RESUMO
AIM: To observe the clinical effect of foldable capsular vitreous body(FCVB)implantation on ocular trauma and silicone oil-dependent eyes.METHODS: A prospective case study was performed on 17 cases(17 eyes)with ocular trauma and silicone oil-dependent in the First Hospital of Changsha from October 2017 to April 2022. All patients underwent FCVB or silicone oil removal combined with FCVB implantation. The follow-up time was 6mo, and the visual acuity, intraocular pressure, ocular axes, normal external appearances and FVCB were observed at 1wk and 6mo after operation.RESULTS: Only 6 cases had visual acuity before operation, and there were no statistical differences in the visual acuity before and at 1wk and 6mo after operation(P>0.05). The intraocular pressure was low before operation, but it was elevated at 1wk and 6mo after operation. The axial length was unchanged at 1wk and 6mo after operation, and the appearance and structure of eyeball were well maintained, and FCVB was stable with no atrophy during the follow-up period.CONCLUSIONS: FCVB implantation can preserve the appearance of eyeball, and avoid atrophy of eyeball and repeated operation, which has favorable clinical application value in the treatment of ocular trauma and silicone oil-dependent eyes.
RESUMO
@#AIM: To investigate the clinical efficacy and safety of the foldable capsular vitreous body(FCVB)implantation in the treatment of severe ocular trauma and also explore the effect of ciliary body function on the FCVB implantation. <p>METHODS: This study retrospectively analyzed 10 cases(10 eyes)with severe ocular trauma which had accepted FCVB implantation performed in Affiliated Xiaolan People's Hospital, Southern Medical University from January 2018 to July 2020. Ciliary body function was judged by score which was made by preoperative examination results. The case which scored 5 or less was studied as ciliary failure: 8 eyes scored more than 5, 2 eyes scored 5 or less. Followed up for 1-31mo, the postoperative best corrected visual acuity(BCVA)and intraocular pressure, anterior chamber, retinal reattachment, FCVB condition and adverse reactions were observed. <p>RESULTS: The operations of 9 eyes with aphakia eyes were successful. Iridodialysis occurred during the operation of 1 eye with lens. Retinal reattachment was found in all 10 eyes, and the position of FCVB in all patients was proper. There was no severe adverse reactions. Comparing the preoperative and postoperative BCVA and intraocular pressure, the difference was not statistically significant(<i>P</i>>0.05). In the group(8 eyes)that ciliary body function scored more than 5, 2 eyes had a supplementary operation individually, 1 eye underwent 2 supplementary operations. In the group(2 eyes)which scored 5 or less, supplementary operations were performed 5 times in 1 eye, only 1 time in the other one case. <p>CONCLUSION: Implantation of FCVB is a safe option to treat severe ocular trauma. But the postoperative visual acuity cannot be improved. The ciliary body function associates with persistent intraocular hypotension and shallow anterior chamber after FCVB implantation.

@#AIM: To explore the efficacy and safety of foldable capsular vitreous body(FCVB)in the treatment of severe ocular trauma and silicone oil dependent eyes.<p>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.<p>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.<p>CONCLUSION:FCVB could effectively and safely prevent eyeball atrophy in the treatment of severe eye trauma and silicone oil dependent eyes.

RESUMO
@#AIM: To discuss the surgical method of foldable capsular vitreous body(FCVB)implantation and evaluate its therapeutic effect.<p>METHODS: We retrospectively analysis of 73 cases with severe ocular rupture injury after FCVB implanted and silicone oil dependence after vitrectomy in our Hospital from April 2018 to March 2020. The visual acuity, corneal, anterior chamber depth, intraocular pressure, retina, FCVB status, their satisfaction with appearance is observed after treated from 1-20mo.<p>RESULTS: All the 73 patients in this group were successfully operated. The amount of silicone oil injected into the FCVB during the operation was 2.4-4.2mL, with an average of 3.5±0.36mL. There were 22 eyes with light perception, 46 eyes with manual perception and 5 cases with immediate index; 19 eyes during postoperative follow-up. Corneal clarity or basic clarity was observed in 19 eyes, corneal local opacity in 31 eyes, and corneal grayish white opacity in 23 eyes. There were 32 eyes with normal anterior chamber, 23 eyes with shallow anterior chamber, and 18 eyes with completely disappeared anterior chamber. The intraocular pressure(IOP)could not be tested in 22 eyes due to cornea, 17 eyes with IOP less than 8mmHg, and 34 eyes with IOP between 8 and 21mmHg. Slit-lamp microscope examination showed no obvious deviation of the position of FCVB. The postoperative appearances were satisfactory and basically satisfactory in 52 eyes(71%). No balloon rejection, sympathetic ophthalmitis or other obvious surgical complications were observed in all cases.<p>CONCLUSION: For the patients with severe eyeball rupture and silicone-oil-dependent eyes, the FCVB implantation can prevent from eyeball extraction. The operation is safe and effective, and the eyeball shape and intraocular pressure can be well maintained.
