Study On The Correlation Between SFCT Value And Anatomical Closure Of Idiopathic Macular Hole

Purpose:Using optical coherence tomography to enhance deep imaging,collect relevant data,and use statistical methods to analyze,evaluate the postoperative hiatus closure,compare and analyze multiple related factors,in order to find a better objective index for evaluating prognosis.Methods:Retrospective clinical research.Sixty-six eyes of 63 cases of IMH patients diagnosed by optical coherence tomography with enhanced deep imaging from September 2018 to September 2020 in the Ophthalmology Department of the Second Affiliated Hospital of Nanchang University.All patients underwent phacoemulsification and intraocular lens implantation,pars plana vitrectomy(PPV),internal limiting membrane(ILM)peeling and silicone oil filling.Use Optical coherence tomography(OCT)images to measure preoperative parameters and observe whether the macular hole is closed after surgery.Results:Follow-up was 3 to 6 months.After the operation,56 eyes of group A were closed and 10 eyes of group B were not closed.The hole closure rate was 84.8%.There was a statistically significant difference in SFCT values of patients in group A and group B(195.77±55.53 um vs 139.35±26.05,t=5.088,p=0.000).SFCT was significant correlation with macular hole closure after IMH operation(OR=0.34,P=0.013),but not with symptom duration and minimum diameter.Conclusions:1.Postoperative closure of idiopathic macular hole is related to the minimum diameter of the macular hole and the duration of symptoms.SFCT value is an independent factor influencing the closure of the hole after IMH.Compared with factors such as the minimum diameter of the macular hole and the duration of symptoms,the SFCT value may be more predictive of the closure of the hole after IMH.2.IMH patients whose symptoms last less than 6 months or the minimum diameter of the hole is less than 400 um may have a higher closure rate after surgery.
