METHODS:A retrospective study. Totally 20 patients who were underwent FCVB implantation due to severe ocular trauma and silicone oil reliance conducted in our hospital from May 2018 to October 2019 were select as observation group, 10 previous severe eye trauma patients without FCVB implantation as control group. The visual acuity(VA), intraocular pressure(IOP), exophthalmos, eye axis length, retinal reattachment, and complications of preoperative and postoperative in observation group and control group were recorded. A 1a follow-up was carried out to compare the changes in the observation indicators of each group so as to evaluate the effectiveness and safety of the FCVB.

RESULTS: Before and 1a after operation, there were no statistically significant differences in VA, eyeball protrusion, and axial length of the observation group, but IOP was significantly increased. The preoperative eyeball protrusion and axial length of the control group were larger than those of the observation group, but they were smaller than those of the observation group during the 1a follow-up. The eyeball protrusion and axial length of the control group were also significantly reduced 1a after the operation compared with the preoperative baseline. Retinas were well attached, silicone oil emulsification, secondary glaucoma, endophthalmitis and any other severe adverse event were not even occurred in the observation group.

CONCLUSION:FCVB could effectively and safely prevent eyeball atrophy in the treatment of severe eye trauma and silicone oil dependent eyes.
