in detachment zone among different degrees of DMD were measured by AS-OCT,and the correlation between the above quantitative indicators was analyzed.Results In this study,12 eyes were limited small detachment,accounting for 30.769％;10 eyes were mild detachment,accounting for 25.641％;9 eyes were moderate detachment,accounting for 23.077％;8 eyes were severe detachment,accounting for 20.513％;there was no complete detachment in this group.There were statistically significant differences in the length of detachment,the height of detachment,the increase of corneal thickness in the detachment zone,and the increase ratio of corneal thickness in the detachment zone among different degrees of DMD(P＜0.01).Pearson correlation analysis results showed that there were significant correlations between the length of detachment,the height of detachment,the increase of corneal thickness in the detachment zone and the increase ratio of corneal thickness in the detachment zone in DMD patients(P＜0.01).Conclusion AS-OCT can quantitatively evaluate the severity of DMD after cataract surgery,which is helpful to guide its clinical diagnosis and treatment.
