Outcome Measures
Primary Outcomes (1)
Complete retinal reattach rate at the three years after implantation of the silicone-filled FCVB
FCVBs filled with balanced salt solution (BSS) were removed from all 11 cases, however, the risk of retinal redetachment and blindness rises after earlier FCVB removal. Approved by the Sun Yat-sen University Medical Ethics Committee, the removal of the FCVB will be decided by doctors depending on the conditions of eye. The eyes implanted with the silicone oil-filled FCVB are still under observation.
three years after implantation of the FCVB
Secondary Outcomes (1)
visual acuity, intraocular pressure, axial length, ocular inflammatory response, the number of corneal endothelial, anterior chamber angle and ciliary body change, morphological changes of the ocular and FCVB.
Before surgery, 3days,1 week, 2 weeks, 4 weeks, 8 weeks, 3 months, 6 months, 9 months, 1 year, 1.5 years, 2 years, 2.5 years and 3 years after surgery, and 3 months after the removal of the FCVB
