AIM: To evaluate the effects of foldable capsular vitreous body(FCVB)implantation on the treatment of severe ocular trauma and late silicone oil-dependent eyes due to severe ocular trauma and recurrent retinal detachment.

METHODS: We retrospectively reviewed the four patients(four eyes)with FCVB implantation at our hospital since November 2017. Out of these 4 patients, 2 were males and 2 were females, with an average age of 31.5 years and an average intraocular pressure(IOP)of 5.6mmHg pre-operatively. Among those 4 eyes, 3 eyes underwent silicone oil tamponade due to severe ocular trauma and the other one was recurrent retinal detachment in silicone oil-filled eye. Standard pars plana vitrectomy(PPV)was performed, and the FCVB was triple folded and implanted in the vitreous cavity of four eyes. The retinal was assessed, as well as visual acuity, IOP, FCVB condition before and after treatment, and applied therapy.

RESULTS: All of those 4 eyes underwent successfully implantation of FCVB, which remained its proper position. During 1-3mo follow-up, the mean visual acuity was no different compared with pre-operative values. However, the average IOP was 10mmHg postoperatively. In addition, no retinal detachment was found using B-scan ultrasound after FCVB implantation. Moreover, FCVB-supported fundus was stable and no complication was found.

CONCLUSION: FCVB implantation is a safe and effective method for the treatment of severe ocular trauma and late silicone oil- dependent eyes. It can maintain the morphology as well as IOP of those eyes.
