Clinical Study On The Application Of Foldable Capsular Vitreous Body In Severe Ocular Trauma And Silicone Oil Dependent Eyes

Objective:To explore the efficacy and safety of foldable capsular vitreous body(FCVB)in the treatment of severe ocular trauma and silicone oil-dependent eyes.Method:A retrospective study.20 patients with who were underwent FCVB implantation due to severe ocular trauma and silicone oil reliance conducted in our hospital from May 2018 to May 2020 were select as observation group,10 previous severe eye trauma patients without FCVB implantation as control group.To record the vision acuity(VA),intraocular pressure(IOP),exophthalmos,eye axis length,retinal reattachment,and complications of preoperative and postoperative in observation group and control group.A 1-year follow-up was carried out to compare the changes in the observation indicators of each group to evaluate the effectiveness and safety of the FCVB.Results:The average postoperative visual acuity score of the balloon group was higher than the preoperative visual acuity score,and the difference was not statistically significant;the average eyeball protrusion was(11.00?2.99)mm,which was not significantly different from the preoperative average eyeball protrusion(t=-0.632,p=0.535),the difference is not statistically significant;the average axial length is(23.16?0.83)mm,which is not much different from the average preoperative axial length(t=-1.807,p=0.087),The difference was not statistically significant.The final intraocular pressure score after operation was higher than that before operation(z=-2.296,p=0.022),and the difference was statistically significant;the average preoperative eyeball protrusion in the control group was(12.70?0.94)mm,eyes The average axial length was(23.79?0.55)mm,which was significantly greater than the average preoperative eyeball protrusion in the balloon group(t=-4.033,p<0.001)and the average preoperative axial length(t=-3.958,p<0.001),And the difference is statistically significant.However,the mean value of eyeball protrusion in the control group at the last follow-up after operation was(8.60?1.57)mm,and the average axial length was(20.64?0.97)mm,which was less than the average value of preoperative eyeball protrusion(t=10..077,p<0.001)And the mean value of the preoperative axial length(t=9.320,p<0.001)and the difference was statistically significant,and it was also smaller than the mean value of the balloon group’s last follow-up eyeball protrusion(t=2.364,p=0.025)and the last follow-up The average axial length(t=7.386,p<0.001),the difference was also statistically significant.In the balloon group,the retina was well attached,and there were no serious adverse events such as silicone oil emulsification,secondary glaucoma,and endophthalmitis.Conclusion:FCVB could effectively and safely prevent eyeball atrophy in the treatment of severe eye trauma and silicone oil-dependent eyes.
